Overview of the SRX2 Gen3 Topshaft

Specifically engineered for the SRX2 Gen3, the Serpent 500788 21T Aluminum Topshaft offers a tidy blend of lightness and stiffness. Its 21-tooth profile helps maintain smooth gear engagement while cutting unnecessary weight from the drivetrain setup.

Why Choose Aluminum for Your Topshaft

Aluminum reduces rotating inertia and can sharpen throttle response compared to heavier stock parts. The Serpent 500788 holds up well under race conditions, giving a noticeable improvement in transient acceleration and overall drivetrain stability.

Compatibility and Quick Installation Guide

Designed to drop into the SRX2 Gen3 layout, the Serpent 500788 installs with routine disassembly and reassembly steps. Verify bearing seating and align gear meshes during fitment to ensure optimal drivetrain efficiency and minimal noise.

Can I run this on carpet or tarmac setups?

Yes, the lower rotating mass helps in both low-traction carpet and high-traction tarmac environments by improving response, though other setup tweaks will also be needed per surface.

Is the 21T tooth count standard for SRX2 gearing?

A 21T topshaft is common for certain gear ratios on SRX2 Gen3. Confirm your overall gear mesh and pinion/spur choices before swapping to keep final drive ratios in your desired range.

Should I change bearings when fitting this topshaft?

Inspect bearings for wear and replace if there is play. Fresh bearings help the Serpent 500788 perform at its best and reduce vibration and heat build-up.
