Prothane 1-504 Motor Mount Insert Kit Pair Urethane Engine Mount Insert

The Prothane 1-504 is a motor mount insert kit, also called an engine mount insert, sold as a pair. Prothane first used specially formulated urethane inserts to solve problems on FWD performance cars, and this part continues that approach.

Key Features:

• Urethane insert design that limits engine movement
• Improves hard-start traction and shifting performance
• Limits motor travel
• Reduces the chance of breakage
• Application-specific engineering

Limiting engine movement helps put the power to the wheels. It also firms up the engine's connection to the chassis during hard launches and shifts.
