What It Helps Address

• Rear suspension clunking caused by worn stabilizer bar bushings
• Excess sway bar movement at the rear of the vehicle
• Loose or degraded rubber bushings from age and road exposure
• Noise and vibration transferred through the rear suspension
• Loss of consistent stabilizer bar support on OE-style setups

Installation Notes

Verify rear stabilizer bar diameter and vehicle application before installation. This kit does not include a bracket or grease fitting, so reuse or source any required mounting components separately. For best results, inspect the sway bar, brackets, and surrounding suspension hardware for wear before installing the new bushings.

Quality Assurance

Dorman designs this bushing kit as a direct OE replacement and subjects it to testing for fit and function on the listed applications. Part number 532-512 is built to match the original suspension interface on supported Infiniti and Nissan rear stabilizer bar setups.
