ARC A11 Split Upper Deck Rear Graphite 2mm Stiffener - O-ARCP06 by Factory Pro  [FP-O-ARCP06]

Rear Split Upper Deck — Product Summary

This split upper deck rear is an aftermarket replacement shaped for the ARC A11 chassis and supplied as Factory Pro O-ARCP06. The part is a 2mm graphite plate formed to replace the standard rear upper deck section while keeping the split configuration used on the original ARC A11 design.

In use, the rear upper deck changes local torsional stiffness behind the radio tray and alters rear-end behaviour under cornering load. Fitting this graphite plate shifts the stiffness profile so tuners can refine mid to high speed rear traction and overall chassis balance without changing suspension geometry.

Installation is aimed at experienced builders: remove the existing rear upper deck, transfer any required mounts or spacers to the replacement plate, align the split sections, and secure with the original fasteners. Confirm clearance around the motor, servo, and radio tray before final tightening.

Tuning notes: increasing rear deck stiffness tends to reduce rear roll and can improve traction transition at corner exit, while a more compliant deck may help on low grip surfaces. Apply incremental changes and verify handling with test runs; treat this plate as one tool in a wider setup approach.
