Topshaft Details for SRX2 Gen3

The Serpent 500788 21T Aluminum Topshaft is a purpose made replacement for SRX2 Gen3 drivetrains. Precision machined from aluminium, it reduces rotating weight and supports cleaner power delivery during acceleration and deceleration phases on track.

Performance Gains from Aluminium Components

Aluminium topshafts help lower rotational inertia which can translate to sharper acceleration and improved handling feedback. The 21-tooth design of the Serpent 500788 provides stable engagement and reliable torque transfer for tuned setups.

Quick Fit and Service Advice

Installation onto SRX2 Gen3 is uncomplicated using routine tools. When fitting the Serpent 500788, verify bearing condition and set gear mesh correctly, then run a brief break-in with light loads to seat components for long term reliability.

Is this a race legal upgrade?

Race legality depends on event rules; mechanically the Serpent 500788 is a direct SRX2 Gen3 part, but check specific class regulations before competing.

What grease is best for the gears?

Use a light to medium viscosity gear grease suited to RC transmissions. Avoid over-greasing which can attract debris and cause drag on the Serpent 500788 assembly.

Can I use this with aftermarket spurs?

Yes, it will work with aftermarket spur gears so long as the mesh and alignment match SRX2 Gen3 specifications. Double check mesh clearance after installation.
