Upgrading your RC car and tired of plastic servo arms that slip or strip? This 3-piece set of metal servo arm horns is a game-changer. Designed for Wltoys models like the A949, A959-B, A969, A979, and K929, these 25-tooth arms are CNC machined from aluminum alloy—so they’re strong, lightweight (about 3.75g each), and won’t wear out like plastic. The blue anodized finish looks cool and adds a bit of personal flair under the chassis.

Each horn has three mounting positions: 13mm, 16mm, and 19mm from hole center to hole center, giving you flexibility in your steering setup. They come with locking bolts to secure them tightly to the servo, preventing slip even during aggressive driving. The size is compact (about 26 x 8 x 7mm), so they fit nicely in 1/10 or 1/8 scale models. Installation is straightforward—just swap out the old plastic arm, bolt on the new one, and you’re ready for better control and durability. Whether you’re bashing around or racing, these metal arms handle the stress and keep your steering precise. A simple, affordable upgrade that makes a real difference.
