            PRODUCT FITS 2004-2006 LONG WHEEL BASE UNLIMITED TJ - PROVIDES 10" REAR STRETCH ON STANDARD TJ

            Engineered from the ground up to go Beyond Boundries..

            We incorporated some twisted IRO ideas with some conventional suspension design logic and came up with the TJ Premium Long Arm Kit. Where others are lacking, IRO has stepped up and delivered a feature packed, precise performing system.

            TAKE A LOOK AT THE KEY FEATURES:
            • Fully Adjustable 3 Link Front - The only limit to your non-binding suspension setup will be the length of your shocks. All 3 links are independently adjustable allowing an infinite range of axle positions.
            • Adjustable Double Shear Front Track Bar - This unique and carefully designed feature works with your 3 link front to center your axle. Jam nut free design will never clunk.
            • LCG Compatible - The front suspension and track bar require no lift and no bump stop extensions to work! The rear requires only 3" bump stop extensions.
            • Fully Adjustable Triangulated 4 Link Rear - Doing away with the rear track bar, this system really flexes. An over axle truss is required and it is included for your choice of rear axle.
            • Extremely High Clearance Belly Skid - Go from approximately stock location all the way up to completely flat with the frame.
            • Modular Mounting System - Independent transmission mounting crossmember allows the belly skid to be easily removed while leaving the transmission/transfer case securely bolted in place. Additionally, you can remove the transmission crossmember and leave the suspension completely installed and untouched.
            • Innovative Transfer Case Linkage Bracket - The first and only system that mounts entirely to the transmission (no more body side mount to cause issues or come apart under flex).

            Expect the best when you install this system with quality, performance AND value like no other. Also included with the TJ Premium Long Arm Kit:
            • Front and Rear Coil Springs
            • 2" x 5/16" wall D.O.M. Lower Control Arms. Pure beef you expect from IRO.
            • NO JAM NUTS - All adjustable links utilize IRO's exclusive threaded clamping terminals.
            • IRO Hydro Shocks Valved Perfectly for the TJ
            • Front and Rear Stainless Steel Braided Brake Hoses
            • IRO Sway Bar Disconnects


            PRODUCT NOTES:
            1. It is highly recommended to use a slip yoke eliminator with this system. IRO recommends the Mega Short.
            2. 1" motor mount lift is highly recommended.
            3. Installation requires cutting grinding and welding.
            4. Requires custom exhaust. (IRO exhaust coming soon)
            5. Requires removal of rear sway bar.
            6. Ships powder coated black. Pink was for display purpose only.

            My 23 year old son and I put this lift on with the help of my buddy and his hydraulic car lift. It was a lot of work and a bit of figuring out, but it is very quality pieces. I also went with the slip yoke eliminator IRO offers and I couldn't be happier. I've had my jeep all twisted on the trail and it goes right back to shape when I get level again. This kit can compete with any of the high end stuff, especially if you put on King or Fox shocks. The brake lines they send are ridiculously long! I laughed when I first saw them. But when I got on the trail, I saw why they are so long,,,cause the kit really articulates, and I mean massive, No joke kinda kit. And the customer service is outstanding with these guys, They won't leave you hanging.

            Really impressed with this lift. The day after this lift was put on, i took it off road to Uhwharrie and did every trail there with ease. Now the only limit to my flex are my fenders. It rides amazingly well on and off road. Every component is beefy that looks like it will last years of use.

            Thoroughly impressed with this long arm kit. Very inclusive and fairly easy to follow instructions. Figuring out how the long arm mounts installed on the Jeep was the only real challenge. Kit performs great and has a really nice ride and feel to it. Super beefy and well designed. Can't wait for years of enjoyment. Thanks for putting together an awesome lift and having awesome customer service.
