Yokomo RP-117 precision king pin upgrade for MS1.0

The Yokomo RP-117 titanium king pin ball is built for the MS1.0 chassis to deliver a precise steering upgrade that sharpens response. Machined from lightweight titanium, this ball lowers rotating mass and helps the model react faster. Its profile is 1mm taller than standard parts, which lets tuners change the roll center to chase improved grip and cornering balance.

Design details that sharpen handling

The RP-117 reduces unsprung weight while lifting the roll centre, a combo that can increase traction and lateral stability on technical tracks. Racers can use this part when dialing in front-end bite or when seeking a more predictable turn-in.

Fitment and simple installation notes

This king pin ball fits the MSR-010 chassis for a straightforward swap into existing steering assemblies. Installation is simple for runners doing routine upgrades or carrying out a quick setup change between events.
Remark :
Due to limited stock availability, please notice that some Yokomo 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.

How will the 1mm height change affect front end behaviour?

Raising the ball by 1mm moves the roll centre slightly, which typically increases front grip and can make turn-in feel stronger. Expect a small but usable difference when tuning the car.

Do I need special tools to fit the RP-117?

No special tools are required beyond common RC hand tools. A clean workspace and basic hex drivers make the swap quick and repeatable.

Is titanium worth it compared to stock steel balls?

Titanium saves weight and resists corrosion while keeping strength. For racers chasing small handling gains and longevity, it is a practical upgrade.
