Product Details

What It Helps Address

• Clunking or rattling from worn stabilizer bar bushings
• Excessive sway bar movement at the frame mount
• Loose or degraded rubber at the front suspension attachment point
• Noise during cornering or over uneven pavement
• Loss of stabilizer bar support on front-to-frame applications

Installation Notes

Verify bar diameter before installation, since listed fitments include 36 mm and 33 mm stabilizer bar applications. Confirm the vehicle year, make, model, and front-to-frame mounting location before ordering. Professional installation is recommended for proper suspension service and alignment of the bushing at the sway bar mount.

Quality Assurance
