2011–2016 GM 6.6L LML 4x4 ProDuty OEM+ Engine and Transmission Mount Kit

Bring back control and confidence to your 2011–2016 LML Duramax with our ProDuty OEM+ Mounts for Silverado and Sierra 2500/3500HD 4x4 trucks. This complete 3‑mount kit is a premium direct‑fit upgrade for owners who tow heavy, run tuning, or simply want a tighter, more solid feel than the soft factory mounts can deliver. You keep the manners of an OEM truck while gaining the stability and durability your LML needs under real‑world use.

• 2 Engine Mounts
• 1 Transmission Mount

ProDuty OEM+ Mounts for the LML platform use heavy‑duty brackets paired with high‑durometer bushings that are tuned specifically for 2011–2016 GM HD chassis. By significantly reducing engine twist under throttle, the mounts help cut down on drivetrain shake, wheel hop, and the unwanted movement you can feel during launches, gear changes, and steep towing pulls. The bushing compound is carefully balanced so you gain crisp engine control and better feedback without introducing the harsh vibration and noise of race‑style or solid mounts.

This kit installs as a direct replacement for the factory motor mounts, reusing OEM mounting hardware and locations for a clean, OE‑style fit. It works seamlessly on stock‑height trucks and pairs well with leveled and most lifted LML setups, making it a great option whether your truck is a daily‑driven tow rig, work truck, or mild performance build. If you’re ready to get rid of sloppy, sagging factory mounts and upgrade to something built for real use, ProDuty OEM+ Mounts are the logical next step for your 2011–2016 Duramax.
