The Energy Suspension motor mount clamshell insert in black is a Hyper-Flex polyurethane component designed as a replacement insert for early GM style mounts. It balances street comfort with the strength to withstand harsher use, resisting oils and contaminants while improving engine location and longevity over OE rubber inserts. Sold individually, it provides a targeted upgrade to worn clamshell-style motor mounts.
