Kyosho UB040 Short Shafts Optimised for RB7.5

Owners wanting dependable drivetrain parts will appreciate the Kyosho UB040 Short Steel Differential Shaft Set. Engineered for the Ultima RB7.5, these shafts give reliable fitment and longer service life.

Durable Construction for Regular Use

The Kyosho UB040 shafts are manufactured from strong steel to withstand repeated runs and hard cornering. They are a practical upgrade for anyone replacing worn components or aiming for greater drivetrain resilience.

Designed for Straightforward Installation

These shafts are produced to match the Ultima RB7.5 geometry and are intended to be fitted with standard tools. Their robust profile reduces the chance of damage during heavy use.
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.

Can I use UB040 shafts with aftermarket diffs?

The UB040 is cut for the RB7.5 diff layout, so compatibility with aftermarket diffs depends on matching shaft lengths and mounting details.

How do I maintain these steel shafts?

Wipe them clean after wet or dirty runs, inspect for wear at contact points, and keep bearings serviced to extend shaft life.

Are replacement shafts worth it for casual drivers?

Yes, swapping to UB040 steel shafts can reduce breakage and lower the need for frequent repairs, making them a sensible investment even for non competitive users.

Do these shafts affect handling?

Shafts themselves don't change suspension geometry, but more consistent drivetrain behavior can improve predictability and control on track.
