The RockJock Universal AntiRock Sway Bar Kit from RockJock Off Road is built for custom rigs, buggies, and fabricated suspensions that need predictable balance and consistent traction off-road without ever disconnecting a sway bar.

AntiRock systems help keep front and rear suspension working together in uneven terrain, improving control and confidence. This fabricator style universal kit includes nearly everything required to install an AntiRock system on your build you supply the welder.

At the core is a 36-inch, .770-inch diameter heat-treated chromoly torsion bar, paired with 20-inch billet aluminum sway bar arms for increased leverage and tuning range. Adjustable end links, Delrin bushings, weld on axle tabs, and a complete hardware pack round out a kit designed to be adaptable as your build evolves.

Tech Insight

AntiRock tuning is driven by bar diameter and arm length. The .770-inch bar offers a firmer effective rate than smaller-diameter options, making it well-suited for heavier rigs or higher-speed trail use. The included 20-inch aluminum arms increase leverage, softening the effective rate and providing added articulationgiving builders a broad tuning window without swapping the entire system.
