RockJock Universal 36" Sway Bar AntiRock Kit w/ Steel Arms
ROKCE-9901-17
The RockJock Universal AntiRock Sway Bar Kit with Steel Arms from RockJock Off Road is a rugged, proven solution for custom rigs, rock buggies, and fabricated suspensions where durability and predictable off-road control are the priority.
AntiRock sway bars are engineered to keep the front and rear suspension working together in uneven terrain, improving traction and stability with no disconnects required. This is a true fabricator style universal kit that includes everything needed for installation except the welder.
This kit features a 36-inch, .770-inch diameter heat-treated chromoly torsion bar, paired with fabricated steel sway bar arms available in 17 in., 18 in., 20 in., or bent 20 in. lengths. Adjustable end links, Delrin bushings, weld on axle tabs, and a complete hardware pack provide the flexibility needed to dial in leverage, stiffness, and fitment for a wide range of builds.

Tech Insight
The .770-inch torsion bar offers a balanced AntiRock rate well-suited for mid-to-heavy-weight rigs and higher-speed trail use. Steel arm length selection allows fine-tuning of effective stiffness:
17 in. arms: Firmest effective rate, compact packaging
18 in. arms: Balanced performance for most builds
20 in. arms: Softer effective rate, increased articulation
Steel arms are ideal for aggressive trail use, competition, or builders who prioritize long-term durability over weight savings.
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; alternate lengths available depending on lift height
