These are fantastic to drive compared to a traditional LSD, and in the snow they are a revelation. I disagree with the "no wearing parts" bit tho, I have had to replace 2 sun gears and side covers so far, they keep on galling. Quaife is happy to sell me the parts, but no offers on "lifetime guarantee". Yet. Still the best built ATB style diff on the market tho, just tear a competitors unit down next to a Qauife, and its immediately apparent.
Is the engagement of the planetary gears instant? On say a drag strip - when applying abrupt power - is there a period where spin needs to take place on one wheel in order to shift energy to the quaife planetary gears? Or is that time so small (less than a 10th of a second for example) that it can rightfully be labeled as "instant"? I've been meaning to buy one, and am thinking this is the week i will do it - but after being at the drag strip last night and really learning my problems, this is an answer i need. Thank you
I wonder what would happen if you guys made a competitor to the Tremec T56…🤔
It is something potentially on our development list, please keep an eye on our socials for any updates!
@@RTQuaifeEngineering, I know, it’s a HUGE ask, but the market demands it.💯 Right now, a Tremec Magnum T56 is the only aftermarket transmission with the clout to be trusted with 600+bhp/700+ft.lbs projects. Especially from classic car guys, like me.😁 I’m going sequential shifter to spare my engine a missed shift. The T56 will set me back 3.5-4K$(USD). The right aftermarket sequential shifter will rake me for ANOTHER 3k. If you guys could get around/under those sums, with comparable strength/reliability, you could blow the restomod game wide open.😶 Quaife is becoming one of those “trusted names” blue-collar car guys like me have come to respect. Especially in The States.💯 Even people who have regular T56s will likely upgrade. All-and-all, I’d pay around 8k$ for something like this.💯 However, if it were…say…A SEVEN SPEED…that really doesn’t exist ANYWHERE!😳 I’d consider up to 10k$(USD).🤷🏾♂️
Is this moneyshift safe maybe electronically controlled? One might accidentally flatshift down instead of up.
Hello, we do not provide anything that will stop the user from moneyshifting. However I can imagine a proper flatshift system with ECU could be programmed.

Greetings from Romania! Do you have diffs for the ARO 24x series off-roaders? Looking to buy rear and front diffs as they come with open from factory and only few have manual rear locker diffs, you cannot lock the front diff and it s a huge drawback.
Hello, please email our sales team on [email protected]!
Hi for Dacia Duster 2019 you have?Thanks!
Hello, yes. They are exclusively available from Mudster Romania, please see their website here: mudster.ro/en/
I knew someone who had a Norton 920cc commando engine with Quaife gear cogs, heat treated and cryogenically cooled to absolute zero -273 centigrade to cope with the high BHP the engine was producing, the gearbox was dissembled and all the bits sent off and then treated and returned in few weeks, not cheap but the thing never stripped a tooth or buckled a dog,
My I have an email address I want direct information about a product I am working on and need some parts
Hello, please email [email protected]
I know you made a batch of these for the 1st Gen Veloster, and I’m ordering one from KDM Tuners. Do you have a means of offering insight and advice for potential projects? A number or something to call? The G4FJ-T is a watered down G463-T, so I figure I may as well turn my Veloster into a bad Evo, and I’m interesting in using a Quaife solution for center and rear dif in a custom AWD set up! I am hoping to go for a fully mechanical set up because, well, that makes dealing with my own ECU easier, but also for longer term right to repair concerns. And I bet your team knows more about the available cases, housings, and what could be made to work together without a moment’s research than I could learn in a year of reading technical manuals.
I would recommend speaking to Momentum Motorsport as they are our EVO specialist (and all of our Evo products are exclusive to them). The best email would be [email protected]
@@RTQuaifeEngineering thanks!
Why would I choose this diff for the front diff in my 2008+ STI DCCD 6M vs the oem helical front diff it comes with?
Hello, our ATBs have more internal gears than a typical Torsen diff so will be more effective at biasing the torque meaning better grip.
@@RTQuaifeEngineering so you offer a front and rear diff or is this 1 diff interchangeable, front and rear, for my '08 WRX STI 6M driveline?
@@vannevels6758 Please could you kindly email [email protected] so we can send over the relevant documentation? Thank you!
Thanks + I would be interested if you performed an identical test in the wet.
in a VW T3 syncro would it make more sense in the front or in the back ?
You would notice the ATB more in the front due to the Haldex system prioritising the front wheels.
@@RTQuaifeEngineering the t3 is a rear we drive with a viscous coupling i can engage or disocnent.. I already have a diff lock in the back, was thinking to swap it to the font and put an ATB in the back - or - leave the difflock in the back and add the ATB to the front.. till nott sure
@@MsHappyeman Apologies, in the T3's case, as the drive is predominantly rear wheel drive, the ATB would be best suited for the rear.
Yeah, okay. I can move my diff locker to the front. Are you guys planning an ATB for the VW T3? Peloquin and GT make them. GT ones are very expensive (over 2000€) and Peloquin ones are nearly impossible to get. The market for VW T3 is really taking off and parts are needed. People who don't have the Syncro version also really like them in 2WDs to make them better all-round vehicles. Cheers from germany
@@MsHappyeman We are currently working with Charlie's Werkstatt GmbH in Germany for a batch of ATBs to suit the VW T3s! It would be worth speaking with them to get added to the list!
Why some satélite gears have two teeth joined?
Hello, I am not sure what you mean, hopefully this clip helps you: kzread.info/dash/bejne/h4WKmtaRlpmrm7g.htmlsi=nCIH0bTBUiSLVD5I&t=213
Hi, that screws what you tight on a moment in 1:07, on my differential loosen the screw and destroy the bearing... Now I have completly destroy transmission for that screw... You now how it is possible? I send my diff. back to quaife for complaint...
Hello, please could you email [email protected] so we can look into this for you? Thank you!
is it good as the WaveTrac or better? because i see similarities in the design!
The Quaife ATB was bought to market decades before the Wavetrac, we cannot comment on the which is better as we have no experience with Wavetrac. We have seen little evidence of the Wavetrac working effectively in these zero grip situations (plenty of videos on KZread). In our experience, you either need an ATB or a Plate Diff. Also, it is worth remembering that by adding friction (Wavetracs Carbon Plates), you are adding wear which cannot be avoided and they will need to be maintained more than the ATB.
All it would take for auto manufacturers to have limited slip differentials on all cars, is just a few gears... Instead, they add complex computers which try to do the same thing, but fail miserably. And also fail electrically some day.
Some people say its not recommended for daily use, if so , whats the reason why ?
Hello, they are designed as motorsport products so they can be used for track cars that travel to the circuit, however for use in a daily vehicle, we would not recommend.
I am planning to go 650-700 hp on my RS... could this gearbox cope with that amount of power? A while ago Mountune said that they have broken several transmisions on their 520 hp application, so i would say not at this point, but maybe you've made it stronger somehow... or not?!
Hello, all our customers are running 500+ with no issues. One customer is currently building their Focus RS to handle 700HP but the gearbox should be fine as it shares the same gear layout as our Honda K Series sequential where we have customers running 1500HP with no issues.
What engine tune you have on the RS? I can see that turbo needle going towords 2 bar, so not stock! What about top speed with 5 gears? I have a REVO stage 2 tune, 430 HP, 650 Nm
Hello, we have the Mountune M400 map on the car. With standard wheel size and 6000RPM and 3.938 final drive ratio, you would achieve 150MPH. With the 3.471 final drive ratio you would achieve 171MPH.
Hi. Does the Quiaffe only work when under load? Reason I’m asking is I have a 156 GTA that supposedly has one installed. I’ve jacked up one side and I can spin the wheel🤔.
Hello, the ATB is a torque multiplier so if one wheel has zero grip (for example, one wheel lifted) then that wheel will spin. For you to check if your car has an ATB, please carry out the following tests (both front wheels will need to be in the air): 1: Engine powered, driven through gears Wheels rotate in same direction 2. Not powered, gear selected, Rotate one wheel by hand other wheel should rotate in opposite direction
I want to add one to my Kia Forte GT but I haven’t heard of anyone who’s done it so I’m unsure if I should or not
Hello, what gearbox does your vehicle have? If it is the 7 Speed DCT gearbox then we manufactured a batch of differentials for Cherry Tuning, their website is: cherrytuning.com.au/
Hi, does it compatible with aftermarket clutch ? I had an Xtreme dual plate performance clutch in my car and willing to not replace it with the gearbox if it is possible.
Hello, yes we used an aftermarket clutch so you will have no issues with the Xtreme clutch.
I have 2 in 2 cars and never had a problem.
Put one of these on a 350z. Fantastic differential.
I have Quaife fitted to my car, how can i tell if the pre-loading was done correctly when it was installed? What would i notice if this wasn't done correctly? Also what does happen if one wheel has zero grip as people have mentioned above? Many thanks.
Hello, If the ATB is in a FWD application, then preload is typically only used for the diff bearings etc, if it isn't set up properly then you will experience increased diff bearing wear/potential noise. If the ATB is installed into a RWD unit, then you will have pinion bearing preload as well which again, if not setup correctly will have increased bearing wear and will sound horrible. If you are talking about backlash, then you will hear a constant whining noise if the backlash isn't setup up correctly. The ATB (and any Torsen type differential) are torque multipliers, so if there is a wheel with zero grip (i.e. in the air) then that wheel will just spin.
Does the Quaife not have an internal Wavetrac-type "load generator" in the event of wheel lifting or zero grip, rain, snow or ice to prevent it from behaving like an open differential?
Interested in hearing a reply to this.
No it doesn't, but the likelihood of the user ever experiencing zero grip is very slim. The ATB will work effectively in rain, snow and ice as long as the level of grip is the same on both wheels. We have seen little evidence of the Wavetrac working effectively in these zero grip situations (plenty of videos on KZread). In our experience, you either need an ATB or a Plate Diff. Also, it is worth remembering that by adding friction (Wavetracs Carbon Plates), you are adding wear which cannot be avoided and they will need to be maintained more than the ATB.
@@RTQuaifeEngineering Our experience is that the Wavetrac's will spin the inner wheel also, the situation just needs to be a bit more extreme (As in a bit more difference en tire resistance between left and right) Also wavetrac is quite a bit more expensive and it is a very specific setup that would justify that price difference.
Could you share a little more about the NVH levels of the helical gears? Do you have a video on a comparison of noise vs straight cut or helical?
I need quaife 69G 🤩
Power Rating?
We do not rate any of our replacement gearkits for power or torque, as they all retain the use of the standard sized gearbox cases and therefore shaft centre dimensions. Our gears will be stronger than the original parts, but this simply means that they can transmit more power through the original parts, which puts additional stresses and loads on the standard parts. For this reason we always state that our kits will only handle whatever the original gearbox was designed to safely handle.
@RTQuaifeEngineering I understand not sure if this is ok or not because my gear set has been updated although it's in the same stock trans case and stronger clutch to handle 450hp horsepower
Hi, I Have a Corolla AE86 RWD where to assemble the speed cabel conecter?
The gearboxes do not come with a speedo gear so you will need to convert it to a wheel speed sensor or another solution.
Is there a direct fit kit for AE86? Input shaft, bellhousing and shifter positioning?
Installed the QDF10L in my 2011 base touring 370Z and I love it! Pretty cool seeing how simple it looks for assembly. Maybe not simple, it's a mess of gears, but one can see the concept with assembly. The Zed should have come with this differential to begin with.
Glad to hear you are enjoying it!
I have a C63 AMG 507. 507 BHP. Would this set up be able to handle the torque of this car. I liked the video. I can see it being better than an LSD. But as i asked, could one be fitted in my high end car.
Yes this will not be an issue. Due to the design of the ATB it is incredibly strong. The crownwheel and pinion will fail way before the ATB differential.
Thank you.
Which is best for burnouts and doughnuts?
For a ford English axle on independence coilover.
A spool.
@@RTQuaifeEngineering Quaife ATB LSDs work for fun non serious drifting in snow and wet though, right? Or is a regular LSD better for that?
I was shocked to hear that they said people generally consider a helical diff to be worse than a plate diff on the track. I've always known it to be the opposite.. Helical is great for road courses.
Good Evening Gents! Great vid! Did I miss the recommended oil for servicing ? Please let me know! Thanks again!
Hello, we recommend GL5 75W90!
What about a mk3 ST? Does this kit compatible?
Yes for the Focus? If so this is QDF41Z
I went from an open differential 370Z to the Quaife QDF10L. What a difference! There's a spot where I have to pull across a busy highway to go up to the gate at my unit and with the open differential, I would typically spin and then the car would pull power (traction control). I saw my life pass before my eyes on a couple of occasions. WIth the Quaife, both wheels turn and while it can still spin when giving abrupt throttle input, it's much more controllable. I've had the diff on my Zed (as the UK calls it) for several years and I love it! The car should have come with this differential and I believe the new 2023 and up Zed has something similar to this type of differential.
very interesting, thank you very much
I wish these we 6 speed or more
I just want to know what is a quaife?
Thank you for the vid, awesome content. I have two more questions, if using electronicdownshift blip is it safe to also downshift without using the clutch and if temps exceed 105degree is there pre made ports for oil cooler or we have to make ones on the casing?
Hello, you can use the electronic downshift blip without clutch, however we would still advise using the clutch on downshifts. There are ports on both the 60G and 69G, the 69G has an internal oil pump. The 60G you will need to run an inline oil pump instead.
Great video guys, just got my 60g delivered yesterday! So in order to flatshift using a haltech 1500 ecu do I need anything extra? I’ve got the pot
You will need a loadcell gear knob as this will send a signal to the ECU to initiate the cut. However would be best speaking to Haltech to see what loadcell they recommend and if anything else is required for their ECU.
Fit an 850R?
No, this one is to suit the MMT6 gearbox. I believe you have the M56 gearbox, however we only offer a sequential for the M66 gearbox, please see here: shop.quaife.co.uk/shop/gear-kits/sequential-gear-kits/ford-focus-st-rs-mk2-volvo-m66-5-speed-sequential-gearkit/
just got my mr2's new e153 going with the ATB unit in it, ~250 miles on it and I'm beyond satisfied. just as good cornering as the KAAZ LSD my old one had... BUT i can turn without my car sounding like its falling apart.. the quaife just works. and no friction modifier... after experiencing clutched LSD's in a trans axle... never again. quaife's the game plan for my other mr2s from here on out
Love to hear the positive feedback and glad you are enjoying it!
1. What about the metal shavings that form when the worm pairs operate? 2. The axle shaft is connected to the satellite The satellite is connected to the worm The worms are connected to each other, but are not connected to the differential housing. They are simply in their seats. What causes blocking anyway?
Great vid, thanks. Recently picked up a 69G and very interested in seeing a teardown. Can't seem to find much info or manuals online, would like to maintain and service it myself. One question I had is you recommend to clutch in on down shifts, would there be any benefit to using the strain gauge to activate throttle blip on down shift or is it just all round better option to clutch in and keep it simple?
Hello, we have exploded drawings and a basic servicing guide that we can send over to you. Please email [email protected] so this can be forwarded over. It is on the list to create a basic servicing video for a more visual reference. We would recommend going with the simpler clutch in on downshifts.
Thank you, very informative👍
I have my order sheet in front of me and I’m just curious what gear set up is in the development car?
I used it on my Honda CR-X when I was younger. I chose Quaife (At the time, imports into Japan had only just begun.) because the clutch pack type makes a big fuss every time I have to do maintenance and I don't like the sound of the clutch pack working, and I couldn't go wrong with that choice. After all this time, I'd like to thank Quaife from the bottom of my heart.
Thank you for your feedback!
