The Delphi TD4662W Coil Spring Insulator is engineered to provide a reliable solution for maintaining suspension integrity in various vehicle models. Designed for the front upper position, this insulator measures 5.43" in both inside and outside diameters, with a thickness of 0.79". Constructed from durable rubber, it effectively cushions the coil spring, reducing noise and preventing direct metal-to-metal contact, thereby extending the lifespan of suspension components. This insulator is compatible with a range of vehicles, including select Ford Ranger models from 1998 to 2011, and Mercury Grand Marquis models from 1980 to 2002. By choosing the Delphi TD4662W, fleet operators can ensure consistent vehicle performance and minimize maintenance downtime.
