Need Help Picking YJ Lift

I'm going to be putting on a lift for my 89 YJ pretty soon, but I'm having trouble deciding which way to go. I want to run 35's on a 15x8 wheel. I like to ride the trails in Michingan's U.P. so I'll be driving it a long way just to get there so naturally I'd like to have a pretty decent on road ride. Here is what I've been considering:

5.5" Coil Conversion- who makes the best? besides the $3000 XCL. How is the ride with these?

Spring over- Does this give a pretty decent on road ride? I figure since I'd use the factory springs it couldn't be any worse right?

Shackle reversal kit w/ 4" springs and longer shackles in back- I've heard a shackle reversal is unsafe on road because the front end dives while breaking. Does anyone know about this?

Re: Need Help Picking YJ Lift

This has been discussed numerous times here, but I'll give you my 2 cents.
Coil conversion--Every coil conversion I've seen on YJ and CJ have a really bad squat problem on the steep stuff. Will take you mucho experimenting and time and money to dial in.
Spring over--Your best way to go, but has steering issues you will have to sort out re:bumpsteer. YJ springs have a tendency to sag real bad with SOA though.
Shackle reversal--IMO the most overrated mod in existence, and yes can cause strange behavior under heavy braking.
Bottom line--IMO your best bet is a quality spring under lift in the 4" size. Overall, your best bet is SOA, but a lot of work to put into stock YJ axles which are gonna break anyway. [img]images/graemlins/grin.gif[/img]

Re: Need Help Picking YJ Lift

I like my Rubicon express 4.5 extreme duty. if you flex, it wont fit 35s without a body lift or some new bump stops or body trim. also, I get some bump steer. it is not easy to drive, but it sure is fun. [img]images/graemlins/grin.gif[/img] the rear is a little stiff, but I don't have a hard top or a full size spare yet.

most kits come with bumps stops, the RE kit doesn't. But for 33 inch tires on the RE kit you really don't need them. I guess RE considers that extended bumps stops are for girly mans.

If you go SOA- use JCWhitney's rear CJ-7 leaves on all four corners. They flex well and hold up better than Wrangler leaves.
