Factory Allison transmission mounts wear out faster than they should, and when they go, you get vibration, driveline misalignment, and rough shifting. PPE's Performance Transmission Mount replaces the stock rubber with dual-silicone bushings that spread the load across 30 percent more contact area, resisting failure under heavy towing and hard use. The Red 70A hardness is purpose-built for high-performance and drag strip applications where maximum stiffness and control matter more than NVH.

Features

• Red 70A durometer: maximum stiffness for drag and competition use
• Dual-silicone-bushing design reduces shear load and improves durability
• 30 percent increased steel-to-elastomer contact area
• Reduced vibration and driveline misalignment
• Interchangeable silicone bushings, available in 30A, 50A, and 70A

Manufacturer Description

The PPE Performance Transmission Mount is engineered to replace the factory mount's weak rubber compound and high-shear-load design. Featuring dual-silicone bushings with 30 percent more steel-to-elastomer contact area, it distributes load more efficiently and resists failure under sustained towing, heavy loads, or aggressive driving. The premium silicone compound is heat-resistant, weatherproof, and tear-resistant, and the bushings are interchangeable to swap between hardness ratings as your driving application changes.
