Scorpion Performance

About Scorpion Racing Products

Born on the racetrack and built in the USA, Scorpion Racing Products has spent more than two decades earning its reputation as one of the most trusted names in high-performance valvetrain engineering. Founded in Ocala, Florida by a seasoned race engine builder, the company grew from firsthand motorsports experience into what Summit Racing recognizes as the world's largest manufacturer of roller rocker arms. From championship drag strips to offshore powerboat courses, Scorpion components have been proven under the most punishing conditions imaginable.

American Manufacturing, Race-Proven Quality

What truly sets Scorpion apart is an unwavering commitment to domestic manufacturing and rigorous product validation. Every component is produced right here in the United States using fully automated, robotically controlled tooling that runs around the clock — a level of precision and efficiency that allows Scorpion to deliver world-class quality at competitive prices. Rather than simply selling parts, Scorpion invests heavily in research and development: the company maintains an in-house engine building department, an in-house dynamometer, and actively sponsors race vehicles across drag racing, circle track, monster truck, and offshore boat racing to stress-test every design before it ever reaches a customer.

That real-world validation is why every Scorpion product carries the brand's coveted Lifetime Warranty — a testament to the confidence Scorpion places in its own craftsmanship. Meanwhile, the company continually updates its tooling and manufacturing processes, ensuring that precision standards only improve over time.

The Scorpion Valvetrain Lineup

Scorpion's core expertise lives in the valvetrain. Their Engine Rocker Arms are the flagship product line — fully rollerized designs featuring needle bearing fulcrums and roller tips machined from aerospace-grade 7000 Series aluminum. Whether you need stud-mount rockers for a classic small-block Chevy or shaft-mount Endurance Series arms for an aggressive big-displacement build, Scorpion covers an enormous range of engine families. The brand also offers complete Engine Rocker Arm Kits, which bundle everything needed for a full valvetrain upgrade into a single, application-specific package — eliminating guesswork and ensuring proper component matching right out of the box.

Beyond rocker arms, Scorpion's catalog extends to pushrods, valves, valve springs, stud girdles (valvetrain stabilizer kits), fuel rail kits, lubricants, and more — making it a one-stop resource for serious engine builders tackling street performance, bracket racing, or all-out competition builds.

Why Builders Trust Scorpion

The combination of advanced CNC manufacturing, in-house testing infrastructure, a broad application catalog, and a lifetime warranty makes Scorpion Racing Products a go-to brand for engine builders who refuse to compromise. Whether you are refreshing a weekend cruiser or assembling a race-winning powerplant, Scorpion's dyno-tested, race-proven components deliver the reliability and performance that demanding builds demand.
