Our 1-3/8″ Aluminum Split Lock Collar is a two-piece, two-bolt design for balancing the clamping force to ensure proper fitment. 

Lock Collars are used throughout a go-kart or lawnmower racing chassis to secure sprocket hubs, axle hubs, brake hubs, steering components, and more. This locking collar is keyed.

We use this locking collar primarily as a clamp for holding the mufflers to the engine header
