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

Upper Deck for HB TCXX (1.75mm)

This Upper Deck is an RC-scale replacement part produced by Arrowmax for the HB TCXX touring car platform. It is offered as a 1.75mm option intended to change the chassis mid-section stiffness and influence handling balance when used in conventional HB TCXX setups. The description focuses on fitment, the deck's role in tuning, and practical installation considerations relevant to 1/10 electric touring car use.

Compatibility: designed for use on Hot Bodies / HB TCXX chassis configurations where the factory upper deck is removed or swapped. Do not use this part on non-RC or full-size vehicles.

Installation notes: the Upper Deck mounts to the standard TCXX bulkhead points and works with the stock mounting hardware. For a controlled setup change, replace the OEM deck with this 1.75mm unit and evaluate changes to understeer/oversteer balance using incremental shock and anti-roll adjustments rather than altering multiple components at once.

Tuning role: choosing a 1.75mm upper deck is a mid-level stiffness choice intended to reduce chassis flex through the center section, which can tighten turn-in and provide a slightly more consistent throttle response across corner exits. Pairing with spring and damper tuning helps isolate the deck's effect from suspension changes.

Use this Upper Deck when you want a measurable change in mid-chassis stiffness without extensive chassis modification; assess handling on-track and combine with small damping tweaks for predictable results.
