Upgrade fuel range on 2004-2010 Chevy Silverado and GMC Sierra 2500/3500 6.6L Duramax LLY, LBZ, and LMM crew cab short bed trucks with S&B's 62-gallon midship replacement tank. It replaces the smaller factory tank, includes an S&B sending unit, supports gooseneck and 5th wheel setups, and is transfer-pump ready with a 1/2-inch NPT fitting. The tank's larger footprint adds reserve capacity at low-fuel levels and helps extend range for towing, fleet, and work-truck use. Notes: the OE skid plate is not compatible, DTE cannot be reprogrammed on GM trucks, and high-flow truck-stop nozzles may not shut off automatically.
