Serpent 903656 Low Friction Pulley Set for 977 Chassis Race Spec  [SER903656]

Reduce drivetrain drag on the Serpent 977

Built to refine the drivetrain of your Serpent 977, the Serpent 903656 Low Friction Pulley Set uses a composite material that gives a consistently smooth bearing surface. The kit contains six pulleys designed to lower friction and promote a more efficient power transfer. The composite is softer than typical black pulley compounds, so you may see a slightly higher wear rate, but many racers accept the trade for measurable reductions in drivetrain resistance.
