Optimize Axle Alignment with the RockJock Johnny Joint Rear Trac Bar

Enhance your 2021 and newer Ford Bronco's suspension performance with the RockJock Johnny Joint Adjustable Rear Trac Bar. This meticulously engineered component is designed to provide precise axle centering and improved clearance, whether your Bronco is stock or lifted. Featuring RockJock's renowned Johnny Joint rod ends, this trac bar offers maximum articulation and durability for all your off-road adventures.

Precision Engineering for Optimal Fit and Function

The adjustable design allows you to fine-tune your axle's position, ensuring it remains perfectly centered under the chassis. This not only improves handling but also increases clearance between your driveshaft and fuel tank, a critical consideration for lifted vehicles or those with larger differentials. The trac bar is fabricated from high-quality 1 3/8 in. x .120 in. wall DOM tubing, ensuring strength and resilience.

Superior Articulation and Durability

Equipped with greasable, narrow Johnny Joint rod ends at both the axle and chassis mounting points, this trac bar allows for exceptional suspension travel and articulation. The adjustable end at the axle housing provides the necessary range for precise alignment. The bar is finished in a durable semi-gloss black powder coat, with the Johnny Joint adjuster end featuring gold zinc plating for corrosion resistance.

Key Features:

  • Adjustable for precise axle centering on 2021+ Ford Broncos.
  • Features greasable, narrow Johnny Joint rod ends for maximum articulation.
  • Constructed from 1 3/8 in. x .120 in. wall DOM tubing.
  • Durable semi-gloss black powder coat finish.
  • Improves driveshaft-to-fuel-tank clearance.
  • Can be used with or without the RJ-181400-101 Trac Bar Relocation Bracket.

Upgrade your Bronco's suspension with a component built for performance and reliability. The RockJock Johnny Joint Adjustable Rear Trac Bar is the ideal solution for enthusiasts seeking superior axle control and articulation. Get yours today at GGCRACING.
