A unique and wide ratio range to fit almost any popular application. These XD rockers are fully rebuildable and boast precision-sorted needle bearings and hardened roller tips. And they work with most diameter springs and retainers. The new XD design utilizes advanced FEA and CAD design and development to improve strength, stiffness and MOI optimization for drag and circle track applications.
