DmaxStore has specialized in one thing since 2007: the GM Duramax diesel. Started by a crew that spent years at one of the largest GM dealers in the country, the shop carries and builds parts exclusively for the 6.6L Duramax and 3.0L LM2/LZ0. That single-platform focus means carefully selected, Duramax-specific parts and some of the best pricing you will find on quality components, with none of the overhead that comes from chasing every make and model.
The lineup covers the systems that give Duramax trucks the most trouble: heavy-duty and extended-travel CV axles, XD tie rods and tubular control arms, stainless steel brake lines, billet fuel caps and filter adapters, water pumps, high-flow thermostats, coolant hose kits, upgraded belt tensioners, and Allison transmission coolers. Whether you are chasing reliability on a daily driver or prepping a built truck, these are the parts that keep a Duramax on the road.
