Arrowmax Ultra Mod 1 19T 5mm Shaft Spring Steel RC Pinion Gear 1/8 Scale - AM-601019

The Arrowmax AM-601019 is a Mod 1 19-tooth pinion gear designed for 1/8 scale buggy applications, built to fit a 5mm motor shaft. Made from spring steel, it's a direct replacement for worn or stripped pinions on 1/8 buggy and compatible electric RC platforms. The 19T tooth count places it in the mid-range of typical pinion selections, making it a common choice when tuning gear ratios for a balance of acceleration and top speed.

Key Features

• Mod 1 pitch — compatible with standard Mod 1 spur gears used widely across 1/8 scale RC buggies
• Spring steel construction provides greater durability and wear resistance compared to aluminium pinions
• 19-tooth count suits a mid-range gear ratio for general track and off-road use
• 5mm bore fits directly onto motors with a 5mm output shaft, common in brushless 1/8 scale setups
• Compact, precise cut ensures consistent mesh with Mod 1 spur gears to reduce drivetrain noise and heat
