Radius Pushrods have the same features as other Hi-Tech Pushrods, with the addition of a 210? radius rather than standard 180? radius. Featuring a one-piece design from .080? wall, seamless chromemoly tubing that ensures exceptional durability, the pushrods are heat-treated for maximum strength, OD ground for consistency and black-oxide finished with length and part number laser etched on for easy identification.
