PPE Engine Mount Kit Pair HD Silicone Bushings for 11-16 GM 6.6L Duramax

Description

The PPE Engine Mount Kit with silicone bushings is a direct-fit upgrade designed for GM 6.6L Duramax trucks. This kit replaces the factory rubber engine mounts with stronger, longer-lasting components that help reduce engine movement, improve throttle response, and minimize vibration under load. CHOOSE YOUR PERFORMANCE LEVEL: The PPE High-Performance Silicone Engine Mounts are available in four application-specific durometers, allowing you to match mount stiffness to your driving style and vehicle use: Blue (40A) – Smooth Street: Maximum vibration damping and ride comfort for daily-driven street trucks. Green (50A) – OEM Firmness: Replicates factory firmness; ideal for occasional towing and light off-road use without sacrificing ride quality. Yellow (60A) – Street/Performance: Balanced option for hybrid use, combining improved drivetrain control with street-friendly comfort. Red (70A) – Race/Competition: Maximum stiffness and engine control for drag strip, sled pull, and high-performance builds. Duramax engines produce significant torque, especially under towing and heavy-load conditions, which can accelerate wear and loosen factory engine mounts. The PPE kit uses reinforced brackets and premium silicone bushings to provide improved support while still allowing controlled movement for optimum performance and NVH (noise, vibration, harshness) balance. This engine mount kit is an excellent upgrade for trucks used in towing, heavy hauling, or frequent start/stop driving, providing a more secure engine mount system that enhances reliability and driver comfort.
