Upgrade the utility and hauling stability of your truck with our complete selection of 2004.5-2005 GM 6.6L LLY Duramax towing and accessories. The LLY Duramax platform brought variable-geometry turbocharging to the Chevrolet Silverado and GMC Sierra HD platforms, creating a highly responsive engine configuration built for pulling heavy loads. Maximizing this high-torque potential requires robust load support and reliable hardware to pull large trailers, heavy equipment, or toy haulers safely and comfortably.
At Norcal Diesel Performance, we offer a rugged catalog of heavy-duty towing equipment built to match your truck's high-output platform. Level out your ride height and eliminate dangerous rear-end sag with high-capacity air helper springs and onboard air management kits. We also supply custom-fit trailer receiver hitches, advanced electronic brake controllers, and extendable towing mirrors designed to provide an uncompromised view around wide trailers. From adjustable drop hitches and heavy-duty tie-downs to clean-fit wiring adapters, we ensure your vehicle is ready for any job.
Equip your LLY workhorse to conquer steep highway grades and rugged worksites with total confidence. Browse our durable collection of truck accessories online for quick shipping, or pull into our retail storefront in Orangevale, CA for expert product guidance and professional installation support!
