The Exotek TLR 22 Aluminum HD Servo Horn is a machined aluminum upgrade for the TLR 22 family of models. This specially designed heavy duty clamping servo horn matches the dimensions of the stock 22 series servo horn (3mm style ball stud) so now you have great fit and correct geometry for robust steering and performance. Also excellent for other 1/10 brand models- just check the dimensions in the photo above for compatibility. Large M2.5 clamping screw included. For 25 spline servos only (Futaba, Savox, new Hitec, Protek etc).
