HB TCXX Chassis Upper Plate 2.25mm - Arrowmax AM-TCXX-68761-V2  [AM-TCXX-68761-V2]

2.25mm Upper Plate by Arrowmax for HB TCXX

The Arrowmax AM-TCXX-68761-V2 upper plate is a 2.25mm aftermarket component designed specifically for HB TCXX frames. It replaces the stock top deck to alter chassis stiffness and influence handling characteristics while keeping the existing suspension geometry intact.

Fit and installation: this plate is intended to mate with the TCXX factory mounting points and uses the original screws and hardware. When installing, confirm that each hole lines up and that screw length does not press into electronics such as the ESC or the battery strap.

Tuning role: a thicker 2.25mm deck reduces chassis twist compared with thinner options, which can sharpen steering and stabilise the car under corner exit. Apply this part as part of gradual setup changes, pairing it with shock and anti-roll adjustments rather than swapping multiple items at once.

The AM-TCXX-68761-V2 is a useful tuning plate for drivers wanting less flex and crisper responses from HB TCXX cars; always verify fit and make incremental setup changes to measure impact.
