The Serpent 500506 3-Gear Transmission Upgrade is a targeted improvement for the SRX2 MH chassis that tightens drivetrain behavior and improves robustness. It helps deliver a more consistent power curve and better handling feel under load.
Components are precision-cut to minimise backlash and lower friction, which contributes to more direct drive response and longer service intervals. The construction is aimed at hobbyists who push setups during club and regional racing.
Made to mate with SRX2 MH parts, the transmission mounts in place of the stock unit with a straightforward installation. Double-check bearing seating and gear mesh, and confirm alignment to avoid premature wear.
