The RockJock Universal AntiRock Sway Bar Kit with Steel Arms from RockJock Off Road is a proven, no-nonsense solution for custom rigs, buggies, and fabricated suspensions that demand durability and predictable off-road performance.

AntiRock sway bars are designed to keep the front and rear suspension working together in uneven terrain, improving traction and control without ever needing to disconnect. This universal fabricator kit includes nearly everything required to install an AntiRock system on your vehicle and you supply the welder.

At the heart of the kit is a 32-inch, .700-inch diameter heat-treated chromoly torsion bar, paired with your choice of fabricated steel sway bar arms in 17", 18", or 20" lengths. Adjustable end links, Delrin bushings, weld-on tabs, and a complete hardware pack make this kit easy to tailor to your specific suspension geometry and vehicle weight.

Tech Insight

This kit is tuned around a .700-inch torsion bar, offering a compliant, crawler-friendly AntiRock rate ideal for lightweight to mid-weight rigs.

Steel arms provide maximum durability for hard trail use, while arm length selection allows builders to fine-tune leverage:

• 17 in. arms: Firmer effective rate, tighter packaging
• 18 in. arms: Balanced all-around performance
• 20 in. arms: Softer effective rate, increased articulation

Important Notes

• Installation: Welding required; universal fabricator kit
• Body Roll: Increased body roll compared to factory sway bars
• Street Use: Street-drivable, but handling differs from OEM sway bars
• End Links: Long-thread links can be trimmed to fit your application; alternate lengths available depending on lift height
