Bashing your Arrma 3S BLX truck hard and stripping plastic differential gears? Upgrade to this metal gear set! It includes both front and rear differential assemblies (the gears inside the diff), made from high-quality steel with a hard anodic oxidation coating for strength and rust resistance. They're designed to fit 1/10 scale models like the Big Rock 3S BLX, Vorteks 3S BLX, Granite 3S BLX, Senton 3S BLX, and their Mega 550 versions, plus 1/8 scale Infraction 3S BLX, Typhon 3S BLX, and Vendetta 3S BLX. The gears have specially designed strengthening cut-outs to handle crashes and big jumps better than stock. Installation is straightforward if you're comfortable taking apart your diffs—just swap the old gears for these metal ones. You'll get smoother power transfer, less wear, and way more durability for aggressive driving. Keep your RC running strong and save money on replacements. A popular upgrade for Arrma fans who push their trucks to the limit!
