Valve springs designed for drag racing represent the cutting edge of dual and triple spring technology. Metallurgists and engineers are pushing the boundaries of materials and technology to ensure PAC Racing Springs retainers, cups, locks, springs and other valve train associated products are the cream of the drag racing crop. The use of extremely clean (free of scabs and inclusions) steels and state of the art CNC spring coiling equipment give Peterson spring makers the best tools and materials available for crafting high-performance drag racing valve springs. PAC Racing Springs products are found in many professional as well as hobbyist level competition circles.
