Dorman 540-751 Stabilizer Bar Bushing Kit

Dorman 540-751 is a standard replacement suspension stabilizer bar bushing kit built for specific vehicles with a 20 mm front-to-frame sway bar.

• Fits vehicles with a 20 mm diameter stabilizer bar
• Bracket not included

Detailed Description

This Dorman suspension stabilizer bar bushing kit is made to match the original equipment design for select GM and Saturn platforms. The 540-751 part number is used on front-to-frame applications where the stabilizer bar measures 20 mm in diameter, including 2004-2008 Pontiac Grand Prix and 2005-2009 Buick Allure, Buick LaCrosse, Chevrolet Uplander, Pontiac Montana, Buick Terraza, and Saturn Relay. It also cross-references MOOG Chassis Products K80812 for the same application.

What It Helps Address

• Clunking or rattling from worn sway bar bushings
• Excess stabilizer bar movement at the frame mount
• Loose or degraded rubber bushings from age and road exposure
• Front suspension noise during turns and uneven-road driving
• Reduced stabilizer bar support at the mounting point

Installation Notes and Tips

Verify the stabilizer bar diameter before ordering; this kit is specified for a 20 mm bar. Confirm the front-to-frame mounting location and compare the original bushing dimensions to the Dorman 540-751 replacement before installation. Clean the mounting surface and inspect the stabilizer bar and brackets for wear or damage that could affect bushing performance.

Quality Assurance

Dorman states that this bushing kit is precision-engineered and rigorously tested to provide a reliable replacement for the original equipment on specific vehicles. The standard replacement design supports direct-fit service on the listed applications.
