The RockJock Universal AntiRock Sway Bar Kit from RockJock Off Road is built to balance front and rear suspension during off-road use, delivering more consistent traction without ever needing to disconnect. This universal kit includes nearly everything required to install an AntiRock system on your vehicle while all you need to bring is the welder.

At the core of the kit is a 32-inch, .700 diameter heat treated chromoly torsion bar, paired with your choice of 18-inch or 20-inch billet aluminum sway bar arms. Adjustable end links, Delrin bushings, weld-on tabs, and complete hardware are all included, giving builders maximum flexibility to dial in leverage, rate, and fitment for their specific suspension geometry.

Tech Insight

AntiRock systems are tuned by bar diameter and arm length. The included .700 bar provides a compliant, crawler-friendly rate, while the choice between 18 or 20 aluminum arms allows builders to fine-tune leverage. Longer arms reduce effective stiffness and increase articulation, making this kit especially versatile as vehicle weight, suspension, or driving style evolves.

Installation: Welding required; not a bolt-in kit

Body Roll: AntiRock-equipped vehicles will have more body roll than factory sway bars

Street Use: May be driven on-road, but handling differs from factory sway bars

End Links: Long-thread links can be trimmed to fit; alternative lengths available depending on lift height
