The Kyosho UM584 servo saver shaft set is crafted for the Ultima SB to tighten up steering response and improve wheel feedback on rough surfaces. It suits drivers aiming for steadier handling in challenging conditions.
Engineered to cope with repeated impacts and rough track conditions, this shaft set helps limit wear in the steering train. That delivers more predictable behaviour lap after lap.
The kit matches Ultima SB steering mounts to allow a smooth installation and preserve the original linkage geometry. It is an effective option for hobbyists wanting better control with minimal fuss.
