2001–2019 GM HD Trucks and 3/4 SUVs Transmission Mount

Las Vegas, NV — Pacific Performance Engineering proudly unveils its Transmission Mount for 2001-2019 GM HD Trucks equipped with the Allison Transmission. Designed to meet the extreme demands of towing, off-roading, and high-performance driving, this innovative upgrade is a major leap forward in performance and reliability.

OEM transmission mounts are not built for longevity. Their high-shear design and soft rubber compound make them prone to failure - especially under heavy-duty use, which accelerates wear and breakdown. Moreover, the OEM mount relies entirely on a single piece of rubber to connect the upper and lower brackets—with zero hard connection. The poorly formulated rubber compound in OEM mounts is also susceptible to heat and weather, resulting in rubber degradation, cracking, and separation, which can cause excessive vibration, driveline misalignment, and clunky shifting. The PPE Transmission Mount addresses these issues with a complete redesign that offers true structural integrity and long-term durability.

Key Features & Benefits:

• Dual silicone bushings securely encapsulated inside the upper steel bracket.
• A high-strength steel core that passes through the bushings, providing a solid link.
• 30% Larger Steel-Elastomer Contact Surface Area: minimizes stress concentration and reduces shear load.
• Premium Heat-Resistant Silicone Compound: Built to handle extreme temperatures and mechanical abuse far beyond what OEM mounts can endure.
• Replaceable & Interchangeable Bushings: Easily fine-tune your setup by swapping bushings for different driving styles without replacing the entire mount

Choose the right bushings for your driving needs:

Purple (30 Shore A Hardness): Ideal for street applications, this softer option offers a balance of comfort and performance for everyday driving

Green (50 Shore A Hardness): Perfect for hybrid use, blending off-road capability and street performance, making it versatile for mixed-use scenarios

Red (70 Shore A Hardness): Designed for strip and high-performance applications, this version is for those who demand maximum stiffness and control during high-torque, aggressive driving

Whether you're towing, off-roading, or driving aggressively, the PPE Performance Transmission Mount offers the strength and customization you need to keep your drivetrain stable and responsive.
