Low-profile lock-up unit featuring a redesigned billet aluminum lock-up pressure plate engineered to fit beneath the stock primary cover. ⚙️
Surface area has been greatly increased to reduce lever effort and deliver smooth, precise shifting. Three coil spring sets are included to provide a wide range of spring pressures for stock through 200+ hp applications.
The unit ships assembled with a steel inner hub and bearing included, and adjustable pressure arms that increase spring pressure as rpm rise. It is a bolt-on solution requiring no modifications and can be operated wet or dry.
Made in the USA. Derby cover spacer #686-30-16100 is required; the spacer plate is not required when using compatible derby covers #343-30-43015 or #343-30-44015. 🔧
