About Jerico Performance Products
Jerico Performance Products is one of the most respected names in American motorsport, with a legacy rooted in racetracks across the country. Founded in 1980 and based in Concord, North Carolina, Jerico has spent more than four decades engineering, manufacturing, and refining high-performance racing transmissions built entirely in the USA. From short-track oval racing to drag strips and road courses, the Jerico name has become synonymous with durability, precision, and winning.
A Legacy Built on the Racetrack
The story of Jerico begins with founder Jerry Hemmingson, whose passion for motorsport drove him to create gearboxes that could outlast and outperform anything else on the market. What started as a specialized racing solution quickly earned a reputation in the NASCAR Cup Series and spread to virtually every form of wheel-to-wheel competition. Today, Jerico transmissions are equally at home on superspeedways, dirt ovals, drag strips, salt flats, and road courses around the world.
A key reason for Jerico's enduring success is its commitment to in-house manufacturing. The company operates a 50,000 square-foot production facility where every stage of design, machining, and assembly is controlled under one roof. This vertically integrated approach allows Jerico to maintain the tight tolerances and consistent quality that racers demand — because in racing, there is no room for compromise.
Engineering Excellence in Every Gear
Jerico offers a comprehensive lineup of manual racing transmissions spanning 2-speed, 3-speed, 4-speed, and 5-speed configurations, each purpose-built for specific racing disciplines. Their transmissions are renowned for several engineering advantages that set them apart from the competition:
- Dog-ring shifting system: Borrowed directly from their NASCAR Cup 4-speed platform, this proven shifting technology enables lightning-fast gear changes with or without the clutch.
- Straight-cut billet gears: All internal gears are CNC-machined from billet steel and heat-treated to Jerico's own specifications — no welded gears are ever used.
- Lightweight aluminum construction: Jerico's 4-speed racing transmissions tip the scales significantly lighter than comparable stock iron units, reducing rotating mass and delivering more usable horsepower to the rear wheels.
- Fully rollerized mainshaft and tailshaft: Precision roller bearings reduce friction and heat buildup, extending service life even under sustained racing loads.
- Built to order: Every Jerico racing transmission is assembled to the buyer's specifications, with unlimited gear ratio options to suit each track and driver preference.
Beyond Complete Transmissions
Jerico's product catalog extends well beyond complete gearboxes. The company supplies a full range of transmission components and rebuild parts — including shift forks, output shaft bushings, snap rings, cases, gears, shafts, thrust washers, and breather fittings — ensuring that Jerico-equipped racers can source everything they need to maintain and rebuild their drivetrain without compromise. This breadth of parts support is a major reason why teams continue to rely on Jerico season after season.
Why Racers Choose Jerico
Across decades of competition, Jerico transmissions have earned a reputation that few brands can match. Racers running Jerico gearboxes consistently report completing full seasons without a single transmission failure — a testament to the engineering integrity and build quality that goes into every unit. Whether you are setting up a sprint car for a dirt oval, building a late-model stocker for asphalt, or preparing a purpose-built drag car, Jerico Performance Products offers a transmission solution that has been proven under the most demanding conditions motorsport can throw at it.
