Shocks: Stock Truck vs Pre-Runner

[BigDan3131]

What I would like to know is how much travel a stock trucks suspension travels compare to what would work on a pre-runner truck that will at most see little if any off road time for a while [cant break the truck until the other one is done].

It will have a 4" lift spindle and the springs are those from the GMC V6 trucks on the front and a three link with wishbone out back instead of leafs. Powered by a 514HP 6.0L LS backed by a 4L80E, tire size of either a 33" or 35" on 18's since I have them.

Since the truck has 8 lugs I can opt for the 1 ton rotors meant for dually trucks that space the front wheels out 8" further.

What would be a good choice for travel length up front and would 16" to 18" be enough in the rear?

Out of curiosity, have you lifted and lowered it on a set of jacks (no shock/spring) to see how far it wants to articulate unrestricted? Last one I recall working on (Ok, the only prerunner I've worked on) was an 88 Toyota, which ran around ~18" of travel and limit straps.

My lowered c10 has like 4" of travel up front and like 9" out back lol.

No drivetrain yet...sadly money had to go elsewhere. Those stock gmc v6 springs are meant to hold a 760 pound engine up and don't give at all. I will have a set of new fully adjustable upper arms that I can change both caster and camber on. Once I have it up and running then that's when all the changes will be made...too many ideas in my head!
