Born from the long lineage of the IRO long arm tradition. Look no further for the best performing long arm lift kit for the JL Wrangler, the Rock-Link PRO 4" lift kit.
Experience your Wrangler, refined. It's a Jeep, but that doesn't mean it has to ride like a lumber wagon. The Rock-Link PRO 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 PRO lift kit delivers a true ride quality improvement for your daily driver that you can be proud of. Are you tired of your JL tracking wildly down the highway? The built in adjustments will give you everything you need to dial it in to perfection. Even stock, JL'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 JL platform. We learned that the biggest improvement in ride quality and off road performance comes with a FRONT and REAR long arm system. When looking at what this Rock-Link PRO offers versus the cost, we challenge you to find a suspension system that will take your Wrangler Beyond Boundaries at a price that is even close.
Note: Rubicon models use 1in taller springs from the factory. This kit will net 3in of lift on Rubicon models.
