Why the Top Shaft Matters

Compatibility: Specifically matched to the SRX4 Gen3 to ensure correct alignment and fitment.
Durability: Made to cope with intensive running and routine race day stress.
Performance: The 21T profile supports smooth power transfer for better throttle response and speed control.

Can I swap this top shaft into older SRX4 variants?

The 21T strikes a middle ground between torque and top speed, making it versatile for both short format sprints and longer race formats depending on gearing.
