2001-2010 GM 2500HD/3500HD, 3/4 Ton SUVs Performance Transmission Mount

Las Vegas, NV — Pacific Performance Engineering (PPE), 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.

Replace your OEM Weak Link. Drive With Confidence.

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 are 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

Interchangeable Silicone Bushings:

The PPE Transmission Mount’s dual silicone bushing system is 100% replaceable with three different bushing durometer (hardness) options that accommodate different needs.

• Purple (30 Shore A Hardness): Ideal for street applications, offering 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 drag strip and high-performance applications, this version is for those who demand maximum stiffness and control during high-torque, aggressive driving.

Whether you're hauling heavy loads, crawling over rocks, or hitting dragstrips, the PPE Transmission Mount keeps your driveline securely anchored and provides the confidence that you need.
