Tamiya 54740 TA07 D-Parts - Medium Suspension Arm Kit OP-1740 for Tuners  [54740]

Gain smoother control on low-grip tracks

For racers tuning TA07 or TRF418/419 chassis, the Tamiya 54740 TA07 D-Parts (Suspension Arm / Medium Type) deliver a balanced stiffness option. These medium arms are designed to improve handling where traction is limited, helping the car remain composed through corners.

Composition and compatibility details

The medium composition fits between the softer fiberglass reinforced plastic of standard TA07 parts and the firmer carbon reinforced plastic used on TRF418/419 components. This middle option combines useful flex with solid durability for varied track conditions. Each package includes one front and one rear arm and fits TRF418-style suspension and the TRF419 D Parts (Item 54691).

Installation and setup advice

Because each package contains only one front and one rear arm, plan to purchase two packages to fully equip a car. After installation, verify clearances and perform low-traction test laps to evaluate how the medium arms change turn-in and midcorner grip before making other setup tweaks.
