Strengthen Your RB7.5 with Kyosho UB040 Steel Shafts

For racers and weekend tuners who need a tougher drivetrain, the Kyosho UB040 Short Steel Differential Shaft Set is a practical choice. Built for the Ultima RB7.5 chassis, these shafts combine precision fit with improved resistance to wear.

Engineered for Racing and Frequent Running

The Kyosho UB040 set is made from quality steel to stand up to the demands of fast laps and repeated use. It is an efficient replacement for worn originals or a straightforward durability upgrade.

Fitment Notes and Service Tips

These shafts are cut to suit the Ultima RB7.5 layout and are intended to drop into the stock diff assembly. After installation, verify gear engagement and recheck after a few runs to ensure optimal performance.
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.

Is special tooling required to fit the UB040?

No specialised tools are usually required; standard hobby tools and a clean workspace are sufficient to replace the diff shafts on an RB7.5.

Will these shafts change the driveline angle?

They are machined to the same dimensions as the originals, so driveline geometry should remain unchanged when fitted correctly.

What should I check after fitting new shafts?

Confirm bearing fit, check for smooth rotation, and inspect gear mesh and diff preload after the first few runs to catch any settling issues early.
