Axle D50 x 1000 mm, Type HH, Short

OTK Rear Axle – Type HH Short (Hardest – 1000 mm)
Type HH Short is the short version of OTK’s hardest rear axle, offering the highest stiffness available in the range. With the same extreme rigidity as the standard Type HH, but reduced length (1000 mm), it provides an even freer chassis and quicker rear-end release. Designed for extreme grip conditions, it allows the kart to rotate without binding while maintaining stability and control during acceleration and cornering.

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 circuits where maximum chassis release and precise response are required – typically for finals or very grippy track conditions.
Material: Made from OTK’s hardest proprietary hardened axle steel alloy, ensuring maximum torsional stiffness and durability.
Installation / Use: Direct fit into OTK bearings and hubs. No modification required. Check for straightness and clean after use to maintain consistent accuracy and performance.
Specifications & features: Short (1000 mm) rear axle with identical stiffness to Type HH. Delivers maximum chassis freedom and response. Reduces binding under extreme grip and provides stable, precise handling. Ideal for professional racing use.
