Description

1-1/4" Aluminum Split Lock Collar – Keyed, 2-Piece for Racing Go-Kart Axles


Our 1-1/4" Aluminum Split Lock Collar features a precision two-piece, two-bolt clamping design that evenly distributes force around the axle, ensuring a secure fit without distortion. Crafted from lightweight, CNC-machined aluminum and featuring a 1/4" keyway, this collar is purpose-built for racing environments where stability, alignment, and reliability are essential.


This is the go-to collar size for Oval (LTO – Left Turn Only) go-kart chassis, fitting the common 1-1/4" axle used in competitive karting.


Common Applications:

  • Axle bearing support – Mount on either side of axle bearings to reduce movement and lateral flex.
  • Wheel hub stabilization – Install inside the rear wheel hubs to limit flex and help increase mechanical grip.
  • Brake & sprocket alignment – Use on both sides of the brake hub and sprocket carrier to maintain proper spacing and reduce part shift under load.


Split Collar Specifications:

  • Inside Diameter (ID): 1-1/4"
  • Outside Diameter (OD): ~2.00"
  • Keyway Width: 1/4"
  • Material: CNC-machined aluminum
  • Design: Two-piece with dual bolt clamp
  • Fitment: Standard for 1-1/4" racing kart axles


Key Features:

  • Split design allows for easy installation and removal without axle disassembly.
  • Even clamping force prevents shaft damage or ovaling
  • Lightweight and corrosion-resistant aluminum construction
  • Machined keyway for increased torque resistance
  • Designed specifically for high-performance kart and mower chassis setups

Fitment Tip: Always confirm your axle diameter and key size before ordering for optimal compatibility.
