Rock Krawler Suspension JL25UA-2 2.5 Inch Ultimate Adventure Mid-Arm Lift System

The Rock Krawler JL25UA-2 is a complete 2.5-inch Ultimate Adventure Mid-Arm suspension system specifically designed for Jeep Wrangler JL owners seeking a bolt-in installation with exceptional articulation and performance. This comprehensive lift kit combines superior on-road comfort with aggressive off-road capability, delivering the durability and performance Rock Krawler is known for.

Complete Control Arm System:

The Ultimate Adventure System includes four non-adjustable lower control arms and four fully adjustable upper control arms, all equipped with 100% service-free Adventure Series joints. The fixed lower control arms provide 70 degrees of misalignment to reduce binding, while the adjustable upper arms allow precision tuning of caster angle in the front and pinion angle in the rear.

Triple-Rate Coil Spring Technology:

Rock Krawler's industry-leading triple-rate coils deliver 2.5 inches of lift to accommodate up to 38-inch tires (depending on model) while improving on-road ride quality over factory linear-rate springs. The coils are built with proper free-length for maximum off-road articulation and remain firmly seated in the coil bucket, providing controlled response to bumps, rocks, sand, and mud.

Geometry Correction Components:

• Correction pads to reduce factory spring bow
• Front and rear track bar geometry corrections for perfectly centered axles
• Service-free control arm joints using innovative technology
• High-misalignment joints at frame and axle connections

This mid-arm system provides an optimal balance between performance and ease of installation, making it ideal for Wrangler owners who demand the best articulation without the complexity of a long-arm system. Whether you're commuting on the street, towing, or tackling challenging trails, the JL25UA-2 delivers exceptional geometry and ride quality.
