    I am putting 4 inch blocks in the rear of my truck. I know it isnt the best thing in the world. Which order should I put the rear back together. Springs, shims, block? Or springs, block, shims? Thanks guys.

    Why are you putting shims on your truck anyway? You shouldn't need them for a 4" lift. Now, if you were running a 9" suspension like me, I could see why. To answer your question, they go between the spings and blocks. What size tires are you running?

    I am putting an 8 inch lift on the K5. Drew dropped my case and now he is workn on the front springs. I cant find the manual for the lift so I am kinda stretching for help. And hes never put blocks on a lift bigger than 6".

    The super lift kit came with 8" front springs with a shim already attached. Its got 4" rear springs and four inch blocks. The shims that came with it arent attched but look like 6 degree shims. So yes, I am running 4" springs and 4" inch blocks.

    I'm running a 6 degree shim on my rear. I have a 2.5 on the front too. Does Superlift not make 8" rear springs? I have Skyjacker 8" rear springs and thought that Superlift made them in 8" as well. Hmmm guess I learn something new every day.

    Yeah, Superlift does make 8" rear springs, but they are the 'firm ride' springs. There is no bottom overload leaf on these springs. They are just heavy duty, square cut on the ends of each leaf.

    My guess, deothrwhmt is using the 4" Super Ride springs, which are a soft riding set up.

  9. The Shim needs to be between the axles perch plate and the block and then the spring needs to go ontop of the blocks.


    So Shim, block, spring

    Jackpot Wes!?!?! He has got the superride setup. I spent 7.5 hrs installing his lift yesterday. We put the shim between the block and spring. Thank you all for your inputs. We are going to swap out the blocks as soon as he has enough dough to get the ORD flip. That way I can install it when I am doing mine.

    Misc. parts needed for this was a bunch 'o' grade 8 bolts. Moly-Graph grease and brake fluid all from Pep Girls. This may vary for someone elses application. Now all we have to wait for is extended shafts from Tom Woods.
