HB TCXX Upper Deck 1.75mm Tuning Plate - Arrowmax AM-TCXX-68484-V2  [AM-TCXX-68484-V2]

Arrowmax Upper Deck for HB TCXX 1.75mm

This upper deck is an aftermarket replacement from Arrowmax for the HB TCXX touring chassis. The 1.75mm plate is intended to modify stiffness through the center section of the chassis and influence handling balance in typical HB TCXX setups. Notes below cover fitment, the deck's role in tuning, and practical installation tips for 1/10 electric touring car use.

Compatibility: built to match Hot Bodies / HB TCXX mounting patterns so it fits when the factory upper deck is removed or swapped. Confirm your chassis layout before purchasing to ensure correct alignment.

Installation notes: the Upper Deck secures to the standard TCXX bulkhead mounting points and is compatible with the stock hardware. For predictable results, swap the OEM deck for this 1.75mm unit and make small suspension adjustments first rather than changing multiple components at once.

Tuning role: the 1.75mm thickness is a mid-stiffness choice that reduces mid-chassis flex, which can sharpen turn-in and stabilise throttle response on corner exit. Combine this deck with measured spring and damper tuning to separate chassis stiffness effects from suspension changes.

Use this upper deck when you want a clear mid-chassis stiffness change without extensive modifications; test on-track and tweak damping to dial in the final balance.
