The AntiRock sway bar torsion bar from RockJock Off Road is a standalone torsion bar designed for builders tuning or assembling a custom AntiRock sway bar system. It is forged and heat-treated from 4340 chromoly for maximum durability.

AntiRock torsion bars are offered in multiple lengths and diameters to fine tune sway bar rate as vehicle weight, suspension geometry, and intended use evolve. Bar diameter directly affects stiffness with larger center diameters increase roll resistance, while smaller diameters provide a softer, more compliant ride when bar length remains the same.

This specific bar measures 32 inches tip to tip and features a .700-inch center diameter with standard 1-inch OD ends and 25 splines, making it a versatile choice for classic Jeep CJ front applications and Side by Side rear setups.

Tech Insight

AntiRock torsion bars allow precise tuning of sway bar stiffness without changing arms or links. A .700-inch center diameter offers a balanced rate ideal for lightweight rigs, classic CJ platforms, and rear UTV applications where articulation and stability are equally important. As builds evolve, swapping to a larger or smaller diameter bar is the easiest way to fine-tune handling without reworking the entire system.
