RockJock Universal AntiRock 32" Sway Bar Kit
ROKCE-9903A-18
The RockJock Universal AntiRock Sway Bar Kit gives builders a complete starting point for adding a torsion-style sway bar to a custom buggy, rock crawler, Jeep, or fabricated suspension system. Unlike a disconnect-style sway bar, the AntiRock is designed to remain connected on and off the trail, helping balance suspension movement while still allowing the axle to articulate over uneven terrain.
This universal fabricator kit uses a 32" long, .700" diameter heat-treated chromoly torsion bar with your choice of 18" or 20" billet aluminum arms. RockJock includes the mounting tube, adjustable end links, Delrin bushings, weld-on axle tabs, and installation hardware, giving the builder the components needed to package the AntiRock around the vehicle's chassis and suspension geometry.

- (1) 32" x .700" Heat-Treated Chromoly Torsion Bar

- (2) 18" or 20" Billet Aluminum Sway Bar Arms
- Adjustable Sway Bar End Links
- Delrin Sway Bar Bushings
- Weld-On Axle Tabs
- Installation Hardware
- Arm Stickers
Arm Length Options:
- 18" Arms

Fitment
Common Applications:
- Rock crawlers
- Off-road buggies
- Custom tube chassis vehicles
- Modified Jeeps and trail rigs
- Fabricated 4-link suspension systems
- Custom front or rear sway bar installations
Fitment Notes:
- Universal fabricator kit; not a vehicle-specific bolt-in sway bar.
- Welding and fabrication are required for installation.
- Verify available chassis width and packaging for the 32" torsion bar and 30" mounting tube.
- Plan sway bar arm clearance through the complete suspension travel before final installation.
- End-link mounting points should be positioned around the vehicle's suspension geometry and available axle clearance.
- Long-thread end links can be trimmed as required for the installation.
FAQ
Does the RockJock AntiRock need to be disconnected for off-road use?
No. The AntiRock system is designed to remain connected during both on-road and off-road driving while allowing controlled suspension articulation.
What is the difference between the 18" and 20" sway bar arms?
Arm length changes the leverage applied to the torsion bar. The longer 20" arm provides more leverage and a softer effective rate than an 18" arm when the remaining mounting geometry is the same. Final arm selection should also account for chassis packaging, end-link location, and suspension geometry.
Is this RockJock AntiRock kit a bolt-on installation?
No. This is a universal fabricator kit intended for custom installations. Welding and fabrication are required to position the mounting tube, axle tabs, sway bar arms, and end links around the vehicle.
Can the AntiRock be used on the street?
The AntiRock can remain connected for on-road driving, but vehicle handling and body roll will differ from a factory sway bar system. Drivers should become familiar with the vehicle's handling characteristics after installation.
What should I check before installing a universal AntiRock sway bar?
Check available chassis width, torsion bar and mounting tube placement, arm clearance, end-link location, axle movement, and surrounding suspension components through the full range of travel before completing final welding.
