GMC K35/K3500 Pickup Parts & Accessories

The GMC K35/K3500 Pickup is a 1-ton 4x4 workhorse built on the C/K platform and engineered for maximum payload, towing, and durability well beyond what the 3/4-ton K2500 can handle. The K35 designation was used through the late 1980s before transitioning to K3500 in 1988, but both refer to the same class of truck with its Dana 60 front axle, dual rear wheels on many configurations, and heavy-duty suspension tuned for consistent performance under full load. Engine choices ranged from the 5.7L 350 and 7.4L 454 big blocks to the 6.5L turbodiesel, each requiring application-specific exhaust, intake, and maintenance components. These trucks remain highly sought after for construction, towing, and conversion projects requiring a robust platform.

Popular Upgrades

Banks Power is the leading brand for 6.5L turbodiesel upgrades on the K35/K3500, offering exhaust manifolds, intercooler systems, and turbo upgrades that measurably improve towing power and engine longevity. Bilstein 5100 shocks provide upgraded front and rear damping for both single-rear-wheel and dually configurations. Moog front end components including ball joints, tie rod ends, and steering components address the wear accelerated by heavy front axle loads. MagnaFlow and Flowmaster offer exhaust systems for the 5.7L and 7.4L gas engines that add sound and improve exhaust scavenging.

Performance and Handling

The K35/K3500's Dana 60 front axle and heavy-duty leaf spring rear suspension are built for load, but they benefit from upgraded Rancho or Bilstein shocks when carrying payloads near the maximum rating. A 2-inch level kit or a modest lift with factory-compatible spacers keeps tire clearance adequate for 35-inch all-terrain tires on single-wheel configurations. Transmission upgrades including Transgo shift kits for the 4L80-E or NV4500 clutch replacements improve driveline confidence when the truck is regularly used at or near its gross combination weight rating.

What is the difference between K35 and K3500 GMC trucks?

The K35 and K3500 are the same class of 1-ton 4x4 truck at different points in GMC's naming history, with K35 being the older designation used through approximately 1987 and K3500 replacing it in 1988 when GMC modernized their model nomenclature. Parts compatibility between late K35 and early K3500 trucks is strong for chassis and drivetrain components, though body panels, interior trim, and some electrical items differ by body style generation. When ordering parts, always confirm the specific model year and configuration rather than relying solely on the K35 or K3500 designation.

Do K3500 dually trucks require different brake parts than single rear wheel versions?

Yes, K3500 dually trucks use a different rear brake drum diameter and hub configuration than single-rear-wheel K3500 pickups, and parts must be ordered by dually or SRW designation to ensure correct fitment. StopTech and Raybestos both catalog rear brake hardware separately for dually and SRW applications within the K3500 lineup. Front brake components are typically shared between dually and SRW versions since both use the same Dana 60 front axle and corresponding caliper and rotor setup.

Why These Parts Fit Right

Every part in this collection is application-matched to the GMC K35/K3500 Pickup's specific platform, including dually versus SRW distinction where relevant, to prevent the fitment errors that waste time and money. Fast shipping gets your parts to you quickly, and expert support is available to verify compatibility on complex configurations like dually conversions or diesel-powered examples. All orders are processed with precision so your parts arrive ready for installation.
