T&D Machine Products, based in Carson City, NV, is a renowned brand in the performance industry. The company was founded in 1975 by Larry Tores, a skilled draftsman turned race car enthusiast. T&D Machine Products initially manufactured race car parts in Tores' backyard garage before expanding into private-labeled parts for other manufacturers.

As Tores accumulated wins on the track and set numerous records, he developed a unique shaft rocker arm system that became the spark for T&D's success. In the early 1980s, GM's Buick Division recognized the significance of T&D's shaft rocker system and incorporated it into their V-6 engine program, ultimately impacting NHRA drag racing, the Indy 500, and NASCAR competitions. This technology quickly spread to other engines, cementing T&D's focus on manufacturing shaft rocker arm systems for various motorsports disciplines.

Since then, T&D has relocated to Carson City, NV, and experienced continuous growth. The company has expanded its facilities and invested in state-of-the-art CNC machining centers to ensure the highest quality products. Today, T&D manufactures rocker arm systems for a vast range of cylinder heads, earning a reputation for exceptional performance, reliability, and longevity.

With a team of over 50 highly qualified employees, T&D Machine Products remains at the forefront of innovation and continues to provide top-notch products for racers, Sprint Car engine builders, off-roaders, and many more
