GMC PB1000 Series Parts & Accessories

The GMC PB1000 Series step van is a forward control half-ton platform sharing its engineering foundation with the P-series van lineup, designed for commercial delivery and route service applications. These vans used inline-six and small-block V8 engines with carburetor-based fuel delivery and four-wheel drum brakes across their production years, making them mechanically straightforward to maintain. Fleet operators and restoration builders working on PB1000 vans need correctly specified replacement parts to keep brake systems safe, fuel delivery reliable, and engine seals intact. This collection provides brake hardware, fuel system components, engine gaskets, and suspension parts for the PB1000 platform.

Popular Upgrades

Commonly sourced parts for the GMC PB1000 include Monroe or Gabriel shock absorbers for the front suspension, Carter or Delphi mechanical fuel pumps for the carburetor system, Gates belts and coolant hoses for accessory drive and cooling maintenance, Raybestos or Wagner brake shoes and wheel cylinders for drum service at all four corners, and Fel-Pro head gaskets and engine gasket sets for inline-six and small-block V8 rebuilds. Moog tie rod ends and ball joints are the preferred choice for restoring front-end steering accuracy on worn PB1000 chassis.

Performance and Handling

The PB1000 uses a forward control chassis with front coil springs and rear leaf springs rated for the half-ton commercial payload range. Replacing worn steering linkage components with Moog or TRW hardware and installing correctly rated Monroe or Gabriel shocks restores the stable, flat handling required for urban delivery routes. Engine output stays consistent with fresh Wix or Purolator filters and properly functioning fuel delivery components for the carbureted setup.

What brake parts fit the GMC PB1000 Series step van

The PB1000 uses drum brakes at all four corners, with shoe widths and wheel cylinder bore dimensions matched to the half-ton axle weight rating. Raybestos and Wagner catalog complete drum brake service kits covering shoes, wheel cylinders, return springs, and adjuster hardware for the PB1000. Ordering by year and axle specification ensures the correct shoe arc and cylinder bore for a complete service rebuild.

Which engine gaskets are correct for the GMC PB1000

Fel-Pro offers application-specific head gaskets and complete engine gasket sets for the 250 inline-six and 305 or 350 V8 engines installed in PB1000 vans. Multi-layer steel head gaskets provide a more reliable combustion chamber seal than original composition materials on engines with worn or resurfaced cylinder heads. Confirming the engine displacement and cylinder head casting number before ordering ensures the correct bore dimension and torque specification.
