My rear leafs are lifted with a block and u bolts, what leaf springs can I go pull off at a jy that match up with a rc 4.5 lift?

 

S10 are pretty popular. Really any 2.5" leaf springs if you plan on using your main.

 

Just make sure that you account for the XJ having different lengths front and rear of the center pin; they are not symmetrical leafs.

By trial and error during building my pack, I found that "most" spring under vehicles have softer springs, while "most" spring overs are stiffer.

And watch that shackle angle when you're done!!

 

Good point. You can always redrill, but that kind of defeats the point of making it easy. and x2 on shackle angle, even with actual XJ designed packs that provide lift also leave you with a horrible shackle angle. Putting in shackle relocation brackets made more of an improvement in on road driving than the bilsteins. The added flex alone makes it worth the price though.

 

Well what kinda setup should I run? I mean if those are adjustable how do I know where to put the leaf at?
