2020-2025 GM 6.6L Duramax 4x4 ProDuty OEM+ Engine and Transmission Mount Kit

The latest‑generation 2020–2025 GM HD trucks were built to tow heavier and work harder than ever, and ProDuty OEM+ Mounts make sure your 6.6L Duramax can keep up. This complete 3‑mount kit is a premium direct‑fit upgrade for Silverado and Sierra 2500/3500 4x4 models, aimed at owners who run big trailers, daily work loads, or tuning and want a tighter, more controlled feel than the soft factory mounts can offer. You get OEM‑style refinement with the added stability and durability your newer‑body truck needs in the real world.

• 2 Engine Mounts
• 1 Transmission Mount (4x4)

ProDuty OEM+ Mounts for the 2020–2025 L5P 4x4 platform use robust brackets and high‑durometer bushings tuned specifically around the updated GM HD chassis and its higher torque output. By significantly reducing engine movement under throttle, these mounts help cut down on drivetrain shake, wheel hop, and the subtle shudder you may feel when launching, shifting under load, or towing at the truck’s elevated capacities. The bushing compound is chosen to keep NVH in check, so your truck still feels like a modern, comfortable HD while delivering a more precise, connected response when you’re working it hard.

This kit installs as a direct replacement for the OEM motor mounts, reusing factory mounting hardware and locations for a clean, OE‑style fit. It integrates seamlessly with stock‑height 4x4 trucks and works well with the leveled and lifted setups that are common on late‑model tow rigs and off‑road builds. If you depend on your 2020–2025 Duramax for serious towing, hauling, or tuned performance and want to get rid of sloppy factory mount behavior without sacrificing comfort, ProDuty OEM+ Mounts are the logical upgrade for your newest‑generation GM HD.
