1-3/8" Aluminum Split Lock Collar – Keyed, 2-Piece Design for Precision Clamping


Our 1-3/8" Aluminum Split Lock Collar features a two-piece, two-bolt design that ensures even clamping pressure and a secure fit without distorting your axle or tubing. Made from lightweight, durable aluminum, this collar includes a machined keyway for 1/4 axle keyways—ideal for high-performance applications.


Lock collars are used across go-kart and racing lawnmower chassis setups to secure components such as:

  • Sprocket hubs
  • Brake hubs
  • Axle hubs
  • Steering rods
  • Custom fabrication assemblies


This particular model is also commonly used as a clamp to secure RLV mufflers to engine headers, providing a stable and vibration-resistant hold during race conditions.
