PPE Performance Transmission Mount 11-19 GM 6.6L Duramax Allison 2WD

Improve drivetrain stability and durability with the PPE Performance Transmission Mount for select Chevrolet Silverado and GMC Sierra HD trucks. Engineered to address the weaknesses of factory transmission mounts, this upgraded design features dual silicone bushings and an increased contact area to reduce shear stress, minimize vibration, and help maintain proper drivetrain alignment under demanding conditions. Factory transmission mounts can deteriorate under heavy loads, high temperatures, and repeated drivetrain movement, potentially contributing to excessive vibration, driveline misalignment, and harsh shifting. The PPE Performance Transmission Mount uses a redesigned structure with dual silicone bushings and a high-strength steel core to provide a more durable connection between the transmission and chassis. The premium silicone bushings are designed to resist heat, weather, and tearing, making this mount suitable for demanding towing, daily driving, off-road use, and high-performance applications. With a 30% larger steel-to-elastomer contact area, the mount distributes loads more effectively to reduce stress concentrations and improve long-term durability. Choose from three interchangeable bushing hardness options to match your driving needs. The 30A purple bushings prioritize street comfort, the 50A green bushings provide a balance of comfort and performance, and the 70A red bushings deliver increased stiffness for high-torque and performance applications. This flexibility lets you customize your transmission mount without replacing the entire assembly.
