Has anyone tryed the rear coil conversion by Rock Krawler offroad? If so any build pics?

x2, someone's gotta have some info or pics
they proclaim to have the perfect geometry on a system that provides the best highway ride quality....pricey, absolutely, (almost $3000) but the 6.5" triple threat long arm w/rear coil conversion sounds like its quite a beefy package that might be worth saving time, testing, & piecing together, no?

i'll give my input though. Its a good brand and have some high quality stuff. Looks meaty and strong. If you not into fabbing up your own rear end this would be a great way to go.

Since no one seems to know how to use google..I'll send ya my bill later..

c'mon man, dont ***.u.me, google's my bff....i've seen plenty of xj pics with coiled rears & found Co.'s that produce rear coil conversions, by searching google & CF, but i'd love to see these systems used, abused, & personal reviewsOriginally Posted by okcjeeper

yes Rock Krawlers' system is the beefiest (possibly most complete) kit offered with all the geometry, & trial & error factors removed, but has someone here purchased & have their input on it
i'd absolutely love fabbing my own system, but i dont kno how to weld (YET) & dont completely understand the geometry involved (YET)

I was looking at this kid when I had my Cherokee for a while. I chose against it because that $1600 for the kit doesn't include everything. You're going to be spending another $200-$500 for quality shocks and you still need to buy the coil springs. Missing key components like that made me look else where and eventually started designing my own.

You will need a lot of practice with welding in order to get good enough to make some good quality welds for coil conversion. There is a ton of stress going through these brackets that can easily sheer a bad weld. Also, be ready to start hitting your head against a wall, there is a lot of math involved in calculating the geometry of a coil sprung system. It is fun, though, once you start understanding it.Originally Posted by xj^REMY

yea, i realize this, & will not be trying this anytime soon.....i've got plenty of other projects/upgrades on the xj that need to be rectified before coils in the rear, not to mention, acquiring a welder (+ associated equipment), then practice, practice, practice....& because there isnt one specific way to accomplish a coil conversion, i am, for now, trying to atleast wrap my head around the geometry & what would the best set up for me & also get as much info from Co.'s that manufacture conversions, & weigh out the optionsOriginally Posted by Garvin

I'd say I agree with all of you..... I like building my own things, but don't think I know all of the geometry that goes into linked suspension setups. I was just curious if anyone had any experience with these kits? Installed one, heard of one, seen one on the trail? Its a lot of money to put into a mystery lift without feedback that isn't from the website of the company that builds the lift.

i know a couple guys that have the rock krawler rear conversion on their xj.
they like it and it is a well made kit.
but if and when i do it, i'll use staangs fab rear coil conversion.
it's built very well with good materials, but you do need to supply shocks and coils, but that is so you can match it up to your front height.
factory front cherokee coils in the rear will net you 6 inches with his kit.
last time i was talking to eric, i think his rear kit was about 1200 bux.

I believe he dropped that price, don't quote me on that though.Originally Posted by caged

But +1 on staangs, built like a god damn tank and its life time warranty.
