HRSTRXF45M08 - 45t 32p Steel Spur Gear TRA Trx-4

Hardened steel 45‑tooth spur gear with a 32 pitch tooth profile designed for TRX‑4 scale RC drivetrains. It replaces stock nylon or composite spur gears to provide greater strength and wear resistance under high torque and harsh off‑road conditions. Precision‑cut teeth maintain accurate gear mesh with compatible pinions for smooth power transfer and reduced drivetrain lash.

• hardened steel construction for increased strength and durability compared with stock nylon spur gears

• 45‑tooth 32 p profile ensures compatibility with common 32 pitch pinion gear systems

• precision machined teeth maintain accurate gear mesh to reduce drivetrain noise and wear

• suitable for TRX‑4 and similar scale RC rock crawler and off‑road platforms

• black oxide finish helps resist corrosion and surface wear

• direct replacement design fits standard spur gear mounting interfaces

• balanced gear profile supports smoother power transfer at various speeds
