Hi i'm currently doing a sas in my 94chev 2500 with a 6.5TD i'm looking for front leafs and possibly rears too if the price is right. i'm not sure what kind of leafs to run can anyone give me some info on what kind of springs to get. i'm going to run 37" tires so i want to get about 8-10" of lift in total. some pointers from people who have done this before would help too.

thanks

Chris

hey, if your asking on this site, your first change would be that you need to cut that lift down to about half of what your thinking. This is the wrong place for 10" lift...

I run a 37-13.5x20 on my suburban with an ORU hanger kit. my front springs are 4" tough countrys with a 1" zero rate. flex is good, ride is nice. I had 6" superlift softrides and wasnt bad, but the 4's ride better. if you are going to wheel it I would go with 6" springs and cutouts. mine only sees street duty and it still rubs now and then. also depends on the hangers you use. ORU's add 2.5" to spring lift, so I'm running about 7.5" of lift on mine.

for the rear I use stock springs with a shackle flip and lowered front mounts. you will probably have to get a lift spring due to the difference in factory mounts between burbs and trucks.

hope this helps, e-mail me if you want pics.

I would say to get some 52" long rear Chevy springs, and some 63" long rear Chevy springs for the rear. Maybe add a couple of leafs to get the right lbs/inch requirement for your truck. This should net 7" or so.

Try to stay around 8" lift.

What kind of wheelin' you lookin to do?

If you do alot of trails then I second the 52s. You can build your hangers to get the right amount of lift and even use a 1" zero rate or even cut a 5/8" overload leaf to fine tune.

well sounds like either a set of rear 52's or the 6" superlift springs will be my best bet. i still have a few questions

-what is a 1" zero rate and what does it do?
-how do i calculate the spring rate that i will need?
-what trucks have the 52" rears?

thanks

1" Zero rate spring is basically a 1" block that bolts to the spring pack.
The simple way to calculate spring rate is to add or subtract leafs until you get the ride/flex you want.
If your gonna be usin the truck on the street I would recommend using a sway bar and just get some quick disconnects for off roading.
And you’ll find 52" springs under the rear’s of Jimmy's, Blazer’s, and some 1/2 tone pickups.

so a zero rate is basically a 1" lift block?
Isn't there a way to caculate the spring rate that you would need by using the weight of the truck?

thanks
