Component-Level Steering Adjustment for Tuners

The 3Racing 2.6mm aluminium single servo arm delivers a predictable contact point for linkage setup when used on Ko Propo and Sanwa servos. Its alloy construction reduces flex under load, helping drivers dial in consistent steering endpoints and response rates during setup sessions.

Intended Fit and Setup Scenarios

Built to interface with Ko Propo and Sanwa splines, this arm is suitable for drivers aiming to refine steering geometry on high-grip circuits or tight technical layouts. Use it where small changes to horn length or arm position are part of the tuning process.

Practical Fitting Notes for Race Prep

Ensure precise spline engagement and verify the arm sits perpendicular to the servo case at neutral. When installing, check linkage geometry for bump steer and confirm screw torque to prevent micro movement which can affect lap-to-lap consistency.

How does arm thickness affect steering feel?

Thickness influences stiffness and backlash. A 2.6mm arm reduces lateral flex compared to thinner options, improving predictability under load while keeping mass low enough for quick return characteristics.

What checks should I perform before a race?

Confirm spline seating, verify servo neutral, inspect for stripped teeth on both horn and servo, and ensure linkages are free from binding. Small slop here shows up as inconsistent steering on track.

Can I use this for progressive steering setups?

Yes. The arm provides a stable pivot for progressive throw adjustments and can be paired with adjustable linkages or dual-rate settings to tune steering aggressiveness without changing the horn.
