 STEERING BLOCKS JP3 steering blocks are designed to compliment the other steering components to provide a complete system. All blocks feature : Ertalyte sheaves that provide a wear resistant surface that is suitable for either wire or vectran Sealed stainless steel deep groove bearings to ensure low friction, smooth quiet running.
