This 12-piece kit replaces the stock front suspension plastic bushings with metal Oilite® bushings. Made of a copper/iron alloy impregnated with an oil lubricant (self-lubricating) commonly used in industrial and high performance bearing applications. These bushings drastically improve wear. Consumers have reported 10 times longer bushing life with these Oilite® bushings versus stock plastic bushings. Due to the material nature of metal versus plastic, one can construct the bushing too much tighter tolerances, which translates into less free play/unwanted movement in your front suspension. These bushings also offer a higher resistance to harsh operating condition changes including temperature and moisture which equates to a longer lasting, more durable bushing. Includes: Upper Inner A-Arm (4); Lower Inner A-Arm (8).
