Pre-Runner Antirock Kits
RockJock’s Pre-Runner Antirock Kits are engineered for high-speed off-road and long-travel suspension builds, delivering a balance of stability, durability, and controlled articulation for racing and custom 4×4 applications. To ensure your custom installation meets safety and performance standards, please consult our Instruction Manuals.
Pre-Runner Antirock Features
- 35-Spline Torsion Bars – Heavy-duty bars designed to handle high loads, long-travel suspension cycles, and aggressive off-road use.
- Multiple Bar Lengths – Available in various lengths (such as 45", 47", 50") to suit different chassis widths and custom frame designs (bars may be trimmed to fine tune length).
- Pre-Runner Style Arms – billet aluminum arms engineered for strength, leverage, and high-speed stability.
- High-Durability Bushings – Low-friction, wear-resistant bushings built for smooth articulation under sustained load.
- Fabrication-Ready Components – Designed for custom mounting, link placement, and geometry tuning rather than bolt-on installation.These specialized components can be sourced through a professional shop via our Dealer Locator.
Fitment
- Intended for custom-built, long-travel, and high-speed off-road vehicles such as Pre-Runners, desert racers, rock buggies, and custom 4×4s.
- Not vehicle-specific; fitment depends on chassis width, suspension geometry, and fabrication design.
- Installation requires welding and fabrication experience to properly mount the sway bar, arms, and end links.
- Suitable for off-road–focused builds and mixed-use rigs where a permanent, heavy-duty sway-bar solution is preferred.
