Precision Midshaft Upgrade for SRX4 Gen3

The Serpent 21T Midshaft Pulley is a focused replacement part for the SRX4 Gen3 that aims to improve drivetrain efficiency. It helps smooth torque delivery during acceleration and keeps the car predictable under heavy throttle, which is useful for both club racing and serious practice sessions.

Durable Construction with Accurate Engagement

This pulley features a 21-tooth profile designed to keep gear engagement precise and reduce power loss through slippage. The robust build supports repeated track use and helps preserve drivetrain components over time.

Quick Swap Installation

Designed to slot into the SRX4 Gen3 midshaft assembly, the part allows a quick replacement without extensive adjustments. It is suitable for racers who want a simple, reliable upgrade to their drivetrain layout.

Will this pulley change handling or balance?

The pulley is intended as a direct replacement and primarily changes power transfer characteristics rather than chassis balance. Handling changes are usually subtle and tied to drivetrain response.

What should I check after fitting the pulley?

Verify alignment, ensure set screws or retaining hardware are secure, and spin the shaft to check for smooth operation before running.

Are upgrades needed elsewhere when fitting this pulley?

In most cases no additional upgrades are required, though pairing the pulley with well maintained bearings and a tuned drivetrain gives the best results.
