PPE 2011-2019 GM 2500/3500HD Allison 2WD, 2020-2023 6L90 4WD Transmission Mount

6L90 4wd Transmission Mount, GM 2500HD/3500HD Allison 2wd

The PPE Performance Transmission Mount is a critical upgrade for any GMC/Chevrolet HD truck owner seeking superior durability, performance, and reliability. Factory transmission mounts, notorious for their weak rubber compounds and high-shear-load design, can degrade quickly under stress. These stock mounts often lead to excessive vibration, driveline misalignment, and hard shifting - especially under sustained heavy loads or during aggressive driving.

The PPE Transmission Mount is engineered to tackle all the weaknesses of factory mounts through a complete redesign. Featuring dual-silicone bushings, it reduces shear load significantly and distributes pressure more efficiently. The 30% larger steel-to-elastomer contact area ensures that the load on each square inch of rubber is reduced, further minimizing the risk of failure under high stress.

The premium-grade silicone compound used in the mount is heat-resistant, weatherproof, and tear-resistant, providing long-lasting durability. It thrives in environments with high vibrations, heavy loads, extreme temperatures, reliably anchoring your transmission to the chassis.

Choose Your Performance Level

The PPE Performance Transmission Mount comes in three application-specific durometer hardnesses, each designed for different driving styles and conditions:

• Purple (30A): Ideal for street applications, offering a balance of comfort and performance for everyday driving.
• Green (50A): Perfect for hybrid use, blending off-road capability and street comfort, making it versatile for mixed-use scenarios.
• Red (70A): Designed for drag strip and high-performance applications, this version is for those who demand maximum stiffness and control during high-torque, aggressive driving.

The silicone bushings are also replaceable/interchangeable, allowing you to easily swap them for different driving applications.

No matter how you use your truck - whether for towing, off-roading, or racing - the PPE Performance Transmission Mount is a no-brainer upgrade.
