Serpent 804301 Aluminum 40T Rear Gear Diff Pulley - Precision Upgrade  [SER804301]

Precision machined 40T rear differential pulley

The Serpent 804301 Aluminum 40T Rear Gear Diff Pulley is manufactured to tighten drivetrain response while reducing unnecessary mass. Its aluminium construction provides a robust yet light replacement for standard pulleys.

Protective finish and hole pattern

The anodized surface improves resistance to wear and corrosion for longer service intervals. The side hole pattern reduces weight and allows dirt to be expelled during operation, helping to maintain consistent drivetrain performance.

Compatibility notes and typical use

Compatible with many rear diff arrangements, this 40T pulley suits racers and hobbyists seeking measurable drivetrain refinement. It is suitable for both competitive tuning sessions and routine component replacement.
