XRAY 301090 X4'26 Glass Fiber Upper Deck - Agile Flex Upgrade  [XR-301090]

Refined Control with XRAY Glass Fiber Deck

Experience superior handling with the XRAY 301090 X4'26 glass fiber upper deck, crafted to increase chassis flexibility across a variety of track surfaces. Made from durable 1.5mm glass fiber, this upper deck helps improve traction and front-end steering. The layout supports straightforward tuning so you can match setup to your driving preferences and track conditions.

Adjustable Flex Modes

The upper deck offers two distinct flex settings:

• Soft Setting: Use a single rear screw to maximise flex and sharpen steering feedback. Best for tight, technical tracks where quick turn-in is needed, though it may feel less stable under heavy throttle.
• Stiff Setting: Fit both rear screws to limit flex, giving stronger stability and easier driving. Ideal when you want reduced rotation through corners and more predictable mid-corner behaviour.
