The Factory Pro O-XCP022 front upper deck is an aftermarket graphite plate made to fit the XRAY X4F'25 front section. This 2.0mm graphite component is intended to influence stiffness distribution at the front of the chassis for drivers tuning handling and balance.
Installation is straightforward when the plate is aligned to the factory mounting points on the X4F'25 chassis. Confirm screw alignment and that the deck sits flat without impeding suspension movement. After fitting, inspect the area around the servo and steering rods for adequate clearance.
Track tuning notes: switching to a graphite front deck typically increases stiffness locally, which can sharpen steering response and alter corner entry feel. Implement changes incrementally and use a few practice laps to assess the effect with your current shock and tyre setup.
