TA05 centre pulley set 16T 17T 18T - TA05-21A by 3Racing  [TA05-21A]

Centre pulley solution for TA05

The TA05-21A centre bulk pulley set supplies interchangeable 16T, 17T and 18T pulleys specifically for the Tamiya TA05 series of 1/10 touring car chassis. It is intended as an RC replacement part to sit in the centre bulk area and pair with the original drivetrain components on TA05, TA-05IFS and TA05-R configurations.

Only the listed TA05 variants are supported; the set is not suitable for unrelated chassis. The accessory enables quick changes to centre pulley tooth count so tuners can tweak acceleration, midrange and top speed balance without altering the gearbox casing or motor pinion. Expect alterations to final drive behaviour rather than new mechanical demands.

To install, follow standard TA05 centre bulk access: remove the centre cover and any obstructing drive pieces, fit the selected 16T, 17T or 18T pulley, confirm proper gear mesh and alignment, then refit the original hardware. Manually rotate the driveline to check for smooth engagement before powering up.

This pulley set is a tuning item to be used with pinion, spur or ESC changes where required. It is for model-scale use only and not for real vehicle application.
