Moderately old thread bump...

Are you running the stock drive shaft or did you change it out for a DC? You mention the DS in one of your posts, but no specifics.

Thanks.

Vehicle is riding great, using it everyday, awesome DD! :D Still running 300/400 so she's still a little lop sided lol... Just noticed I made a typo in OP #5, should be 300/400! :doh:

I was wondering. I just set mine up with 275/400 and think that 350/400 would be a bit high.

Regarding the lop-sidedness- why not just adjust the one side up? That's part of the beauty of Coilovers.
 
Maybe a happy medium with 325 over 400 or limiting the 300 travel bit more .. can you post pic how she ( your 80 ) sits in flat surface ..

Would be nice to see how much are the 300 compressed right now at ride height
 
Here are the pictures of my lean machine!

Can't you adjust the right driver coil to match? Nice work.

did you reuse some of the factory 80 series shock mounts .?

Didn't notice until now that are 15° inclined .. ?

No, cut the old ones off and had new ones fab'd up.

I can still adjust the right side more, just did today actually.

I think you either have a short coil or a much softer rate on the upper spring on the driver side. Look at how much more compressed your driver side spring is than the passenger's. 80's are really well balanced, so you shouldn't need a different rate one side to the other on the front. :cheers:
 
the 80 have diferent rates in the coils per side.. the driver side sit the driver and the gas tank
 
This is a custom Coil over setup. I doubt they purposely set different rates on the front as it could severely affect handling and cause issues like shown above.

Also, this is a LHD 80, so the driver and gas tank are on opposite sides.

I still think that he has different spring rates on each side which is not ideal considering how well balanced the front end of an 80 is. I have matching rates on both sides and mine sits level. It's obvious from the pictures that there is more space between the coil wraps on the passenger (right) side than the driver (left) side. This is indicative of a softer coil on the Driver (left) side which is also the side that is low.

Not true, it's a HDJ81 so it is RHD, being a diesel it has a turbo, intake, brakes, steering, battery, manifold/exhaust and myself all on the same side. Weight isn't even on the front of these and I have tried to compensate for weight difference already by adjusting coil overs but I will need a higher spring rate on drivers side to fully correct the issue.

Does it really add that much weight? Didn't think about everything they had to move for RHD. :doh: I was also getting myself confused by the right and left (totally backwards in my last post). Need to back to grade school I suppose...

Here you can see I was looking from the front:

Serious build - hats off! I am interested in the sliders - any room for customizing the kick outs? Guess I need to ask the builder.......:)
 
More mods to come in the very near future.
 
Nice 80, Just read your build. The 3 link setup really cleans up the front-end, and flexes so much. I really like it.
 
Some updates to the truck. For those who are interested in aftermarket rear axle upper links the one's utopoo was running essentially ripped apart over time and were constantly coming loose. Having bushings at both ends under high flex situations caused the links to constantly be turning. Other than that and some rework to the front set up the truck itself has held together quite nicely.

And now for the upgrades. The rear is going to be pushed back an inch to make room for 40's in the future. In the picture below you can see the new rear links, from LH to RH new lower, new upper, and a comparison to a stock upper I had kicking around. His rear factory lowers are bent from wheeling in the rocks so that problem should be cleared up with the heavier 0.250 inch wall tube. Rod ends are all Evolution medium ends with 3/4" hole, lowers are 1 1/4" shank and uppers are 1". Also using the Evolution weld on bushing with 3/4" hole. I will have fully assembled links once the rod end internals show up. For those of you wanting to use factory hardware with this set up give Evolution Machine a call they can make custom internals specifically for your application.



Next some 6 inch rear Slee heavy springs to replace the Slee 4 inch ones. I switched the right side for the left side due to the weight difference and the truck is currently sitting level. We will see how the springs settle in to determine if the front spring rate needs to be increased to eliminate his past lean issues.







New front rod ends from Evolution are also on the list as the old ones are pounded out and loose, not sure what the previous rod ends were. Used a Evolution large joint with 3/4" hole. These will be a huge improvement over the original ones used in the 3 link set up.





And finally in preparation for the larger tires a new custom front axle. We got an 80 series spec ruff stuff housing, and some Hellfire fabs knuckles.











More to come as the build progresses including some Evolution double ended ram assist steering.
