ARC A11 Front Split Upper Deck 2mm Graphite - O-ARCP05 by Factory Pro  [FP-O-ARCP05]

Front split upper deck for ARC A11 chassis

This replacement front split upper deck is made to fit the ARC A11 chassis and is listed as O-ARCP05 from Factory Pro. The part is a 2mm graphite plate in a split layout designed to change local stiffness ahead of the front bulkhead.

The split design allows tuners to adjust front-end behaviour by changing stiffness separately on the left and right sides or by swapping to different deck thicknesses in modular setups. It is intended for 1/10 electric touring car use and for track tuning where small changes to chassis flex affect turn-in and front traction.

Fitment uses the ARC A11 factory mounting points; replace the stock front upper deck with this component using the same screw locations and hardware. After installation, check clearance around the servo and front suspension towers and verify steering geometry and bump steer during initial test runs.
