2017–2019 GM 6.6L L5P 4x4 ProDuty OEM+ Engine and Transmission Mount Kit

Lock down the power of your 2017–2019 L5P Duramax with ProDuty OEM+ Mounts for Silverado and Sierra 2500/3500 4x4 trucks. This complete 3‑mount kit is built for owners who tow big, run tuning, or take their L5P off‑road and are tired of the sloppy, loose feel of worn factory mounts. You get a more connected, confident truck that still behaves like a street‑friendly daily driver.

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

For the L5P 4x4 chassis, ProDuty OEM+ Mounts use application‑specific brackets and high‑durometer bushings that dramatically cut down on engine twist under throttle. That added control helps reduce drivetrain shake, wheel hop, and the irritating shudder you can feel when launching hard, shifting under load, or climbing steep grades with a trailer. The bushing compound is carefully chosen to deliver firmer, more precise drivetrain behavior without the harsh vibration and noise that come with solid or race mounts.

Installation is straightforward thanks to a direct‑fit design that reuses your factory hardware and mounting locations for an OE‑style finish. The kit works great on stock‑height 4x4 trucks and integrates well with leveled and most lifted L5P suspensions, making it a smart upgrade for tow rigs, work trucks, and mild performance builds alike. If you want your 2017–2019 Duramax to feel tighter, more controlled, and ready for real use, ProDuty OEM+ Mounts are the upgrade your 4x4 has been missing.
