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 in a redesigned housing that spreads the load across 30 percent more contact area. The Green 50A hardness is the mid-range option: firm enough for spirited driving and mixed towing use, but not so stiff it becomes uncomfortable on the street.

Features

• Green 50A durometer: balanced street and performance 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
• 1 Year Limited Warranty

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.
