How it works
After checkout, we route your vehicle info and part SKU to verified installation shops near you. Local installers review the job and submit competitive bids; you pick the shop you want based on price, reviews, and availability. Your name and email stay private until you select an installer.
Pricing
You pay for the bid from your preferred shop. The full amount is shown before you confirm — installers cannot add charges without your written consent. Payments are processed securely by Stripe.
Your privacy
During bidding, shops see only your service ZIP code, vehicle year/make/model, and the part SKU — not your name, email, or address. Only the shop you select receives your contact details after payment. We never sell your personal information.

About DMAXStore
DmaxStore is dedicated to one thing: helping GMC and Chevy Duramax diesel owners get the most out of their trucks. Since 2007, DmaxStore has built its reputation around Duramax-specific parts, performance upgrades, replacement components, and technical knowledge for diesel truck enthusiasts.
Rather than trying to cover every make and model, DmaxStore focuses specifically on the Duramax platform. That specialization allows the company to carefully select products for their quality, performance, fitment, and value while providing customers with knowledgeable support when choosing parts for their trucks.
Duramax Parts From People Who Know Duramax Trucks
DmaxStore was founded after its owner spent seven years working for one of the largest GM dealers in the United States, where he earned the GM Mark of Excellence award. That experience helped establish the foundation for a business centered entirely around the GMC and Chevy Duramax diesel community.
Today, DmaxStore offers parts and upgrades covering a wide range of Duramax applications, from the original LB7 through the latest generations of the L5P, along with Duramax-powered Colorado and Canyon applications. Their product selection includes everything from maintenance and replacement parts to fuel-system upgrades, suspension components, drivetrain parts, steering upgrades, engine performance products, and more.
Performance, Replacement & Upgrade Parts
Whether you're maintaining a high-mileage Duramax, restoring an older Silverado or Sierra, or building a truck for increased performance, DmaxStore offers products designed around the needs of diesel truck owners.
