TAMIYA TT-01 Type-E Optio Spring Set - TT01-14/V2/OP by 3Racing  [TT01-14/V2/OP]

Optio springs tuned for TT-01 Type-E handling

These Optio shock springs are an aftermarket replacement set from 3Racing designed to fit TAMIYA TT-01 Type-E variants listed as TT01-14/LB/V2. They install into the model's standard dampers as a direct swap to change suspension stiffness and allow fine adjustment of ride height.

For installation, remove the shock from the suspension arm, compress the spring using the shock threaded collar if fitted, then exchange the factory spring for the Optio unit and reassemble. Typical RC maintenance tools such as a hex driver and small pliers are all that is required; no machining or special fixtures are necessary.

In practice, changing these springs affects body roll, pitch and weight transfer on the TT-01 chassis. Combine spring swaps with appropriate shock oil and preload adjustments to achieve consistent handling. Always trial new settings on a safe, compact layout and confirm correct seating on the shock retainer after fitment.
