More About Duramax

GM introduced the 6.6L Duramax diesel as an available engine option for their Silverado and Sierra HD pickups in 2001. The now 20+ year old LB7 was the first common rail diesel in the domestic light duty truck market for the US and also powered the Chevrolet Silverado truck now known as 'After Hours' which helped found our business and passion for diesel performance. Today we support all Duramax engine platforms and continue to lead the way in performance and appearance part upgrades for these trucks. Whether you're restoring a Chevy or GMC NBS 2500 / 3500 HD diesel, building a competition pulling vehicle or drag truck, or simply looking to get the most performance out of your daily driver / work truck L5P, our team of Duramax experts can help!
