XRAY X4 Aftermarket Split Upper Deck for Setup - Factory Pro O-XCP011  [FP-O-XCP011]

Upper deck functions and compatibility notes

This Factory Pro accessory, sold as Factory Pro O-XCP011, is a split upper deck designed for use with the XRAY X4 chassis to alter flex characteristics and provide alternate mounting arrangements for setup experimentation rather than serving as a structural replacement.

The two-part construction separates left and right upper deck sections so drivers can fine-tune torsional stiffness and centre compliance without modifying the lower plate or bulkhead positions. Fitting the set generally requires partial removal of the top assembly and uses the XRAY X4's existing mounting points and screws.

Keep in mind this is an aftermarket spare specific to the XRAY X4 platform, aimed at tuning handling on carpet and asphalt surfaces common in 1/10 touring racing.

For competitive builders this Factory Pro O-XCP011 split deck is a straightforward way to test chassis balance and flex effects; always confirm part fit for your X4 revision and follow standard fitment practice.
