About Proform Parts

Proform Parts (officially Specialty Auto Parts U.S.A., Inc.) has spent over 40 years establishing itself as a leader in the high-performance automotive aftermarket. Founded in Warren, Michigan, the brand has built its reputation by engineering creative solutions for performance enthusiasts who demand innovation without breaking the bank. With a motto of "Innovation & Affordability," Proform has earned the trust of millions of customers through thousands of SKUs, dozens of patents, and a relentless commitment to quality manufacturing.

What sets Proform apart from the competition is a track record of industry firsts. The brand was the first to make widely available affordable, non-remanufactured electric parts and accessories, and pioneered products like the 2-piece timing chain cover, 2-stage in-line fuel filter, and HEI distributor tune-up kits. Today, Proform continues to push boundaries with products like brushless electric fans and wireless vehicle scales — proof that the brand never stops innovating.

Proform is the factory source for both Chevrolet Performance Licensed engine dress parts and Ford Performance Licensed products, meaning you'll find parts bearing the official Bowtie, Ford Racing, Mustang, and Cobra trademarks. Whether you build for the street or the strip, Proform's lineup covers nearly every aspect of engine performance and appearance for GM, Ford, and Mopar platforms.

One of the brand's defining strengths is its cooling lineup. Proform's engine cooling fans — from classic S-blade and straight-blade units to the latest brushless ultra-performance designs — free up horsepower robbed by belt-driven systems while keeping temperatures in check. Complementing the fans, Proform's radiators include the innovative Slim-Fit Radiator System, which integrates the radiator, fan, thermostat, and shroud into a pre-assembled unit under four inches thick — a true rethink of how cooling systems are built.

Under the hood, Proform's alternators are 100% brand new — never remanufactured — and available in a variety of styles including GM 10SI, CS130, and the eye-catching Lightning-Bolt Mini Alternator, which combines compact design with high output for both track and street applications. For those who want their engine bay to look as good as it performs, Proform's engine valve covers are available in chrome, black crinkle, and officially licensed GM and Ford Performance styles that dress up any V8 with factory-authentic flair.

For serious racers and chassis tuners, Proform has also expanded into precision measurement with their vehicle scales, including a cutting-edge 14,000 lb wireless system that brings professional-grade chassis setup capability to the dedicated enthusiast. Each Proform product is backed by warranty and supported by live technicians — reflecting the brand's confidence in everything it builds.
