HRNSG23M1 - 23 Tooth Steel Mod 1 Pinion Gear 5mm

Built to handle demanding RC drivetrains, this steel Mod 1 pinion gear delivers increased strength and lasting performance compared to softer materials. The hardened steel construction resists wear and fatigue when meshing with compatible spur gears, helping maintain smooth power transfer in high‑load situations. Its 23‑tooth profile allows fine tuning of gear ratios for balanced acceleration and top speed, depending on your setup. A precision bore sized for 5 mm motor shafts ensures secure mounting and alignment, while the included set screw keeps it locked in place during operation. The compact design fits a variety of on‑road and off‑road models that use Mod 1 gearing. This gear helps reduce maintenance frequency and enhances drivetrain reliability. It also contributes to a more mechanically realistic and refined build feel overall.
