The Serpent 401533 nylon spool is a precisely made component intended for use in the 411 chassis to improve consistency under drive. The nylon construction keeps the unit light while maintaining resistance to everyday wear.
Fitting this spool helps equalise torque delivery to both rear wheels which reduces unpredictable breaks in traction during cornering. The reduced rotational weight assists with faster acceleration and a sharper feel through direction changes.
The spool installs into the Serpent 411 without modification and works with the optional aluminium bushing for extra stability. For casual running the bushing can be omitted, but for competitive or modified cars fitting the bushing is a sensible precaution.
