Specialist Tamiya 54740 TA07 Medium Suspension Arms D-Parts OP-1740  [54740]

Balance your TA07 with medium flex arms

If you want to tune a TA07 or a TRF418/419 chassis for looser conditions, the Tamiya 54740 TA07 D-Parts (Suspension Arm / Medium Type) give a middle-ground option. The medium flex improves predictability when traction is low, helping you keep lines tighter and lap times consistent.

Material choice and what fits

The medium material bridges softer fiberglass reinforced plastic found on standard TA07 pieces and the firmer carbon reinforced plastic used by TRF418/419 parts. That compromise yields usable flex plus good resilience for a range of surfaces. The set includes one front and one rear arm and is compatible with TRF418-style suspension and TRF419 D Parts (Item 54691).

Practical installation notes

Note that each package supplies one front and one rear arm only, so buy two packs to equip an entire car. After fitting, inspect pivots and clearances, then run a brief test session on a low-grip area to confirm the behaviour before further setup changes.
