Maximize the utility and heavy-duty capabilities of your truck with our complete selection of 2007.5-2010 GM 6.6L LMM Duramax towing and accessories. The LMM Duramax platform brought refined power and a robust Allison transmission to the redesigned Chevrolet Silverado and GMC Sierra HD lines. To pull fifth-wheels, commercial flatbeds, or toy haulers safely, outfitting your GMT900 chassis with upgraded load support and reliable hardware is crucial for maintaining handling stability and stopping power under load.
At Norcal Diesel Performance, we offer a rugged catalog of towing upgrades engineered to eliminate common hauling vulnerabilities. Restore vehicle levelness, eliminate rear-end sag, and improve headlight alignment under heavy tongue weights with our premium air helper springs and onboard air management systems. We also stock heavy-duty trailer receiver hitches, precise electronic brake controllers, and extendable towing mirrors designed to expand your field of vision around wide loads. From high-weight-rated drop ball mounts to clean-fit wiring adapters, we ensure your vehicle is ready for any job.
Equip your LMM workhorse to tow safely across any terrain with total peace of mind. Browse our comprehensive collection of truck accessories online for quick shipping, or stop by our retail storefront in Orangevale, CA for direct product advice and expert installation support!
