Reactor Products

Reactor Products specializes in SFI-rated billet aluminum automatic transmission flexplates for racing and high-performance applications. The company’s original flexplate has been produced since 1984 and is designed to support reliability, performance, and stability in demanding drivetrains. Each product is precision CNC-machined from solid, aerospace-grade aluminum, SFI tested and approved, and equipped with replaceable starter steel ring gears. Reactor Products says its flexplates are engineered to handle high-horsepower applications and are made in the United States.

The product range includes flexplates for a variety of engine and transmission combinations, including small- and big-block Chevrolet, GM LS, and first-generation LT1 applications. Options include different tooth counts, balance configurations, and heavy-duty designs. Customers can search for a compatible combination or contact the company to discuss custom options and receive personalized help choosing a setup. Reactor Products also provides installation instructions and a flexplate recertification service, and invites businesses to inquire about distribution and private-label opportunities. Its products have been used by national event winners, world champions, and record holders.
