HB TCXX Chassis Upper Deck 2.5mm - Arrowmax AM-TCXX-68761  [AM-TCXX-68761]

Chassis stiffening upper deck for HB TCXX

The Arrowmax AM-TCXX-68761 upper deck is a 2.5mm aftermarket top-plate designed for the HB TCXX platform. Intended as a tuning component, this deck alters chassis rigidity and helps modify the car's top-plate geometry rather than affecting electronics or the drivetrain.

Install this part when testing a different top-plate stiffness on Hot Bodies TCXX chassis to determine handling changes. During installation, ensure servo clearance, tidy ESC wiring, and check shock tower fitment, then retorque fasteners after the first run. The greater thickness compared to thinner stock decks will change flex and weight transfer behaviour, so expect handling differences when swapped in.

A straightforward tuning component for HB TCXX owners who want to experiment with chassis stiffness at practice or race meetings.
