The RockJock AntiRock Front Sway Bar Kit is a bolt on front sway bar system for TJ Wrangler and TJ Wrangler Unlimited (LJ) platforms. Designed to replace the factory front sway bar, AntiRock systems dramatically improve articulation and off-road traction with no disconnects required.

Built around a .770-inch, 4340 heat treated chromoly torsion bar, this kit balances trail performance with predictable control. Forged chromoly sway bar arms deliver strength and durability, while Delrin frame bushings provide quiet, squeak free operation and long service life. Adjustable end links allow you to dial in geometry for your lift height and suspension setup.

Everything required for installation is included.
