Use a compatible W21301 or KBR10 universal mounting bracket for the intended installation.

The package contains two mount bushings for one sway bar mounting location pair.

What does the knurled inner bore do?

The knurled inner bore is designed to help retain grease around the sway bar during service.

What material are the bushings made from?

They use a synthetic elastomer formulation and have a black finish.

How long does installation take?

Whiteline lists an installation time of about one hour. The actual time depends on vehicle access and the condition of the existing mounting hardware.

What warranty is included?

Whiteline backs the bushings with a limited lifetime warranty. Review the current warranty terms before installation.

Installation Instructions

  1. Confirm that the sway bar measures 25 mm and that the mounting bracket is compatible with the bushing profile.
  2. Park the vehicle on a stable level surface, apply the parking brake, and support the vehicle safely if access requires lifting.
  3. Remove the existing sway bar mount hardware and retain the fasteners only if they are serviceable and specified for reuse.
  4. Clean the sway bar and mounting surfaces, then inspect the bar for damage, corrosion, or wear that could prevent proper seating.
  5. Apply suitable grease to the bar and position one bushing around the bar with the flange seated against the mounting structure.
  6. Install the compatible universal saddle or bracket and repeat the process on the other mounting location.
  7. Install the hardware and tighten it to the vehicle or bracket manufacturer's specified torque.
  8. Check that both bushings are seated evenly and that the sway bar moves without binding before lowering the vehicle.
  9. After a short road test, recheck the mounting area for movement, noise, or loose hardware.
