Race-Oriented Servo Arm for Precise Steering

The 3Racing 3.0 mm Aluminium Double Servo Arm is targeted at racers and tuners who demand low compliance in the steering system. Designed for direct compatibility with Ko Propo and Sanwa servo splines, the arm reduces flex for sharper response under load.

Stiffness and Compatibility Details

Manufactured from stiff aluminium to retain steering geometry during aggressive inputs, this double arm supports tighter servo-to-linkage control. The light blue surface finish provides surface protection while maintaining low mass. Fitment follows the common Ko Propo and Sanwa patterns for quick installation in race setups.

Tuning Benefits on Track

Using a 3.0 mm aluminium arm like this one helps maintain consistent control throw and centring across runs, assisting setup repeatability and predictable handling at higher speeds.

What improvements should I expect on lap times?

Expect crisper steering inputs and reduced compliance, which aids driver confidence and setup consistency. Lap improvement depends on overall setup and driver skill.

Are there any special installation tips for competition use?

Ensure the arm is mounted with correct centring and use thread locker where needed. Verify linkage geometry to avoid binding and to maintain linear steering response.

What maintenance is required after racing?

Inspect the arm for deformation, check fasteners for tightness, and confirm spline engagement. Replace if any wear or damage affects steering accuracy.
