The Freeline KZ B-grade rear axle is a 50mm diameter, 2mm wall thickness, 1060mm length axle designed for KZ Shifter class karts. The B-grade rating indicates a stiffer flex profile, suited to high-grip track conditions where a more rigid rear end helps maintain traction and stability under heavy braking and acceleration. Manufactured by Freeline to OEM specification for Birel ART and associated chassis brands.

Buying advice: Axle grade selection is chassis and track-condition specific. B-grade is generally suited to grippy circuits; consider F-grade (softer) for lower-grip conditions or to improve rear release. Related: Freeline KZ F-grade Axle 50x2x1060 | Kart Axles.
