Product Description

The RockJock RJ-183400-101 Johnny Joint Adjustable Rear Trac Bar is built specifically for the 2021-24 Ford Bronco platform, engineered to deliver improved rear axle stability, articulation and geometry control in both stock and lifted applications. With greasable Johnny Joint rod ends on both ends and a heavy-duty DOM tubing construction, it's designed for serious off-road performance while retaining on-road refinement.

The adjustable nature of the trac bar enables installers to center the axle under the chassis and improve driveshaft clearance, particularly useful when running larger aftermarket differentials or upgraded rear suspension components. The bar comes finished in corrosion-resistant powder coat and features a gold-zinc plated adjuster, designed for durability in demanding environments.

Installation is straightforward for the Bronco rear suspension - no complete fabrication required when used with factory mounting points - and the design accommodates lifted setups (up to 45.160" length) while maintaining robustness for trail or overland use. Always verify clearance with aftermarket exhaust or adjustable rear control arms prior to installation.
