What material is this bushing made from and why does it matter?

This bushing is made from UHMW (Ultra-High Molecular Weight) plastic. This material is chosen for its low friction and high wear resistance, which helps ensure smooth operation and longevity for the sway bar support.

Does this bushing come with the sway bar itself?

No, this is a single frame bushing for the left rear bracket. It is designed to be used with a RockJock Antirock sway bar kit that includes a 28-spline bar.

How does this bushing support the Antirock sway bar?

The bushing knocks into the stock frame tube and provides a stable mounting point for the Antirock torsion bar. This support is crucial for the sway bar to effectively control body roll during turns.

About this part

Product Details

This UHMW frame bushing is specifically made for the left rear frame bracket on your 2018-2025 Jeep Wrangler, designed to work with RockJock's Antirock sway bar kits that use a 28-spline bar. It knocks into the stock JL frame tube and provides a solid support for the Antirock torsion bar, which is key to how the system manages body roll.

The Ultra-High Molecular Weight (UHMW) plastic used for this bushing is known for its low friction and excellent wear resistance. This means it will smoothly support the sway bar's movement over time, helping to maintain consistent handling characteristics. It's a direct replacement part for the bushing found in RockJock's rear Antirock kits, ensuring it fits right where it needs to.
