Axle D50 x 1030 mm, Type HH

OTK Rear Axle – Type HH (Hardest)
Type HH is the stiffest rear axle in the OTK range, engineered for extreme grip conditions. It provides minimal flex and maximum rigidity, making it ideal for high-grip tracks where freeing the chassis is essential to prevent binding or oversteer. With its uncompromising stiffness, it ensures stability and precision even under the most demanding race situations.

Compatibility: Fits all OTK chassis with Ø50 mm rear axle (Tony Kart, Kosmic, Exprit, Redspeed, Gillard, EOS, and others).
Application / Position: Installed in standard 50 mm OTK bearing carriers and hubs. Used on high-grip or hot circuits where softer axles create binding or excessive rear traction.
Material: Manufactured from OTK’s hardest proprietary axle steel alloy, optimized for maximum torsional stiffness and durability.
Installation / Use: Direct fit into OTK hubs and bearings – no modification required. Clean and inspect for straightness after every session to maintain top performance.
Specifications & features: Hardest axle in the OTK range. Minimizes flex to free up chassis movement under extreme grip. Delivers stability, precision, and consistent handling for professional competition.
