What is a Johnny Joint and why is it greasable?

A Johnny Joint is a type of rod end that allows for a significant amount of movement, which is great for off-road articulation. Being greasable means you can inject grease into it, helping to keep it lubricated and extending its lifespan.

Does this track bar come with all the necessary hardware for installation?

This track bar includes the urethane bushing and the Johnny Joint rod end with its jam nut. It is designed as a bolt-on replacement for the factory track bar.

What is the benefit of an adjustable track bar?

An adjustable track bar allows you to center your rear axle under your Jeep, especially after lifting it. This helps to correct axle shift and ensures proper suspension geometry for better handling and tire clearance.

About this part

Product Details

When you're working on the rear suspension of your Jeep Wrangler JK, this adjustable track bar from RockJock is a solid option for improving its performance. It's designed to replace the stock unit and offers a more robust solution for handling lifted suspensions or just for getting better articulation on the trail. You get the main track bar arm, a heavy-duty urethane bushing for the frame mount, and a forged Johnny Joint rod end with a jam nut for the axle side.

The arm itself is built from 1.250 inch outer diameter, .250 inch wall 4130 chrome moly steel tubing. This is a strong material that can handle the stresses of off-roading. The Johnny Joint rod end is a 1-inch right-hand thread, 2-inch diameter unit that's greasable, meaning you can easily service it to keep it moving freely. It's finished in a semi-gloss black powder coat to resist corrosion, and the Johnny Joint end has a gold zinc plating.

This track bar is adjustable, allowing you to fine-tune your rear axle's positioning, which is especially helpful if you've modified your suspension. It's designed as a bolt-on part, making installation straightforward for most DIYers.
