GMC P35 Parts & Accessories

The GMC P35 one-ton step van is a forward control commercial platform built to handle heavier payload requirements than the P25, using a reinforced frame and upgraded axle components to support gross vehicle weights in the one-ton range. These vans were powered by small-block V8 engines and the 250 inline-six across various model years, all using carburetor-based fuel delivery and four-wheel drum brakes. Fleet operators and restorers working on P35 vans need accurately sourced replacement parts to maintain safe brake performance, reliable fuel delivery, and correct engine sealing. This collection addresses those core maintenance needs for the P35 platform.

Popular Upgrades

High-demand parts for the GMC P35 include Monroe or Gabriel heavy-duty front shock absorbers sized for one-ton chassis, Delphi or Carter fuel pumps for the mechanical fuel delivery system, Gates belts and hoses for engine cooling and accessory drive maintenance, Raybestos or Wagner brake shoes and wheel cylinders for all four drum corners, and Fel-Pro gasket sets for the 305 and 350 small-block V8 engine rebuilds. Moog heavy-duty tie rod ends and ball joints address the increased steering loads of the one-ton front axle setup.

Performance and Handling

The P35 forward control chassis uses front coil springs and rear leaf springs rated for the one-ton payload range, designed to remain flat and stable under full commercial loads. Replacing worn Moog or TRW steering components restores directional accuracy that degrades with high delivery mileage. Engine reliability depends on consistent fuel delivery, making Carter or Delphi pump replacements and Wix or Purolator filter service essential maintenance items for the P35 fleet.

What brake parts fit the GMC P35 step van

The P35 uses drum brakes sized for the one-ton gross vehicle weight rating, with larger wheel cylinder bores and wider shoe dimensions than the P25 setup. Raybestos and Wagner catalog complete brake kits specific to the P35 axle, including shoes, wheel cylinders, return springs, and adjuster hardware. Confirming the year and rear axle code before ordering ensures the correct shoe arc and cylinder sizing for a complete service.

Which belts and hoses are correct for the GMC P35

Gates manufactures V-belts and serpentine belt kits for each P35 engine application, along with molded coolant hoses sized to fit the 250 inline-six and 305 or 350 V8 engines. Each hose is formed to match the exact routing of the original equipment, avoiding fitment issues that can occur with universal hose sections. Replacing the belt and hose set as a maintenance package reduces the risk of roadside breakdowns caused by aging rubber components.
