Tamiya 51085 TB Evolution IV Upper Deck Chassis Brace  [51085]

Chassis Brace for TB Evolution IV

The Tamiya 51085 Upper Deck serves as a reinforced brace for the TB Evolution IV chassis, designed to reduce unwanted movement and produce steadier handling in competitive conditions.

Improved Steering Precision

With added support over the central chassis, this upper deck helps maintain suspension geometry under load so steering inputs translate more predictably to wheel motion.

Fitment Notes and Installation

Made to the TB Evo IV specification, the upper deck lines up with original mount points allowing a clean swap using standard RC toolkits. No additional custom work should be necessary.
