Tamiya 42233 TRF417X Upper Deck 2.25mm Race Tune  [42233]

Stiffen Your TRF417 Chassis with Accuracy

The Tamiya 42233 TRF417X Upper Deck is a 2.25mm thick replacement plate designed to reduce chassis flex and sharpen handling. It provides a straightforward way to alter torsional characteristics without complex mods.

Sharper Cornering and Consistency

Fitting this thicker upper deck raises torsional rigidity, which helps the car hold its line through bends and improves consistency lap after lap. It is especially useful when dialing in steering balance on flat, high-grip surfaces.

Compatibility Details and Simple Fitment

Designed to match the TRF417 family, the deck uses existing mounting points for a clean fit. Installation is simple and reversible, letting you test different deck thicknesses quickly during set-up sessions.
