Detailed Description

This Mevotech coil spring insulator is used at the front lower spring seat to help isolate the coil spring from the suspension perch. By maintaining proper spring contact and reducing metal-to-metal contact, it supports quieter operation and more consistent suspension geometry on vehicles such as the 2000-2011 Chevrolet Impala, 2000-2007 Chevrolet Monte Carlo, 1997-2004 Buick Regal, and 1997-2003 Pontiac Grand Prix. The corrosion-resistant finish adds protection in exposed underbody locations, making MP904943 a practical replacement during front suspension service.

This part cross-references Monroe Shocks & Struts 904943 for the same application.
