The XRAY XB4'20 Graphite Center Upper Deck is built to lift the handling of your car. It is cut to accept a narrower slipper and a high-capacity centre differential, making it a solid choice for racers trimming their setup. Machined from premium graphite, the deck delivers strength and long life so your XB4'20 stays consistent across hard practice sessions and race days.
Graphite is popular with experienced drivers because it combines low weight with high stiffness. Fitting this upper deck reduces unwanted chassis flex and helps the car turn in more predictably, which matters when you are pushing for faster laps and tighter lines.
A practical upgrade for club racers wanting a durable, race-ready centre upper deck for the XB4'20.
