Andrew ..... My opinion is you are doing the right thing. We race and pre-run in Baja Mexico and the trick is to have the springs just about holding the car up, so as soft a spring as you can get away with ........... Then make the shocks do all the work , in our case multiple shocks with Bypass technology ..... it takes testing and multiple tuning hours but it works. The soft spring and tuned shock let the wheel travel up and down over the terrain while the car stays level. Yes we are racing and going as fast over bumps as possible BUT in our pre-runners when we are driving the race course before the race we are heavy with camping equipment and going slower so we are trying to achieve the same as you are ..... I really think you will like your ride ....... The worst that can happen id you will occasionally hit the bump stops when fully loaded and going at speed ....... if that happens too much, a small adjustment to the shocks will sort that out ...... All the best from an Englishman in Baja CHEERS

As a former motorcycle road racer the process was to find the rebound/compression setting that was just enough to control the spring. Too much damping meant the wheels wouldn't follow the bumps and undulations and result in a harsh ride and reduced traction. The springs were chosen to allow the wheel to use the full suspension travel without bottoming out. We'd start with a very soft rebound setting and keep going up a couple of clicks at a time until the wallowing stopped. Compression wasn't as critical. I used the same process of trial and error to set the Koni Reds installed in my 4wd Nissan. I agree that once you've found a setting in the 4wd that's it ... it's not a race vehicle that needs constant adjustment and fiddling.

On setting suspension up is to determine we’re the shock sits in its travel range when loaded up. The perfect setup is a settled position at 1/2 to 2/3rds of its maximum extended travel range. If it sits under 1/2 then the springs are to soft

Mine is reasonalby heavily loaded most of the time (110L of water onboard, AluCab RTT, Internal drawer/shelving system). I've been really happy with the comfort of the 4 leaf parabolics on corrugations and sand tracks with 'wombat holes'.

They were pushing me for 600constant rear but I remember Andrew you talking prior about doing this. And think 450 was the rear you spoke about. I’ve not adjusted at all or added any weight so far. Front on speed humps is sometimes harsh. On the road all feels good. I’m pretty confident rear will work out. If front is a little over sprung I could loose up to 5mm on front and believe that will soften front right up. Then to fine tune the shocks..

Test the full articulation of your front suspension - not full droop of both wheels together - by jacking one side or drive up an incline on the side to make sure the front coils won't dislocate.

I see you have a scan gauge upfront....when are we seeing that install & what are you currently monitoring?

Did you do any measure if you gain any more suspension travel ?

Hi Andrew completely unrelated question. But how did you replace the pvs badge on the steering with a Toyota badge?

I think suspension should be the last thing to add or at least to setup. Until you know your final weight, I don’t see the point in doing even a test drive. Those parabolic springs caught my attention a while ago but I am too conservative to even consider them; at least for the type of travel I do. I do carry a lot of diesel, water, some heavy RTT and a few batteries. In 2022, I want to put my LC79 on a diet and/or at least move some weight forward.

Way to go re- parabolic springs, not sure how long the shocks will last. You do put a lot of weight on your rigs and I get your are trying to reduce it. Hope it works, there is a lot of money in that setup. I don’t have the luxury to swap and change so I find it difficult to relate to your rationale. Thanks for the insight though, your build is very interesting. You may need to upgrade to 4 leaf parabolic’s?

They said the 300kg 3 leaf were deemed not sufficent for the 78 series. So maybe they dont do them anymore?

Andrew, will be interested to see how you go. I’ve been running parabolics since 2010 on Landcruisers. My HDJ79 ‘bakkie’ 😄 has the same set up as you, BP51s & TT parabolics 300-500kg rated). I do however have airbags as I’m often changing loads or towing heavy trailers. I won’t be surprised if you end up with the heaviest TT springs in the end, once you do your fit out & load up with water. As for your comments about the 76, I have one as my overlander, the factory suspension was worst of the 6 cruisers I have owned, I did have parabolics on this also & it was awful. My fix was this was the full coil conversion which has fundamentally changed this vehicle in every positive respect. Coils unnecessary on the long wheel base 70s but the 76 it should be mandatory

@@GR8Tmate agree I have bp51s on my cruiser Ute and kings on my LC76 & the kings are worth the extra money. I certainly couldn’t go back to standard shocks after having remote res now

@@user-rv6zk1pp7r Yes, I’m building a new 78, I will be going Kings Remote Res, sure it’s slightly more expensive than the BO51’s but twice the shock. I find it odd that certain people will muck around with certain shock/spring systems when there’s obvious alternatives that are much better. They muck around with other combinations & end up spending a fortune chasing a better result which could of just been obtained by taking note of what’s superior. For me, I’m done mucking around with suspension, I’d rather play with other components that arnt such an issue when I get it wrong 😂

Soft sprung leaf vehicles tend to suffer from axle wrap. You may notice this when in 2WD

Hi. I have a severe height restriction with underground parking. Any suggestions to fix the ride without any lift?

970mm-925mm is 45mm. 😁. Other than that spot on (apologies could not resist)

Andrew, you have a problem - the centre hole on the TT pro bushes is 18mm and you've had it installed with the smaller (14mm) Toyota fixed pin. Thats why they slipped in so easy on installation. You will have 4mm of play. The Toyota fixed pin must be used with a Toyota sleeved bush which is what I used for the same TT parabolics in my Troopy. The shackle bushes should be OK because the factory shackle pins are 18mm. And incidentally the TT greasable shackles are 20mm longer if you find you want an extra 10mm lift.

And just to add my only problem with the 3-leaf parabolics is that they need a very strong shock to control the bounce you get with the dunes on the Canning. No inherent dampening. Normal shocks do not cut the mustard, and I was loaded to 3300kg so not over GVM.

I understand the need for shocks that will need to do more work, but I'll look into the pin issue. They should have used the TT supplied pins. Am thinking of swapping to the greaseable OME shackles. I do not want more lift. Good idea?

@@4xoverland ARB have put the original Toyota pins back in yours without realising the fixed pin is smaller. I looked at the parts on the ground and didn't see any TT pins. The TSK031 greasable shackle pins are a good idea because of the extra 20mm of length, and because they are greasable. The TT pro bushes actually are well sealed so the grease doesn't actually come out when you regrease them. TT told me there is no need to regrease them - just make sure they are well greased during installation. I had the TPK011 greasable fixed pin and found the centre hole in the probushes became elongated after the Canning in 2019. So I reinstalled the nice quality Toyota factory pin and sleeved rubber bush. I once had a greasable front pin break on the Gunbarrel about 10 years back so might have a bias against using a greasable fixed pin.

​@@4xoverland Have to see how your springs go when loaded. I expect you'll lose 20-30mm of height at the rear if loaded to 3300kg. Thats what mine does. I have the 20mm lift front springs (TTCS-1449) and it sits pretty much level at GVM.

I would have thought you couldn't over spring with parabolics as more of the spring is used as the weight comes on not all the time as with standard leaf springs.

Sorry, has this been painted/wrapped yet or still deciding?

Very interesting, are you guys allowed to put airbags in down there? If a shop was concerned with the idiot factor, they could just say, airbags for your loadout sir.
