The Kyosho UMW748 Short Steel Differential Shaft Set is designed for the RB7SS to provide tougher internals and steadier handling on low to mid grip surfaces. This set is well suited to routine servicing or to upgrade a race car for more consistent track performance.
The UMW748 shafts are formed from hardened steel to withstand routine stress and reduce wear. That solid construction offers reliable service life for drivers who log frequent running or compete regularly.
Configured with low to mid grip surfaces in mind, these shafts help manage traction and directional stability. Fitting them can lead to a more predictable handling balance and improved feedback from the car.
