Product Description

The RockJock RJ-246203-101 is a bolt-on Antirock rear sway bar kit built for the JL Wrangler and Wrangler Unlimited, using forged arms and a heavy-duty 1 in. diameter bar for serious off-road articulation. Unlike a factory sway bar that typically needs to be disconnected for maximum trail flex, RockJock's Antirock design stays connected at all times while still allowing the suspension to fully articulate - helping keep traction balanced across all four tires without sacrificing on-road stability.

The 50 in. x 1 in. bar is made from SAE 4130 heat treated steel, the same grade used in professional off-road competition sway bars, and pairs with forged sway bar arms and bolt-on steel frame brackets finished in a durable semi-gloss black powder coat. Installation replaces the factory rear sway bar directly using hand tools, with no welding or frame cutting required.

For best results, RockJock recommends pairing this rear kit with a matching front Antirock sway bar kit, since running Antirock on both ends of the vehicle is what delivers the full balanced front-to-rear articulation the system is designed around. Builders running non-stock frame widths or wheel/tire combinations should also check clearance and frame-width fitment notes before installing.
