Chevy & GMC Duramax Diesel Parts

The Duramax has been GM's heavy-duty diesel since 2001, and each generation has its own needs. This collection shows every part we carry for Chevy Silverado and GMC Sierra 2500HD and 3500HD trucks with the 6.6L Duramax, LB7 and LLY through LBZ, LMM, LML and today's L5P.

Inside you'll find FASS lift pumps to protect the CP3 or CP4 injection pump, Fleece Performance fuel and turbo parts, S&B cold air intakes, Titan Turbos, Banks Power and BD Diesel upgrades. For the chassis and body there are Air Lift and Firestone air springs, Bodyguard bumpers, tonneau covers and Husky floor liners.

To narrow it down, open the Shop by Truck menu and pick your years: 2001-2005, 2006-2010, 2011-2016, 2017-2019 or 2020 and newer. Fitment notes on every product page list the exact cab, bed and model years.

We're based in Ropesville, just southwest of Lubbock, so West Texas truck owners can call (806) 503-2161 or stop by the shop. Give us a call before you order if you want a second opinion on what fits your Duramax.
