About this Product
The Senzo Rear Axle 50mm 1020mm is a high-quality performance axle designed specifically for Freeline chassis. Engineered for strength, precision, and consistency, this axle helps optimise rear-end grip and handling characteristics across a wide range of track conditions.
It ensures secure fitment of hubs and brake components while delivering the reliability required for competitive karting.
Axle stiffness is one of the most effective tuning tools in a kart setup. A softer axle flexes more, increasing rear traction — ideal when the track is green, cold, or low on rubber. A harder axle reduces flex and limits grip, which prevents the kart from being over-driven on high-grip or rubbered-in surfaces. Choosing the right grade for your conditions can make a significant lap time difference.
