Refine Power Delivery with Serpent 120159

The Serpent 120159 - 48P 21T Aluminum Motor Pinion Gear is manufactured from quality aluminium to provide a dependable pinion for your RC. The 48-pitch, 21-tooth format ensures steady tooth contact and consistent transmission of torque, making it useful for tuning and racing applications.

Precision and Reduced Inertia

Hardened aluminium offers a good balance of strength and lightness; the Serpent 120159 pinion trims rotational inertia which helps with throttle response and can modestly improve runtime. It is designed to cope with demanding track sessions when installed correctly.

Selection and Simple Installation

Intended for systems using 48-pitch gears, the 21-tooth size is a versatile choice for many setups. Verify motor shaft fit and set an appropriate mesh to protect gear teeth and bearings from undue stress.

Measure your motor shaft diameter and confirm the pinion bore matches; the pinion is for 48-pitch systems so also check the spur gear pitch before purchasing.
Yes, but on very high power or sustained heavy loads you should monitor wear and consider regular inspections, as aluminium behaves differently to hardened steel under extreme conditions.
Keep the gear mesh correctly set, clean debris after off-road use, and check the set screw and bore for any signs of loosening or wear during routine maintenance.
Changing the pinion tooth count affects final drive; you may want to adjust the spur or pinion to suit tighter tracks or long straights to optimise performance.
