The steering servo horn on a big 1/5th model takes a real beating. This upgraded strong aluminum version will ensure the servo horn does not strip or snap and comes in a cool orange finish to match the Yama buggy other aluminium parts and rims. Note- This servo horn is for the latest servos with a large 17 spline output. It does not fit the original smaller 25 spline servos, for those please purchase YSERVOHORN
