x2 . I'm considering the IRO 5.5" LA ( http://www.ironrockoffroad.com/Merch..._Code=IR-Z5CPK ) or the RC 4" LA "extreme travel kit" ( http://www.roughcountry.com/jeep_zj_4xla.html ) Id rather fab some and save money but this is my first mod on the zj and I figure I might as well get a kit cause I don't weld...yet. Ive heard the 4" RC x-flex kit needs track bars, more CA's, brake lines and other junk so it seems worth it to get the full long arm kit. I'd end up spending about 400 bucks less after piecing the x-flex kit together. Does anybody have either the IRO 5.5" long arms or the RC Extreme Travel? I know there are plenty of discussions on this topic but none specific to either of these kits for the zj. Thanks for the input.
I just punished my IRO kit and it performed great on the rocks. I never needed to romp on the throttle ever getting around some boulder littered trails. I've also got a locked rear and 35" Goodyear MT/Rs so that helped a ton, but on short arms I would have probably broken something considering how difficult the trails were. The IRO LA kit has made me a real believer in long arms... there's just no comparison for off-road ability - no way, no how. Unfortunately, it's the only setup I've tried, and the design for the rear long arms could be better like Claytons but then you have to weld it in.
As for the RC extreme travel LA system, it has some design concerns IMO. Mostly, the front subframe is designed in a way that it's one piece. Servicing the transmission and transfer case will be a PITA without removing the front long arms and subframe. The rear doesn't seem to be as secure as IROs since it doesn't use a subframe, only has two LA mounts that bolt into the unibody. This one is argueable for strength though. Where the RC kit outshines IRO is it is much cheaper. IROs is proven though.
If I absolutely *HAD* to buy a kit, I'd get a rock krawler or TNT 3-link xj front and make it work, and then claytons rear.
That being said, I chose to build all of mine that way. If I had to pay for all the metal I wouldn't have saved much over buying the above. Just the joints alone (went with full rock krawler krawler joints) were $500+
Do any of you guys have any experience with the Full Traction long arm kit? http://full-traction.com/detail.php?...CTID=395&NOTES= I like the idea of full bolt on, but the way that rear axle piece bolts on seems kind of iffy. Then the price is more expensive than the Clayton kit.
go get one of those airmiles/rewards credit cards. then at least after you've spend a small fortune on jeep parts you can get the wifey a little something for free via gift cards to justify the spending ask me how I know..........
