Motor mounts are critical components that secure the engine to the chassis while isolating vibration. Over time, the rubber compound deteriorates from exposure to heat, oil, and stress, leading to excessive engine movement and vibration. Replacing worn motor mounts restores smooth operation and prevents damage to other drivetrain components.

This mount is designed for the front mounting position on a wide range of Polaris snowmobile models from 1992-1999, including XLT, XCR, Ultra, Storm, and Trail series sleds equipped with 440cc, 500cc, 600cc, and 700cc engines.
