Race-Ready XRAY 301022 - X4F'25 Aluminum Flex Chassis Overview

The XRAY X4F'25 Aluminum Flex Chassis at 1.5mm thickness uses Swiss 7075 T6 material to give measurable gains in traction and more predictable steering feel. It is aimed at racers wanting a stable, responsive platform for low to medium grip carpet and higher grip asphalt layouts.

Chassis Profile and Cornering Behavior

With an 84mm overall width and a tapered lower edge, the chassis cuts down on excess ground contact when leaning through turns. That profile helps maintain speed and directional control where precision matters.

Fasteners Needed and an Optional Screw Kit

Assembly calls for CNC-machined countersunk screws from HUDY Spring Steel in M3x5, M3x8, and M3x12 sizes. For a complete set, the optional screw kit #913300 includes 33 pieces of special 110 degree screws to simplify fitting.

What surfaces suit this chassis best?

It performs well on low to medium traction carpet and on asphalt with higher grip, offering a balanced feel across both surfaces.

Do I need special screws to fit this part?

Yes, use HUDY Spring Steel countersunk screws in M3x5, M3x8 and M3x12 for correct assembly and fitment.

Can this chassis help with understeer/oversteer tuning?

Its flex characteristics change weight transfer; small setup tweaks to toe and shock settings will help dial front or rear grip to suit your handling preference.
