                Experience your Jeep refined. It's a Jeep, but that doesn't mean it has to ride like a lumber wagon. The Rock-Link delivers an instant seat of the pants improvement in ride quality. But that's not all! Out on the trail, the improvement in ride quality translates to a more enjoyable off road experience. The longer arms in this system link your axle to the frame at a much lower operating angle than short arms at the same lift height. By decreasing that angle and increasing the length of the arms, the impact of the terrain is more easily absorbed by the suspension. These improvements over short arms greatly reduce the transmission of shock loads though the frame causing discomfort in the driver's seat, and reduces accelerated wear and stress on other suspension components. Longer arms allow for huge articulation over larger obstacles while keeping the axle centered in the fender openings. This articulation keeps your tires on terra firma, which translates into more traction. When comparing an otherwise equally equipped vehicle that has short arms, the Rock-Link equipped one will take you farther.

                This kit is not just for rock crawlers! Maybe you aren't going to tackle Chocolate Thunder or Pritchett Canyon, but you are going to crush the REI parking lot, or turn every head while pulling up to your kid's campout. This Rock-Link upgrade delivers a true ride quality improvement for your daily driver that you can be proud of. Are you tired of your JK tracking wildly down the highway? The built in adjustments will give you everything you need to dial it in to perfection. Even stock JK's are setup with minimal caster from the factory, so get your alignment right once and for all with the Rock-Link.

                At IRO, we have been perfecting long arm systems since 2004, making them even better with each new product release. We have learned that subtle changes to the geometry will make significant improvements to your driving experience. We have applied all these important refinements to the JK platform. We learned that the biggest improvement in ride quality and off road performance comes with a FRONT long arm system. When looking at what this Rock-Link upgrade offers versus the cost, we challenge you to find a suspension upgrade that will take your JK Beyond Boundaries at a price that is even close.

                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

                • 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.

                • 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.
                • 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.
