Reliable aluminium servo arm for 3RACING 3RAC-HKS30/LB

The 3RACING 3.0mm Aluminium Single Servo Arm, compatible with Ko Propo and Sanwa systems, gives a tough alternative to factory plastic arms. Its light blue anodised coating adds a neat visual touch while standing up to regular use.

Best uses for this servo arm

Suited to both rally-style off-road and everyday touring, the rigid aluminium helps keep steering consistent across varied surfaces. Drivers will notice steadier inputs after upgrading from softer materials.

Installation and matching gear

Fitment with common Ko Propo and Sanwa splines makes swapping straightforward. Check link lengths and servo centring during install to ensure correct steering geometry after upgrade.

Do I need special tools to fit this arm?

No special tools are required; common hex drivers and a small spanner are usually enough to remove the old arm and fit this aluminium replacement.

Will this change my steering feel?

Yes, aluminium reduces flex compared to plastic, giving crisper steering response and better repeatability lap to lap.

How do I avoid over-tightening the spline?

Ensure the arm sits fully on the spline before tightening and use firm but controlled torque on the retaining screw to avoid stripping the servo spline.
