Koswork Mod 1 M1 16T Lightweight Hardened Steel RC Pinion Gear 5mm Shaft - KOS03006-16

The Koswork KOS03006-16 is a Mod 1 16-tooth hardened steel pinion gear designed for RC cars running a 5mm motor shaft. Built from lightweight hardened steel, this pinion gear strikes a balance between reduced rotational mass and the durability needed to handle the stresses of competitive racing and bashing. It ships with a high-torque set screw for a secure, slip-free fit on the motor shaft, which is a detail that matters when you're running high-power setups where gear slippage can cost you performance or cause damage.

Key Features

• 16-tooth count suits mid-to-high speed gear ratio setups depending on your spur gear selection
• Hardened steel construction resists wear from repeated mesh contact under load
• Lightweight design reduces rotational inertia compared to standard steel pinions
• High-torque set screw included for a firm, slip-resistant mount on 5mm motor shafts
