Serpent 909251 Aluminum Pulley Adaptor Light Pair  [SER909251]

Reduced mass pulley adaptors for quicker response

The Serpent 909251 Aluminum Pulley Adaptor Light pair is engineered to lower rotating mass and trim overall weight, helping 1/10 and 1/8 scale vehicles respond faster on acceleration. Machined from aluminum for consistent balance, these adaptors are suited to club and track use where every gram counts.

Triangulated outer profile to cut weight

The triangulated outer diameter removes excess material compared with a standard circular pulley, reducing rotational inertia and improving agility on corner exit. Designed to match Serpent fitment parameters, these adaptors integrate with existing pulley and belt setups.

Straightforward fit for multiple scales

Suitable for both 1/10th and 1/8th scale Serpent models, these adaptors install without major chassis changes and provide a simple drivetrain upgrade for racers and hobbyists alike.
