Overview
Get a slop-free, professional steering setup with the Hot Racing Aluminum 5mm Off-Set 23-Spline Clamping Servo Arm. CNC-machined from aluminum and designed for the 23-tooth spline used by JR, Airtronics, and KO Propo servos, this clamping horn delivers the rock-solid connection precision drivers demand.
The 5mm off-set arm geometry helps optimize steering linkage angles for cleaner Ackermann and improved bump-steer characteristics — small details that add up to a noticeably better-feeling car at the track or on the trail.
Key Features
- CNC-machined aluminum construction
- 23-spline fitment (JR / Airtronics / KO Propo)
- 5mm off-set arm geometry
- Clamping design eliminates spline wear and slop

Usage Notes
Verify your servo uses the 23-tooth (JR/Airtronics/KO) spline before purchasing — this is NOT compatible with 25T servos. Apply removable thread-locker to the clamp screw during installation.
