Pioneer Automotive 603457 Engine Mount

The Pioneer Automotive 603457 is a direct-fit replacement engine mount designed to secure the engine to the chassis while dampening vibration for a smooth, quiet ride. Pioneer's Sure-Fit System puts each mount through application-specific testing on vehicle fixtures before it ships, so installation is straightforward with no modifications required. The housing is crafted from high-grade metal with a corrosion-resistant coating — or cast from pure aluminum depending on the application — then bonded with a blended rubber compound tuned specifically to the vehicle's characteristics. Where the application calls for it, the design incorporates seamless hydraulic fill or electronic control to deliver precise vibration absorption.
