What T&D Machine Products does
T&D Machine Products is a U.S.-based precision manufacturer founded in 1975 by Larry Tores in his backyard garage, specializing in high-performance shaft mount rocker arm systems for racing and high-performance engine applications. The company designs and builds rocker arm kits for over 400 types of cylinder heads (with one source citing nearly 1,000 configurations), using 2024 aluminum and proprietary chrome-moly steel constructions, and offers a numbered family of performance options (spring oil hole, bushed rockers, steel, shot peening, lightweight, needle bearing tips). Its broader product portfolio includes Johnson Lifters, valvetrain tools (valve spring compressors, lash wrenches, pinion depth checkers, engine blueprinting kits), mounting hardware, and branded apparel, totaling more than 135 SKUs.
The company operates from a single manufacturing facility in Carson City, Nevada, where it runs CNC machining centers and performs all production in-house. Revenue is generated primarily through hardware sales of build-to-order rocker arm systems, lifters, tools, and replacement parts, with ancillary service revenue from rocker arm inspection and rebuild work. Pricing is unit-based and publicly disclosed on the website, with custom configurations quoted on inquiry. Distribution is direct-to-customer via e-commerce (tdmach.com) and phone sales, serving a global base of professional engine builders, professional race teams, and dedicated enthusiast racers across motorsports disciplines including NHRA drag racing, NASCAR, sprint car, and desert off-road racing.
T&D remains privately held under founder Larry Tores, with no disclosed institutional investment, outside ownership, or parent company. The business has grown organically over five decades, relocating from Culver City, California to Carson City in 1992 and expanding facility capacity by 75% in 1999, with ongoing investment in CNC equipment. The company employs more than 50 people, including design and engineering personnel who are themselves active racers, and supports customers worldwide through direct digital channels and an active social media presence on Facebook, Instagram, and YouTube.
