Upgrade your RC car, truck, or boat with the ShareGoo Metal Servo Horns! This 3-pack gives you durable, precision-made aluminum alloy arms that are way stronger than plastic stock parts. They're designed with a 25-tooth spline that fits Futaba, Savox, Emax, Power HD, MG995, MG996, and Xcore servos (just not Hitec or JR, so check your model!). Each horn has M3 threaded holes for easy linkage attachment, and the split-clamp design secures tightly onto your servo with the included bolt. With hole centers at 15mm and 18mm, and a total length of 31mm, they're perfect for 1/10 or 1/8 scale vehicles. The red aluminum looks slick and handles the stress of steering and throttle duties without flexing or stripping. Easy to install, built to last, and a must-have if you're serious about your RC performance!
