What This Part Helps Address

• Reduced rear suspension stability from deteriorated rubber bushings
• Noise caused by cracked, hardened, or compressed bushings
• Uneven bar movement during cornering and road input

Installation Notes

Verify the rear stabilizer bar diameter before installation, especially on the 2014-2015 INFINITI Q60, which lists a 23 mm diameter bar. Inspect the stabilizer bar and mounting surfaces for wear or corrosion before fitting the new bushings. Because no bracket is included, reuse the existing hardware only if it is serviceable and matches the application.
