Stop Letting Engine Flex Kill Your Power

If you’re pushing serious horsepower through your 2011–2016 Duramax, the last thing you need is a weak factory engine mount letting your drivetrain twist under pressure. The Wehrli 100160 Heavy Duty Engine Mounts are built to put an end to broken mounts and unwanted engine movement. Whether you’re towing heavy, running compound turbos, or launching hard at the track, these mounts keep your engine firmly in place so all that torque stays where it belongs. You’ll notice a more connected feel behind the wheel, with reduced slop and tighter power transfer throughout the drivetrain. Each mount is equipped with durable polyurethane bushings that outlast rubber and hold up under extreme heat and stress. The mounts come finished in a clean, corrosion-resistant powder coat and include all the high-grade hardware and thread-locker you need for installation. These mounts do increase engine noise and vibration, but that’s a small tradeoff when you’re building for real performance.

Built For High Horsepower And Hard Abuse

Wehrli’s Heavy Duty Engine Mounts are purpose-built for high-output 6.6L Duramax LML applications from 2011–2016, giving you a rugged solution to engine deflection under heavy load. Designed to preserve the alignment geometry of the factory mounts, they feature polyurethane bushings that add strength without sacrificing fitment. Poly bushings offer a major upgrade over soft rubber, delivering long-term durability while resisting collapse under heat and torque. Each set includes both left and right mounts, along with premium fasteners and thread-locker to ensure everything stays secure once installed. The mounts are precision fabricated and powder coated for maximum corrosion resistance, making them ideal for trucks that see both street and off-road duty. While these are not recommended for daily drivers due to increased engine vibration and noise, they’re exactly what you want if your setup demands better control and reliability. For Duramax owners chasing higher performance goals, this upgrade is a proven foundation for keeping your engine locked in place.
