AR310758 Pinion Gear 18T 0.8mod 4x4 (ARAC7877)

This 18-tooth pinion gear, sized for a 0.8 modulus, is designed for four-wheel-drive RC systems. Built from a hard-wearing material, it delivers smooth, reliable gear operation even during fast, extreme action, helping maintain consistent power transfer in demanding conditions.

The gear features precisely machined teeth and a robust set screw for a secure fit. The tooth count is molded into the pinion boss for easy size recognition, and a matching M4 x 4mm set screw is included to complete installation.
