Kart Master 40mm Wheel Hub Aluminum Axle Spacer Kit

This aluminum axle spacer kit is a perfect fit for most 40mm hubs. Even if the hub loosens up, it effectively prevents the wheel hub from sliding. It's an excellent choice for DD2 karts. The kit includes 2 pieces each of 3mm, 5mm, 7mm, 10mm, 15mm, and 20mm spacers. The spacer has an outer diameter (OD) of 39.85mm and an inner diameter (ID) of 35mm.

Using this axle spacer kit is easy. First, make sure your kart has a 40mm wheel hub. Then, select the appropriate spacer size according to your needs. Install the spacer between the wheel hub and other parts to prevent the hub from sliding. When handling the spacers, be careful not to scratch them. After each use, it's a good idea to clean the spacers with a dry cloth. Store them in a dry place to avoid rust. If you notice any damage to the spacers, replace them immediately for safe operation.
