RC10B4/T4 Top Shaft - 9601

Restore the smooth, efficient power transfer of your classic 2WD transmission with this factory-replacement top shaft.

The top shaft is a critical component of the Team Associated stealth gearbox, acting as the direct link between your slipper clutch and the internal idler gear. Over time, high-power brushless motor setups or heavy landing impacts can wear down the teeth or stress the shaft, leading to drivetrain play or gear noise. Replacing your worn shaft keeps your transmission spinning freely and reliably.

Precision machined from high-strength steel, this genuine Associated Electrics replacement part ensures a precise mesh with your idler gear and a secure fit for your slipper clutch assembly. It is designed specifically for the B4, T4, and SC10 2WD platforms.

Pro-Tip: Whenever you replace a top shaft, always inspect your idler gear and the gearbox bearings. Installing a new shaft with worn-out bearings or chipped gear teeth can cause premature wear on your brand-new parts.
