GMC P1500 Parts & Accessories

The GMC P1500 half-ton step van is a forward control platform built for commercial delivery and route service applications, featuring a body-over-frame design that maximizes cargo capacity with a short overall footprint. These vans used inline-six and small-block V8 engines through several generations, with mechanical fuel delivery and drum brake systems that benefit from quality replacement parts. Owners maintaining working fleets or restoring classic step vans need parts that meet or exceed original specifications. This collection covers everything from engine sealing and fuel delivery to suspension refresh and brake restoration for the P1500 platform.

Popular Upgrades

The most frequently replaced components on the GMC P1500 include Gabriel or Monroe shock absorbers for the front suspension, ACDelco fuel pumps and filters for the carbureted fuel system, Gates belts and hoses for engine accessory and cooling circuits, Raybestos or Wagner brake shoes and wheel cylinders for all four corners, and Fel-Pro head gaskets and valve cover gaskets for the small-block engine family. Owners also source Moog tie rod ends and ball joints to restore steering precision on high-mileage chassis.

Performance and Handling

The P1500 uses a forward control chassis with coil springs in front and leaf springs at the rear, sized for the half-ton gross vehicle weight rating. Keeping this suspension refreshed with quality Moog or TRW steering components and correctly rated spring hardware restores the flat ride required for city delivery routes. Engine performance on these vans is closely tied to fuel system condition, so Delphi or Carter fuel pump replacements combined with Wix or Purolator filtration maintain consistent power output across the operating range.

What brake parts fit the GMC P1500 step van

The P1500 uses drum brakes at all four corners across its production years, with wheel cylinder sizing and shoe arc dimensions varying by axle weight rating. Raybestos and Wagner both offer complete drum brake kits matched to the P1500 axle specifications. Confirming year and axle ratio before ordering ensures the correct shoe width, cylinder bore, and hardware kit are included for a complete service rebuild.

Which engine gaskets are correct for the GMC P1500

P1500 vans equipped with the 250 inline-six or 305 and 350 small-block V8 engines each require specific gasket sets. Fel-Pro offers application-specific head gaskets and complete engine gasket sets for each displacement, with multi-layer steel construction on the head gaskets providing a more durable seal than original composition designs. Matching the gasket set to the exact engine displacement and cylinder head casting number avoids leaks at the mating surfaces.
