Overview
The Hot Racing Aluminum 25T Double-Clamp 5mm Off-Set Servo Arm is a precision steering horn for racers and bashers running 25-spline servos from Futaba, Traxxas, Savox, Orion, or ProTek. CNC-machined from 6061-T6 aluminum and black anodized, this servo horn features a 5mm offset arm geometry that helps optimize steering linkage angles for cleaner Ackermann and improved bump-steer characteristics.
The double-clamping locking design grips the servo spline securely with no slop, while two M3 linkage holes (16mm and 20mm centers) provide tuning flexibility for various steering geometries.
Key Features
- CNC-machined 6061-T6 aluminum construction
- Black anodized finish
- Double-clamping locking design — zero spline slop
- 5mm off-set arm geometry
- Two M3 linkage holes (16mm and 20mm from spline)
Performance Benefits
- Optimized linkage geometry via 5mm off-set
- Consistent, slop-free steering feel
- Two linkage hole options for steering rate tuning
- Long service life — won't strip the servo spline
Usage Notes
Apply blue thread-locker to the M2.5 x 4mm clamp screw. Choose the appropriate linkage hole based on desired steering rate (closer hole = slower steering, more torque; farther hole = faster steering, less torque). Verify steering geometry after installation.
