Lightweight Pulley for Sharper Acceleration

For racers and weekend tuners, the Serpent 903596 Pulley Adaptor trims rotating weight to support quicker rev response. Its 21T configuration is produced to maintain smooth engagement and reduce unnecessary drivetrain drag in common Serpent setups.

Better Power Transfer and Service Life

By cutting rotational inertia, the pulley adaptor helps the vehicle get on the power sooner and improves overall driveline efficiency. The unit is built to withstand repeated on-track use when installed and maintained correctly.

It can be used where pulley spacing and tooth count match the chassis. While benefits are seen on many platforms, confirm fitment with your specific model before fitting on high-impact off-road machines.
Keep the area clean during fitment, check seals and bearings for ingress protection, and use appropriate lubricants to reduce wear in harsh conditions.
Inspect the pulley during routine maintenance intervals, looking for wear, looseness, or belt misalignment, and address any issues to preserve drivetrain performance.
