Upgrade your BD9 setup with the Yokomo RP-101MHA Titanium Φ4.8 Rod End Ball, crafted for precision in upper arms and tie rods. This M size unit measures 13.0mm in length and uses lightweight titanium to cut rotating mass at the top end of the chassis, helping the car respond quicker during direction changes.
Titanium delivers a high strength-to-weight ratio and a smooth finish that reduces friction at linkages. Installing these rod end balls yields crisper steering feel and consistent movement through the suspension travel, which helps with repeatable lap times.
Lowering weight on the upper chassis aids transient response and balance without sacrificing durability. These rod end balls are a practical tuning part for racers aiming to sharpen turn-in and mid-corner stability.
