3RACING 3RAC-H2325/BK Sanwa Single Arm 3.0mm V2 Racing  [3RAC-H2325/BK]

Race-focused geometry for the 3RACING Sanwa 3.0mm V2

The 3RACING Sanwa Single Arm 3.0mm V2 provides a fixed 25mm distance from the servo gear hole to the ball end, allowing precise setup of steering angles and end points. The black anodized finish aids clean installation and minimal visual interference on race cars.

Consistent steering input for setup work

This arm translates servo motion into repeatable steering movement, which is vital when tuning toe, ackermann, and steering throw for lap time improvements. Its construction supports repeated adjustment without excessive play.

Application and tuning notes

Suitable for competitive setups, the arm fits servos with a 3.0mm output shaft and pairs with standard ball end linkages. When setting geometry, verify the 25mm centre measurement and adjust tie rod length to achieve the desired steering ratio and neutral alignment.
