Advanced Suspension Technology bushings offer a unique polyurethane alternative to conventional rubber suspension bushings.

AST bushings are urethane-based and are impregnated with graphite to aid in lubrication and reduce noise.

Polyurethane bushings are stronger and last longer than standard rubber bushings. Most modern production vehicles are designed using rubber bushings which have a limited lifespan. This contributes to suspension failure due to vehicular weight and the inherent design of high-tech suspensions. Typically this results in less than desirable vehicle handling and can cause many related parts to wear out more rapidly than necessary. Polyurethane corrects this problem and in many cases improves vehicle handling and drivability.

Once removal of original bushings has taken place, installation of the new polyurethane bush typically takes from 1 – 5 minutes to install.

Features and Benefits:

• Unique polyurethane alternative
• Sleeves in the bushings freely rotate which enhances longevity
• Impregnated with graphite to aid in lubrication and reduce noise
• Alternative to conventional rubber suspension bushings
