The Prothane motor mount insert for 1984–1997 Chevy Astro and S-10 4.3L applications replaces the factory insert to restore mount geometry and reduce engine movement. This red insert is a direct-fit replacement that helps stabilize the motor in vehicles with the 4.3L setup, reducing vibration and improving driveline steadiness during normal and spirited driving.
