Maximize the legendary hauling power of your truck with our complete line of 2006-2007 GM 6.6L LLY/LBZ Duramax towing and accessories. Equipped with the robust 6-speed Allison transmission, the iconic LB7-successor LLY and LBZ Duramax platforms are highly favored for serious towing tasks. Matching that high-torque diesel performance with heavy-duty chassis upgrades is critical to ensure safety, stability, and control when pulling fifth-wheels, equipment trailers, or toy haulers.
At Norcal Diesel Performance, we stock rugged towing equipment engineered to eliminate common hauling weak points. Counteract dangerous rear-end squat and body roll under heavy tongue weights with our premium air helper springs and onboard air compressor kits. We also provide high-capacity trailer receiver hitches, precise electronic brake controllers, and extendable towing mirrors designed to restore clear sightlines around extra-wide loads. From adjustable drop ball mounts to clean, plug-and-play trailer wiring adapters, we supply the utility gear needed for long-distance hauling peace of mind.
Prepare your truck to handle the steepest highway grades and toughest jobsites with complete confidence.
