2011-2019 Duramax LML/L5P PPE Transmission Mount Rear - 30 Hardness (169044130)
For 2011-2019 four-wheel-drive Allison trucks, PPE offers a rear transmission mount that addresses the same failure points as the front unit: soft factory rubber that degrades under sustained load and high-torque shifts. The Purple 30A rear mount is the softest option in the lineup, suited for daily drivers and street trucks where ride quality matters. Dual-silicone bushings with a 30 percent larger contact area keep the transmission planted without transmitting excessive harshness into the cab. The Green 50A rear mount is the versatile mid-range option, balancing street comfort with performance driving and moderate towing. Dual-silicone bushings with a 30 percent larger contact area keep the transmission firmly located without the harshness of a full-race bushing. The Red 70A rear mount is the firmest option, built for sled pull, drag strip, and high-output builds where maximum driveline rigidity is the goal. Dual-silicone bushings with a 30 percent larger contact area handle the torque without the failure modes of the stock rubber insert.
- Purple 30A durometer: street comfort, ideal for daily use
- Green 50A durometer: balanced street and performance use
- Red 70A durometer: maximum stiffness for drag and competition use
- Dual-silicone-bushing design reduces shear load
- 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
