Rock Krawler JK25AS-2 2.5" Adventure Mid-Arm System Suspension System without Shocks for 07-18 Jeep Wrangler JK 2-Door
Solid Steel Front Track Bar: Unlike hollow factory units, this kit features a 1.5" O.D. solid steel adjustable front track bar. This provides the lateral stiffness required to keep the axle perfectly centered and prevents the "side-to-side" shimmy often felt over bumps.
Triple-Rate Coil Springs: These springs are specifically tuned for the JK’s weight distribution. They provide a plush initial ride for daily driving while offering a progressive rate that prevents the Jeep from "diving" under braking or sagging when loaded with trail gear.
Maintenance-Free "Pro Flex" Joints: These arms use Rock Krawler’s proprietary joints which are silent and 100% service-free. They provide significantly more articulation than stock bushings without the need for constant greasing or rebuilding.
"Abuse It" Lifetime Warranty: Rock Krawler provides a lifetime warranty on all hard parts (control arms and track bars). If you manage to bend or break a component while off-roading, they will replace it, making this a very secure long-term investment for your JK.
Many states have laws that limit the maximum height of a lifted vehicle. Never exceed the legal height limit.
The Rock Krawler 2.5" Adventure Mid-Arm System for the Jeep Wrangler JK is the premier entry-point for owners who want a "no-compromise" daily driver that can still tackle technical trails on the weekend. Specifically engineered for the JK’s unique geometry, this system focuses on correcting the caster angle—the most common cause of "flighty" steering and front-end instability—by including heavy-duty, adjustable front lower control arms. This ensures that even at highway speeds, your Jeep tracks straight and feels more planted than it did from the factory, even with larger tires.
The heart of this system lies in its premium components, featuring Triple-Rate Coil Springs that are tuned to provide a plush ride over small road bumps while offering a progressive rate to handle heavy aftermarket armor or winches. Unlike many budget kits that leave your axles off-center, this system includes a heavy-duty adjustable front track bar made from solid steel, allowing you to perfectly center your front axle and eliminate the lateral shift caused by the lift. It is a "bulletproof" foundation that allows for a low center of gravity (LCOG) build while providing the durability Rock Krawler is famous for.
