Which will provide better flex. IRO 3-link vs Treks Y-link?

Like the title states, I was very interested in buying an IRO 6.5" LA 3-link but I'm looking for quality in the long run. Would I be better off buying the Y-link through treks or would the 3-link IRO hold its weight?

I've read a good amount so far but seeking more opinions on this exact question.


Edit: My largest concern would be the fact IRO is considering going to only adjustable LAs, though they haven't yet. Where as Treks Y-link is adjustable.

flex depends on a lot more than what LA's to pick

Assuming you were to use the same components with both of the LAs...I understand its not all on the arms.

Have you looked at the RK X-factor three link? I had this set up on my TJ. Was AWESOME. Out flexed the radius set ups others in my group had. Is super beefy to. Just throwing that option at ya.

Yes though its quite expensive considering if you are buying the Treks setup you also get good armor from their belly pan.

Depends on what kind of money you want to spend. I've heard nothing but good things about both. I'd go with the treks, the selling point is the belly pan. Oh and the iro is not a 3 link, its a radius arm just like the treks. And non-adjustble arms a good if you are 100% you'll never have to move anything a 1/4 inch..ever!

This is my dilemma. I have heard nothing but good things from both as well. Though for the money i'll be spending and plan on this being one of the final bolt ons for my suspension i'll be doing, I would like to not go the wrong route in the long run.

For a bolt on front suspension of a Cherokee, both will flex the same.

Most long arms, regardless of 3, 4 or radius arms will flex the same. Other factors such as shocks, brake lines and trackbar become the limiting factor.

IRO's will flex better. The 3-link setup doesn't have the binding that radius setups have.


By the way, if you call IRO, you can get the option for adjustable arms instead of fixed.

IRON ROCK OFF ROAD: XJ Critical Path Long Arm Upgrade

They have the option for the upgrade kit but I don't see it listed for the long arm complete kit but I'm sure you can get em to send you adjustables if you want em.

The IRO kit is not a 3 link. The IRO Y Link Radius arms scare the poop out of me. The caster adjuster bracket that scares the hell out of me.

IRO is big in the WJ world and I run their track bar on my XJ but you couldnt pay me to run those links.

Run the TNT and when you get to buggy status build a 3 link.

It's not?

Quote:
NOW HIGHER CLEARANCE AND BETTER TIRE CLEARANCE! We use an exclusive, non-binding, 3 link setup that has a pair of front long arms that will flex more than you thought possible. You WILL NOT bend these long arms as they are made from 5/16" wall DOM tubing. The bushings at the unibody are greasable super-flex joints that pivot to give as much suspension travel as your shocks will allow. We combine that with factory style rubber bushings at the axle for superior road noise and vibration dampening. As always, this kit is 100% bolt on! NO WELDING and only minor drilling is required for installation. No adjustment is necessary in any part except for our unique caster adjustment bracket that allows 7.5į of adjustability; plenty for any lift height from 4.5-8"!!
It attaches to 3 spots on the axle, making it a 3-link but you can call it a radius setup if you wish cuz it's somewhat similar.

I've heard nothing but good feedback from xj owners running this kit. There doesn't seem to be any issue with the caster brackets and if you are iffy about em then you can just ask em to give you adjustable arms instead.

A 3 link would have 3 separate links.

It is Y link radius arm setup with an upper y link removed.


Its identical to the TNT setup minus the upper on one side.


IRO

The caster adjust bracket scares many including myself, though with a thread over on NAXJA for IRO customers so far, with over 125 replies not a single person has complained or had an issue with it yet.

It is a radius arm. By your logic, the Treks radius arm is a 4 link, you think that looks anything like the stock style suspension?

Then someone outta tell Iron Rock Off road to stop calling their kit a 3-link. Until that happens, I'll continue calling it a 3-link.
