Installation Notes and Tips

Verify the stabilizer bar diameter before installation; this application is for a 24 mm bar. Inspect the mounting area for wear, corrosion, or deformation before installing the new bushings. Because the bracket is not included, reuse the existing bracket if it is serviceable and within specification. Confirm the front-to-frame position on the vehicle before ordering or installing Dorman 540-621.
