Axle D50 x 1030 mm, Type H

OTK Rear Axle – Type H (Hard)
Type H is a hard rear axle designed to reduce flex and free up the chassis under high-grip conditions. It minimizes rear-end binding and helps the kart rotate more easily when the track grip is extreme. The result is a more responsive, stable rear end that provides smooth, predictable handling and sharper control in corners.

Compatibility: Fits all OTK chassis with Ø50 mm rear axle (Tony Kart, Kosmic, Exprit, Redspeed, Gillard, EOS, and others).
Application / Position: Installed in standard OTK 50 mm bearings and hubs. Used on high-grip circuits or in hot conditions when the kart tends to stick or lose rotation.
Material: Made from OTK’s proprietary hardened axle steel alloy, engineered for maximum stiffness and consistent torsional control.
Installation / Use: Direct fit into OTK bearing carriers and hubs. No modification required. Check straightness regularly, especially after heavy contact or impacts.
Specifications & features: Hard axle with reduced flex. Frees up the rear on high-grip tracks, improves steering response, and maintains consistent stability under load. Ideal for competition use in grippy or hot track conditions.
