Product Description

The RockJock CE-9900YJF Antirock Front Sway Bar Kit is engineered precisely for the 1987-1995 Jeep Wrangler YJ to enhance front suspension performance in lifted or high-articulation off-road setups. By replacing the factory sway bar with a carefully tuned torsion bar system constructed from 4130 chromoly steel, this kit gives your vehicle improved axle articulation and consistent traction while maintaining front-end stability.

Installation is straightforward for the YJ chassis, though it does require welding the supplied tabs to the axle housing and minor trimming of the right inner fender panel for arm clearance. Once installed, the adjustable end links allow you to dial in the system for around a 4" lift or other custom heights. The result is a front suspension that stays connected and controlled - whether you're carving trails or cruising the pavement.

This kit is ideal for off-road enthusiasts, rock-crawlers and anyone running a lifted YJ who wants dependable sway bar performance without the hassle of quick-disconnects or drop links. Fitment is confirmed through 1995; coverage for later models (1996-on) is unconfirmed at time of listing.
