RockJock CE-9906-21 Universal Antirock Sway Bar Kit 50x1in Bar 21in Steel Arms

Vehicle Fitment

• Universal - Designed for custom rigs, rock buggies, and any off-road build requiring a fabricated Antirock sway bar installation with a 50 in. x 1 in. torsion bar and 21 in. steel arms

Fitment Notes

• Universal fit - this is a fabricator kit and is NOT a bolt-in application; welding is required for installation
• The 21 in. steel arms included (RJ-232200-101) are the same arms used in RockJock's Jeep JK Wrangler 4-Door rear Antirock kits - suitable as a direct replacement or for custom builds requiring this arm length
• End link rods include long threads and can be trimmed to suit the specific lift height and application; alternative length end links are available separately if needed
• Antirock sway bars will exhibit more body roll than factory sway bars - this is normal and expected behavior; they may be used on street but do not replicate factory handling characteristics
• Antirock sway bars do NOT require disconnecting for off-road use

Features

• 4340 heat-treated chromoly 50 in. x 1 in. diameter torsion bar - the same material grade used in professional off-road competition sway bars
• 21 in. fabricated steel sway bar arms (RJ-232200-101) feature a slight outward tip bend and a single end link mounting hole for clean integration with the included end links
• Antirock design balances front and rear suspension articulation simultaneously - improves traction by distributing vehicle weight evenly across all four tires during off-road use
• No disconnecting required - Antirock sway bars allow maximum suspension articulation without the need to manually disconnect links on the trail
• UHMW sway bar bushings provide smooth, low-friction torsion bar rotation within the mounting tube
• Weld-on axle tabs included for custom end link mounting at the axle housing
• Adjustable end link rods feature LH and RH thread for easy length tuning without full disassembly
• Complete kit - includes all components needed for installation except a welder

Product Description

The RockJock CE-9906-21 is a universal Antirock sway bar kit built for fabricators constructing custom off-road rigs, rock buggies, and purpose-built crawlers. It pairs a 50 in. x 1 in. diameter 4340 heat-treated chromoly torsion bar with 21 in. fabricated steel sway bar arms - the same arm length used in RockJock's Jeep JK Wrangler 4-Door rear Antirock application. The Antirock design works by linking the front and rear suspension through the torsion bar, allowing one side to droop while the other compresses, which keeps all four tires planted and loaded on uneven terrain without requiring the driver to disconnect anything.

The kit includes the 48 in. DOM mounting tube, UHMW bushings, weld-on axle tabs, adjustable 14 in. end link rods, and all required hardware - everything needed to complete the installation except welding equipment. End link rods feature LH and RH thread for easy length adjustment and can be trimmed shorter to suit specific lift heights. This kit requires fabrication for mounting; it is not a direct bolt-in application.
