SRX2 Gen3 Topshaft Summary

The Serpent 500788 21T Aluminum Topshaft is crafted for hobbyists who want a reliable weight saving in the SRX2 Gen3 drivetrain. Machined from durable aluminium, the component aims to balance toughness with lower inertia for sharper on-track reactions.

Advantages of an Aluminium Topshaft

Switching to an aluminium topshaft reduces unsprung rotating mass and often improves throttle feel. The 21-tooth Serpent 500788 gives consistent meshing characteristics that support predictable power delivery under load.

Installation Tips and Fitment Advice

Installation on SRX2 Gen3 chassis is direct when following standard assembly practices. Pay attention to gear mesh, bearing alignment and lubrication to keep the Serpent 500788 running smoothly and to avoid premature wear.

Will this topshaft alter my gear ratio?

No, the tooth count determines mesh characteristics rather than final ratio by itself. Final drive depends on the spur and pinion combination you use with the SRX2 Gen3.

Is aluminium more brittle than steel for this part?

Aluminium offers less weight and adequate strength for normal racing loads. Proper setup and avoiding severe impacts will keep the Serpent 500788 functioning well; heavy crash use may still favour steel for ultimate toughness.

How often should I inspect the topshaft?

Check the topshaft each time you service the gearbox or after heavy sessions. Look for signs of wear at the teeth and mounting points and confirm bearings run true.

Can I polish or anodise this part?

Surface finishes can be applied, but ensure dimensions remain within tolerance. Cosmetic changes should not affect fitment as long as machining specs are respected.
