The RockJock Universal AntiRock Sway Bar Kit from RockJock Off Road is designed for custom rigs, buggies, and fabricated suspensions that require increased roll control while maintaining excellent off-road articulation.

AntiRock sway bars balance front and rear suspension movement on uneven terrain, improving traction and stability without the need for manual disconnects. This universal fabricator kit includes nearly everything needed for installation and you supply the welder.

At the core of this system is a 45 inch, .800 inch diameter heat treated chromoly torsion bar, paired with either 18 inch or 20 inch billet aluminum sway bar arms to provide leverage and tuning flexibility. Adjustable end links, Delrin bushings, weld on axle tabs, and complete hardware ensure the kit can be tailored to a wide range of custom applications.

Tech Insight

The .800-inch torsion bar provides a firmer AntiRock rate ideal for heavier vehicles, rear sway bar applications, or higher speed off-road use. The aluminum arms increase leverage, helping fine tune effective stiffness and maintain articulation. This combination makes the 45 inch universal kit a popular choice for rear installations on stretched wheelbase rigs and custom buggies.

Important Notes:

• Installation: Welding required; universal fabricator kit
• Body Roll: Increased body roll compared to factory sway bars
• Street Use: Street drivable, but handling characteristics differ from OEM sway bars
• End Links: Long thread links can be trimmed; alternate lengths available
