PPE Transmission Mount; 70 Hardness (11-19 2WD Sierra 2500 HD w/ Allison Automatic Transmission; 20-23 Sierra 2500 HD w/ 6L90 Automatic Transmission)Find parts that fit my vehicle

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 percent 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.

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

_x000D_
• Purple (30A): Ideal for street applications, offering a balance of comfort and performance for everyday driving.
_x000D_
• Green (50A): Perfect for hybrid use, blending off-road capability and street comfort, making it versatile for mixed-use scenarios.
_x000D_
• 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.
