The Duramax with Allison transmission show what a factory platform can produce and the Duramax Torque-Master line of products are designed and tested to run perfectly to towharder, faster, and heavier. The bolt-on turbos and intercoolers increase boost, lower EGTs and make more power and torque. 

 An incredible factory engine and transmission deserve the best aftermarket parts available. The Torque-Master bolt-on parts for the Duramax allow you to see performance levels you want. Drop-in intercooler and turbo upgrades let you tow harder, faster andmake the torque to move big payloads.

Aerodynamics is what separates the GT-K turbo line from the competition. Equipped with the latest HP CompressorWheels, designed to maximize efficiency at high boost pressures, and the F1 turbine wheel, created to capture the maximum exhaust gas energy and reduce backpressures, the GT-K family of turbos delivers unequaled performance. When paired with the Map Enhancement Porting of the GT-K compressor housings, these wheels flow huge volumes of air at high pressure ratios while still delivering a cool efficient intake charge.
