i am just wondering what spring rate and weight u guys are running in your silverados that are running 4 links or ladder bars?

 

you need to figure out the weight of the rear axle alone and the weight of the entire truck on the rear axle . 10 bolts weigh around 350 with everything.

on my truck i am going to use a 250-275 lb spring. mine weighs 5500 lb race weight 2200 on the rear

 

good advice chase... have u done ur 4link yet? if so u got pics u can pm me im browsing ideas..

 

negative i have all the shocks in place but the link is not even close , i have all the brackets from laser cutting but i need to get the pig running and that is first . rebuilding to a 436 to be even stronger this go to eventually change the turbos . i am making some jigs off the manifolds to make them with other options , t4 flanges and better location of wg merge from the collectors. this way i can keep the down pipes and charge pipes yet upgrade to gt37/40's eventually but for now im going to do minor mods to the mani's keep the 35's with billet wheels and aim for 9's

 

I'm using a 12" 200lb spring on mine. No track time yet so we'll see....

 

ok thanks guys mine is not close enough to weigh it but has a 15 gal alum tank and moser m9 thats narrowed 7 inches and ladder bars just need to finish the coil overs
