HRNSG843 - 43t steel 48p Pinion Gear 5mm & 1/8

Steel 43‑tooth 48 pitch pinion gear engineered for hobby RC drivetrains requiring robust metal gearing. Precision machined from hardened steel and heat treated for wear resistance, this gear is designed to mesh cleanly with compatible spur gears while fitting both 5 mm and 1/8 in motor shafts used in a variety of 1/10‑scale and 1/8‑scale electric vehicles.

• 43 tooth count with 48 pitch specification for standard RC gear mesh.

• Hardened steel construction improves durability under high torque and high speed.

• Dual bore fitment accepts both 5 mm and 1/8 in motor shafts for versatile installation.

• Precision tooth profile ensures smooth engagement with 48 p spur gears.

• Heat treated finish increases resistance to wear and deformation.

• Balanced design reduces drivetrain vibration and noise.

• Suitable for use with brushed or brushless motors across multiple vehicle types.
