HRNSG35M1 - 35t Steel Mod 1 Pinion Gear 5mm

This product is a hardened steel Mod 1 pinion gear engineered to provide durable, precise power transfer in large‑scale RC drivetrains. The CNC machined steel construction increases resistance to wear and tooth stripping under high torque and high speed brushless loads compared to stock or softer metal gears. A 35 tooth Mod 1 gear profile allows fine‑tuning of overall gear ratios when paired with compatible Mod 1 spur gears to optimize acceleration and top speed. The 5 mm bore size fits standard pinion shafts found in many 1/7 and 1/8 scale platforms. Precision cut teeth and a hardened finish help maintain smooth mesh and consistent drivetrain performance under demanding conditions.
