RockNut kit with a 1.25 in. left-hand thread pairs a collet-style locking nut with a weld-in bung to replace traditional jam nuts in suspension linkages. The tapered collet mechanism binds the nut and bung to the joint threads when tightened, reducing the risk of loosening under heavy articulation. It is sized for 1.75 in. x .188 in. wall tube and includes a plated nut and raw weldable bung.
