Rear wheel hub spacer kit for racing go karts. Ideal for adjusting the track width on the kart quickly and easily while also preventing hubs from slipping inward! For karts that have this chronic issue or have smaller wheel hubs, these kits are a fantastic idea.

These hub shim kits are available for both 50mm and 40mm axles.

Overview

Adjusting the track width of the rear wheel hubs on a racing kart can significantly affect the handling. Depending on the width of the rear axle, most karts are designed to accommodate significant hub overhang off of the edge of the axle. However, the further the hub hangs over the edge of the axle, the more likely it is to come loose and slip inward, or outward, due to the torque and force applied to the hub that now has less internal support from the axle.

Made from hardened aluminum alloy, the hub width shims within this kit by Kart Master help to solve this issue. Furthermore, by utilizing matched pairs that are color-coded adjusting rear track width becomes very simple! This makes trackside changes a snap - no more measuring with a tape measure.

Each Kart Master rear width adjustment shim kit comes with (14) total pieces - matched pair sets of spacers that are sized for various track width settings:

  • 1mm
  • 3mm
  • 5mm
  • 7mm
  • 10mm
  • 15mm
  • 20mm

Each kit is sold separately, with the spacers enclosed in a clear plastic cylinder with rubber end caps for easy removal and storage.
