Race-focused shaft upgrade - Tamiya 15440 - 60mm Hollow Stainless Steel Shaft for Mini 4WD  [15440]

Introducing the Tamiya 15440 60mm Hollow Stainless Shaft

The Tamiya 15440 60mm Hollow Stainless Shaft is a practical upgrade for Mini 4WD racers after better throttle response. Hollow stainless construction reduces rotating mass while keeping reliable strength for regular competition use.

Compatibility and Weight Reduction

These shafts are estimated to save about 1 gram compared with standard shafts, a small but useful reduction for racers chasing marginal gains. They fit a wide variety of chassis types, including Type 1, Type 3, Type 5, Super 1, FM, TZ, TZ-X, VS, and MS platforms.

Effect on Acceleration and Stability

Fitting the Tamiya 15440 shafts reduces rotational inertia, helping the motor accelerate the wheels more efficiently and aiding top speed on longer straights. The lighter drive-train can also smooth out handling during high-speed cornering, improving stability.
