Tech Insight
Fine-Tune Body Roll and Articulation
The five end link mounting holes allow you to easily adjust sway bar leverage. Mounting the end links closer to the torsion bar increases sway bar stiffness for improved on-road handling, while moving them farther out softens the effective rate to increase suspension articulation on the trail.
Built for Real Off-Road Abuse
Unlike lightweight aluminum arms, these fabricated steel arms are designed for maximum durability in harsh rock crawling environments where repeated impacts, high suspension loads, and severe articulation are common.
Perfect for Repairs or Custom Builds
These arms are ideal as direct replacements for damaged RockJock AntiRock arms or as the foundation for custom sway bar installations utilizing a 25-spline AntiRock torsion bar. Their laser-cut construction ensures consistent dimensions and accurate end link positioning for predictable suspension tuning.
