    The paramount suspension upgrade for your XJ is a long arm system. Iron Rock Off Road's ROCK-LINK 3 link long arm system offers unrivaled performance, giving your Jeep both the capability and ride quality improvements that you have been looking for. This ROCK-LINK long arm upgrade is built for strength, clearance, adjustability, flexibility, and ease of install.

    Minimum lift height required- 3"  

    • STRENGTH: Our subframe is constructed with 1/4" steel and our lower arms are even thicker at 2"x5/16" wall D.O.M. tubing.
    • CLEARANCE: We tuck our subframe up as tight as possible to gain you the critical extra clearance to keep your Jeep low and your belly high! The lower arm connections at the chassis are as high as possible with still being able to install a bolt through them. The control arms have an inboard bend to clear your tires, so you can steer lock to lock without rubbing on them
    • ADJUSTABILITY: All the arms have tons of adjustment built in for your stock situation to your stretched crawler.
    • FLEXIBILITY:Yes, of course we are talking about articulation, and the ROCK-LINK delivers plenty! But we are also talking about flexibility to install other axle combinations with ease. Use this kit with your stock Dana 30 for now, and then bolt in a Dana 44 or Dana 60 down the road!

    EASE OF INSTALL: No welding, no complicated setup or templates. All you need is a drill, a floor jack, some jack stands and some hand tools. This is a BOLT-IN kit, although if your preferred method of installation is welding, you can do that! (NOTE: most installers opt to cut off the factory lower control arm mounts on the chassis)


      KEY PRODUCT FEATURES:
    • 2", 5/16" thick wall D.O.M. lower control arm material
    • 1/4" thick, 3 piece, subframe assembly
    • Huge tire clearance with inboard control arm bends
    • Best ground clearance available with super high clearance long arm subframe mounts
    • Makes axle swaps much simpler!
    • Maintains caster through the suspension cycle
    • Easy to install without welding, only simple drilling is required!!! Seriously, you can install this in your driveway in a few hours! 

    IMPORTANT FITMENT NOTE: Front long arm system will not fit the 1999 XJ with the 4 cylinder engine and 5 speed transmission.  2000 and 2001 models with automatic transmissions will require old style transmission mount such as 2625

    IRO LIFT KIT BUYER'S GUIDE:

    Kit Types
    Short arm kits:
    What is a short arm kit? A short arm kit is a suspension system that typically utilizes the factory mounting points on the axles and the chassis for your control arms. These types of kits can use OEM control arms, heavy duty fixed length arms, heavy duty adjustable arms, OR any combination of these options. Short arm kits are the easiest system to install and upgrade, and are very versatile. These systems are best used in 0-4.5” lift range, depending on the vehicle. From daily driving to overlanding, to light rock crawling, these kits transform your Jeep into a swiss army knife. With a low purchase price, and fantastic performance gains over stock, these are a great bang for the buck!
      FOUNDATION SERIES
    • Most affordable option
    • Huge improvement over stock suspension
    • Clearance to fit bigger tires and drive over larger obstacles
    • Has all required parts with nothing you don’t need
    • Great “foundation” to build on!! Upgrade when it fits your build timeline/budget.
    • Kit utilizes short arms (not a long arm kit)
    • Simplest installation, using basic hand tools. Minor drilling may be required.
      BENCHMARK SERIES
    • Contains all “Foundation” kit features PLUS:
    • Includes most common and value packed upgrades over the Foundation Series to remain budget friendly.
    • Easy to upgrade without purchasing duplicate parts.
    • Kit utilizes short arms (not a long arm kit)
    • Still a simple install, basic hand tools required. Minor drilling may be required.
      PREMIUM SERIES
    • Contains all “Benchmark” kit features PLUS:
    • Includes premium level features such as adjustable control arms, adjustable track bars, stainless steel braided brake hoses where applicable.
    • Highest performing short arm system
    • Kit utilizes short arms (not a long arm kit)
    • The best for mild lift height builds for all around versatility, adjustability, and durability.
    • Basic hand tools for installation. These kits usually contain several components with adjustments so we view this as a medium difficulty installation. Some minor drilling may be required.
    Long arm kits:
    What is a long arm kit? Long arm suspension systems use a chassis mounting system that allows a much longer control arm set to be installed. Why? This allows for a flatter operating angle for and more straight up and down axle movement through the suspension cycle. The benefits include an improved ride comfort than otherwise equally equipped short arm suspension, significantly reduced binding allows more articulation keeping your tires on the ground longer, meaning more traction without the use of traction aides (like limited slip or lockers). Long arm systems often have easier provisions for swapping in different axles. The ROCK-LINK kits are Iron Rock’s answer for a premium long arm system. These systems are the best choice for modern installers since the benefits are “next level” when compared to any short arm systems. These systems are best used in 3-8+” lift range, depending on the vehicle. The installation can vary from simple to difficult depending on the system or vehicle application.
      ROCK-LINK
    • Contains long arms in the front and short arms in the rear. This combines the premium performance benefits of a long arm system and the great value of short arms or leaf springs ;-)
    • Stronger than stock
    • Great for both high ground clearance builds as well as low center of gravity builds
    • Typically does not require exhaust modification.
    • Best for lifts above 3.5”, from daily driver to aggressive off-road driving style, including rock crawling!
    • Easy to upgrade by adding rear long arms at a later time. This allows you to build up to the ROCK-LINK PRO in stages as your budget allows.
    • Installation is usually longer than short arm kits due to the quantity of parts replaced/upgraded. Difficulty level is medium. Basic hand tools required. May require minor drilling/cutting.
      ROCK-LINK PRO
    • Includes all ROCK-LINK features but upgrades from the short arms (or leaf springs) in the rear to a long travel, long arm system.
    • Great for any and ALL builds 3.5” and up. These kits EXCEL in ride comfort with also providing maximum off-road capability.
    • Typically requires exhaust modification. Iron Rock does have exhaust kits available for many models.
    • Installation difficulty is “hard.” Typically requires welding/cutting/drilling.

    First time buyer
    Location: Tennessee
    Date: August 9, 2018
    First off the 3 link flexes and controls road manners beautifully. The finish is also very nice, but... Bump stopping for a 31 inch tire allowed enough up travel for the upper arm to contact the front driveline yoke until caster was set to 8.5 degrees! I am now struggling with driveshaft vibs as i do not want to lift higher or run bigger tires at the moment. Another reviewer mentioned the Allen key being hard to get to is correct on that as well. If the upper arm had less bend it would still clean the floor but also the front yoke at full bump. I was in contact with them and their only advise was to adjust the pinion down...

    Been running this kit for about 7 months now. I love. It. It drives nice on the road and it flexes great. There are two issues that I do not like though. One Being you cannot tighten the upper driver side control arm collar over the flex joint with a ratchet. You have to use a small Allen wrench but you can't get it that tight. And two. The upper control on on the driver side hits the driveline when stuffing the driver side front tire up. It broke off my geeeze zerk on my front driveline and it's also putting a nice little rub spot in the metal on the control arm. I have pictures just not sure if I can post them on here.

    Solid build quality and great customer service. As a hobbyist mechanic, the install was challenging for me. The instructions will give you an idea if you need a professional install. I've wheeled it a few times now on black diamonds and it articulates easily, taking a lot of stress off of my XJ's chassis. Road manners are good, too. Buy with confidence.
