Prothane 84-97 Chevy Astro/S-10 4.3L Motor Mount Insert - Red

If you're working on your 1985-1997 Chevrolet Astro or S-10 with the 4.3L engine and want to firm up the connection between your engine and chassis, these motor mount inserts from Prothane are a solid option. They replace the stock rubber inserts, which can become soft and worn over time, leading to excessive engine movement. By using a stiffer polyurethane material, these inserts help reduce that movement, which can make a noticeable difference in how the engine feels under acceleration and load.

Prothane uses a durable red polyurethane for these inserts. This material is known for its ability to hold its shape and resist tearing, even under the stress of engine torque. Installing these is a straightforward way to improve throttle response and reduce the slop you might feel from worn-out factory mounts. It's a popular upgrade when rebuilding or refreshing the drivetrain on these trucks and vans.
