Tamiya TA01 Alloy Main Drive Shaft Set TA1025 by GPM  [TA1025]

TA01 alloy shaft replacement

The TA1025 alloy main drive shaft set is an aftermarket replacement for the Tamiya TA01 chassis that gives a tougher drivetrain link and better wear resistance than the stock plastic shafts. These alloy units are intended to reduce play between the gearbox output and the rest of the drivetrain for more consistent power transfer.

Installation is straightforward for anyone familiar with TA01 servicing: remove the gearbox output parts, swap the original shafts for the alloy pieces, and check clearances so nothing binds. Reuse the vehicle fasteners where applicable and inspect the spur gear and bearings for wear before finishing the job.

From a tuning point of view, alloy shafts are a practical upgrade when you want repeatable drivetrain response under heavier loads or frequent running. They do not alter gear ratios or motor output, but they lower flex and the chance of shaft deformation that can occur with softer stock components.

Choose these shafts as a direct-fit durability upgrade, and pair the swap with a quick check of gears and bearings to ensure smooth, reliable operation on track or during club practice.
