Precision Titanium Kingpin Ball for Sharper Steering

The Yokomo RP-102A Titanium Φ4.8 Kingpin Ball is produced to improve BD9 steering dynamics. Titanium construction lowers weight at critical suspension points, trimming unsprung mass to give a livelier front end and cleaner entry into corners.

Material Advantages for Track Parts

Titanium's high strength-to-weight ratio means components stay durable while shedding grams where it counts. Installing the Yokomo RP-102A can make steering inputs feel more direct and predictable without adding fragility.

Accurate Fitment for BD9 Chassis

Built to suit BD9 geometry, these kingpin balls slot into the original mounting locations and maintain correct alignment. The reduced rotating mass helps retain speed through transitions and improves the car's reaction to steering corrections.
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.

Is titanium likely to corrode in normal use?

Titanium resists corrosion well under typical RC conditions. Rinse and dry the part after exposure to dust or moisture to keep it performing.

Will I feel a noticeable weight saving on the track?

The saving is concentrated at pivot points, so handling becomes crisper even though overall vehicle weight change is small. Drivers often notice sharper turn-in and improved mid-corner response.

Can this part be used on rough surfaces or only smooth tarmac?

It is suitable for a range of surfaces, but the handling gains are most apparent on smooth circuit surfaces where precise steering inputs matter most.
