The Prothane red coil spring isolator is designed for 2004 and later Ford F-150 front coil springs used with 2.5in lift spacers. It cushions the spring-to-seat interface to reduce noise and metal-to-metal contact while supporting lifted front suspension geometry. This isolator helps maintain spring seating and reduces creaks for lifted F-150 front suspension installations matching the specified configuration.
