Our broad selection of ring-and-pinion ratios, transmissions, and lightened gears is available for just about every vehicle made from the 1940s through and including new vehicles. DIY customers and professional installers alike will appreciate our installation kits, which come complete with everything needed to install a ring-and-pinion set; right down to the seals, gaskets, and RTV. Consistent gears are VERY important to installers. Once a mechanic successfully installs their first Richmond gearset, they will know how to setup all future Richmond gears. Richmond performance products are the result of continuous research and development combined with the state-of-the-art manufacturing in our facilities worldwide. All Richmond performance products meet strict quality standards through advanced manufacturing techniques and are backed by a strong warranty. Our in-house quality control lab utilizes state-of-the-art equipment to continuously check Richmond products for strength, tolerance, and hardness. Only after meeting stringent quality standards are Richmond products stamped with the Double Diamond seal of approval.
