Serpent 909251 Lightweight Aluminum Pulley Adaptors (2pcs)  [SER909251]

Lightweight adaptors for improved drivetrain response

The Serpent 909251 Aluminum Pulley Adaptor Light set is designed to lower rotating mass in 1/10 and 1/8 scale cars, helping to sharpen throttle response and transient handling. Manufactured from aluminium to offer a balance of lightness and serviceability for regular track sessions.

Triangulated outer form reduces rotational inertia

The triangulated outer form eliminates unnecessary material compared with a full circular profile, decreasing rotational inertia to aid acceleration and direction changes. These adaptors are made to align with Serpent pulley geometry for a neat fit.

Simple upgrade for multiple Serpent scales

Compatible with both 1/10th and 1/8th Serpent models, the adaptors provide a straightforward route to reduce drivetrain mass without altering core setup or gearing, ideal for focused tuning work.
