GMC 150 Parts & Accessories

The GMC 150 has a dedicated following among restoration enthusiasts, performance builders, and daily drivers who value the combination of domestic truck reliability and broad aftermarket support that this platform offers. From basic replacement hardware keeping a workhorse truck on the road to performance parts unlocking the potential of the original V8 engines, the aftermarket ecosystem for this model continues to grow. This platform benefits from a robust aftermarket parts network that covers everything from routine maintenance hardware to performance upgrades that meaningfully improve power, handling, and appearance. Proper fitment is especially important on this platform because year and trim variations can affect which parts are compatible.

Popular Upgrades

Popular upgrades for the GMC 150 include Edelbrock Performer intake manifolds and 600 CFM carburetors for small and big block V8 applications, Flowmaster and Borla exhaust systems for the stock exhaust manifold to cat-back circuit, and Bilstein B6 shock absorbers for improved handling on the original front and rear suspension geometry. Brake upgrades including front disc conversion kits and slotted rotors from PowerStop are consistently popular for older trucks. Exterior upgrades including weatherstrip, door handles, and trim components from Dorman and Standard Motor Products help owners restore worn cosmetic components. Lighting upgrades including Morimoto LED headlight and taillight assemblies are a popular modernization for this platform.

Performance and Handling

The GMC 150 platform shares components with other GM trucks of its generation, providing broad cross-compatibility that makes parts sourcing straightforward from the large network of suppliers cataloging this platform. Suspension restoration using polyurethane bushings from Energy Suspension or Moog restores original ride quality and handling precision lost to aging rubber components. Replacing worn control arm bushings and ball joints as a complete axle refresh is the most cost-effective approach for high-mileage vehicles. Proper alignment after any suspension replacement confirms the suspension geometry is restored to factory specification.

What engine performance upgrades work best on the GMC 150?

Edelbrock Performer intake manifolds paired with a Holley 600 or 750 CFM carburetor and matching aluminum heads are the foundation of a reliable performance street build for the small block V8 found in most GMC 150 configurations. Adding a mild performance camshaft from Comp Cams with matching valve springs in the 218 to 224 duration range provides a strong combination of low-end torque and upper RPM breathing. A quality Flowmaster or Borla exhaust from the manifolds back completes the basic performance package.

Are there disc brake conversion kits available for older GMC 150 trucks?

Yes, disc brake conversion kits from Wilwood, Baer, and Russell are available for most GM truck platforms of this era, allowing a complete front disc upgrade that dramatically improves stopping performance. Rear disc conversion kits are also available for platforms that came with four-wheel drum systems. All disc conversion kits include the spindles, calipers, rotors, and hardware needed for a complete swap without custom fabrication.
