coil questions..


Active Member
It wasn't the smartest thing Ive ever done but I put a Fabtech long travel kit on my s10 and even with almost a massive 9" of travel, needless to say it needs alot of help. The truck is ex-cab and has a V6 but I went with the 4cyl coils for a better ride. It rides way to soft and rides on the bumpstops way too much. Fabtech offers 6cyl coils but it reverses the problem(no down travel). I need something with the same spring rate as the 4cyl coil but about 1" longer. I figure that would work with some 3/4 ton suburban bilsteins in the front for romping purposes. I know CST makes 4 different coils for their kit but nobody seems to know which one is best for my setup or if they will work on a Fabtech kit. I would have some custom coils built but they are expensive and I am already spending all my money replacing balljoints-haha. Thanks for any help-its greatly appreciated.

Does brand R make lift springs ? If they do, get a set from 4wpw and try them. If they don't work, take em back. At least then you'll have a spring rate to start from as brand R publishes that info in their catalog.

The reason nobody can tell you what CST spring will work is because everybody is looking for something different out of their springs. You want a taller spring with the same rate as you have now? Toss a spring spacer in there. But like you said, a taller spring limits the amount of rebound travel as the arms will sit closer to the stops. There is no reason a CST spring should not work on your Fabtech kit.

The CSC-C2-3 is for the extra cab 4-cylinder trucks... and the CSC-C1-3 is for the standard cabs. If you are running a Fabtech spring now why don't you call Fabtech and find out what the spring specs are - if you do that I can tell you what the CST spring specs are and you can go from there.
