    4 inches of rock crawling, mud slinging fun, packaged together in a kit that won't break your bank. We include everything you need to lift your WJ 4 full inches, including quite possibly the strongest fully adjustable track bar on the market. It is made from 1.25 inch diameter solid cold rolled steel bar, and huge 7/8 inch diameter fine adjusting thread for the maximum in strength and fine adjustability. Many optional upgrades are available for the serious off road enthusiast. Improve your Jeep's off road ability and looks yet still ride in comfort as you command the pavement. We know this WJ is likely your daily driver so our kit was designed with excellent on road feel. Great looks, easy to install, and an unbeatable value price! 

    We have the most flexible sway bar links on the market. This means you get the most articulation available without having to remove the sway bar or the links.

JKS Quicker Disconnects are available and recommended as an optional upgrade for serious off roaders. Our transfer case drop is machined from 1 inch thick solid aluminum. The average offroader will enjoy the fact that the OEM control arms are a very durable fully boxed design.

    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.

    Bought this 4" lift for our WJ. It is a 2003 and the install instructions were spot on! We passed down our WJ to my 16 yo daughter. The original suspension was worn out. After talking to Patrick, I was assured this lift would be ok for my daughter. I ordered the kit and it showed up about a month later. I was missing a part and a quick call to Patrick got me my part in 4 days. Great service. After starting the install, I realized I had a wrong part. Another call to support (talked to Allen) and the wrong part was exchanged for the correct one in 3 days, with a return label for the wrong part. Now, before anyone says that there should not have been these delays, I challenge anyone to tell me they are perfect. But, how many companies can you get a live person on the phone right off? They made everything right at their expense. Great Customer service! Finished the install after receiving the part and following instructions, all measurements were on with only minor tweaking. The WJ drives tighter, feels better and the daughter loves it. I highly recommend IRO .

    Bought in 2020 because all my bushings were shot and I wanted to add some clearance to my 4.7 WJ. Went back and forth for months trying to price out my options and ended up getting this kit. Pros: • Simple install (just a pain in the butt) with no cutting or drilling, just simply remove and replace • Adds lift without changing profile • Quality is excellent Cons: (some common with SA) • DEATH WOBBLE! Standard alignment, ultra smooth and comfortable... until about 40 mph. IRO suggested specs, more speed without DW (up to 55), but the ride is much rougher and somewhat "squirrelly" driving. • Be ready for constant bolt checks, even with blue thread lock • To maintain pinion angle, had to lengthen wheelbase due to A-arm being "bottomed out" for adjustment • Noticable bump steer Overall, I'm glad I don't have to use the highway, but I do miss it. This is a good kit, but for the height, go with a Long Arm. My other WJ came with a ARB 2.5" SA lift, and I have had no issues other than clearance. I recommend this kit if it's not your daily driver, or if your a thrill seeker; but, otherwise, go lower or go long arm.
