SRX2 Gen3 Topshaft Overview

The Serpent 500788 21T Aluminum Topshaft is a precision machined upgrade made for SRX2 Gen3 racers. Built from high grade aluminum, this topshaft cuts rotating mass while keeping the strength needed for aggressive driving, helping deliver crisper throttle response and steadier drivetrain behaviour on the track.

Benefits of Aluminum Shafts

Aluminum topshafts lower overall weight and reduce inertia in the drivetrain, which can improve acceleration and handling. The 21-tooth layout on the Serpent 500788 balances smooth engagement with reliable power transfer, making it a popular option for hobbyists tuning their gear ratios and responsiveness.

Fitment and Installation Notes

Fitting the Serpent 500788 topshaft into an SRX2 Gen3 is straightforward for anyone comfortable with basic RC maintenance. Ensure bearings and mating gears are clean and properly lubricated before assembly to maintain longevity and avoid premature wear under racing conditions.

Will this fit older SRX2 variants?

This topshaft is made specifically for SRX2 Gen3 geometry; older SRX2 models may have different mounting dimensions so check compatibility before swapping parts.

Do I need special tools to install it?

No special tools are required beyond basic RC toolkit items like hex drivers and a bearing press or driver. Clean the mating surfaces and use proper torque settings to avoid damage.

How should I maintain the topshaft?

Regular inspection, light lubrication of contact points, and keeping the surrounding area free of dirt will extend service life. Replace bearings if play develops.
