RockJock Antirock Rear Sway Bar Kit – Forged Arms, 1" Bar (2018+ Jeep Wrangler JL Unlimited 4-Door)
The RockJock Antirock Rear Sway Bar Kit with forged arms and 1" bar is a premium off-road performance upgrade for the 2018+ Jeep Wrangler JL Unlimited 4-Door. When used with a matching front Antirock sway bar, it provides balanced suspension performance for rugged off-road conditions by distributing weight and traction more evenly across all four tires.
The system replaces the stock sway bar with heavy-duty components for increased strength and articulation. The 50" x 1" bar is made from heat-treated SAE 4130 steel for maximum strength, while the forged 4140 chromoly arms and adjustable heim-jointed links ensure durability and precise tuning. The kit includes semi-gloss black powder-coated bolt-on steel frame brackets, Delrin frame bushings, and all necessary hardware for a straightforward installation.
The Antirock sway bar does not need to be disconnected for off-road use, though it will increase body roll compared to stock on the street. Proudly engineered for serious off-road enthusiasts.
