Say goodbye to sloppy shifts and worn out mounts with the PPE Allison 1000 Performance Transmission Mount for 2001–2010 GM 2500HD/3500HD trucks.
If you're pushing your Duramax hard, whether towing, off-roading or racing this is the upgrade your transmission's been waiting for. Stock rubber mounts are known to break down under pressure, causing vibrations, driveline misalignment, and rough shifting. PPE fixes all that with a completely re-engineered mount featuring dual silicone bushings and a 30% larger steel-to-elastomer contact area, cutting down on stress and delivering rock-solid performance under load. The high grade silicone compound used is heat-resistant, tear proof, and built to thrive in high vibration, high temperature conditions.
You can choose your performance level:
-
Purple 30A: Great for daily driving, smooth and balanced.
-
Green 50A: Best of both worlds, perfect for street and off-road use.
-
Red 70A: Built for serious performance, firm and responsive under big torque.
The silicone bushings are interchangeable, so you can swap stiffness levels anytime your setup or driving style changes. No matter how you use your truck, the PPE Performance Transmission Mount delivers unmatched durability and control, making it a must-have for any serious HD build.
