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

Optio spring kit for fine TT-01 Type-E setup

This Optio spring kit from 3Racing is a direct replacement set intended for TAMIYA TT-01 Type-E chassis codes noted as TT01-14/LB/V2. The springs fit the standard shock bodies and are used to modify suspension response and to trim ride height.

To fit the springs, remove the damper from the suspension assembly, compress the old spring using the shock collar if present, then swap in the Optio spring and rebuild the shock. Basic RC service tools such as a hex driver and small pliers are adequate for the task, with no extra machining required.

When tuning, pair spring selection with suitable shock oil and preload changes to control roll and weight transfer. Perform controlled test runs on a low-risk layout and inspect the spring seating on the shock retainer after each run.
