Description
Upgrade the bottom end of your Duramax with the DmaxStore Performance Main Stud Kit, designed to provide stronger, more consistent clamping of the main caps than the factory torque-to-yield main bolts. Replacing the factory hardware is especially worthwhile during an engine rebuild or performance build, helping keep the main caps securely in place and reducing the potential for unwanted movement under increased cylinder pressure and engine load. Made from 8740 chromoly steel with a black oxide finish for corrosion protection, the kit includes everything needed to replace the factory main hardware: 10 performance main studs, 10 flat main stud washers, 10 high-strength 12-point nuts, 10 main side bolts, 10 main side bolt washers, high-torque fastener assembly lubricant, and installation instructions. This kit will not work with aftermarket main girdle kits, so verify your engine configuration before installation.

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.
