Serpent 903571 21T Pulley Adaptor Overview

The Serpent 903571 Pulley Adaptor 21T is built to tighten up drivetrain action and deliver consistent gear engagement. Precision machined for minimal play, it suits both competitive racers and club-level hobbyists who want predictable throttle response.

Main Benefits

Durability: Machined from resilient material to withstand extended use and track wear.
Compatibility: Designed to fit a wide range of RC drivetrains when matched to the correct shaft and gear setup.
Performance: Improves transfer of motor torque to lower drivetrain backlash and smooth operation.

How do I check fitment for the Serpent 903571 adaptor?

Measure your shaft diameter and the mating pulley bore, and compare the adaptor dimensions to your existing parts. If you run a shim or set screw, verify clearance before final assembly.

What maintenance keeps the 21T adaptor working well?

Keep mating surfaces clean and free of grit, inspect for wear after heavy runs, and apply light lubrication to any interface where metal contacts metal to reduce corrosion and friction.

Can this adaptor affect gear ratio or speed?

The adaptor itself does not change tooth count on driven gears, but accurate seating can improve effective engagement which may slightly alter perceived acceleration and smoothness.
