Fine-Tune Your RC with the Kyosho OTW159

The Kyosho OTW159 lightweight gear shaft is a precision-machined upgrade made to refine the performance of Optima and Ultima models. Built from high-strength 7075 aluminum, it reduces rotating mass for quicker throttle response while remaining durable under hard use.

Lightweight Strength for Racing

Using 7075 aluminum gives this shaft an excellent strength-to-weight ratio, helping lower unsprung and drivetrain weight without sacrificing toughness. That weight saving translates into more responsive handling and quicker acceleration on race day.

Fitment and Installation Guidance

Designed specifically for the Legendary Series Optima and Ultima cars, the Kyosho OTW159 installs as a direct replacement where specified. It is suitable for routine maintenance or as a targeted upgrade for competitive setups.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will Kyosho OTW159 fit other drivetrain layouts?

The OTW159 is modelled for Optima and Ultima fitment; it may work in other Kyosho cars with matching shaft diameters and lengths, but always compare specs before buying.

How does 7075 aluminum affect durability?

7075 aluminium offers high tensile strength and good fatigue resistance, so the shaft withstands race stresses better than softer alloys while staying light.

Any tips for installing the shaft?

Clean mating surfaces, check for proper bearing fit, and use thread locker where recommended. Verify alignment before final tightening to avoid premature wear.
