RockJock AntiRock Front Bushing for TJ / LJ
ROKCE-99004
This AntiRock Sway Bar Bushing from RockJock Off Road is a TJ/LJ front specific bushing engineered to fit directly into the factory front frame crossmember tube on TJ Wrangler and TJ Wrangler Unlimited (LJ) models.
Unlike standard AntiRock bushings, this unit features a unique machined profile with a flat that allows for proper alignment and easier installation in the TJ/LJ front crossmember. CNC machined from billet black Delrin, it delivers squeak-free operation, excellent wear resistance, and long service life, even under hard trail use.
This bushing accepts any RockJock 25-spline AntiRock torsion bar, regardless of center diameter, making it ideal for replacements, rebuilds, or spare parts on TJ/LJ front AntiRock systems.

Tech Insight
TJ and LJ front AntiRock systems require a dedicated bushing design due to the factory crossmember tube geometry. This bushing’s machined flat ensures proper clocking and press fit—something a standard AntiRock bushing cannot provide. As with all AntiRock systems, sway bar tuning is achieved by changing torsion bar diameter, not the bushing.
