XRAY X4F'25 Aluminum Flex Chassis Technical Summary

The XRAY X4F'25 1.5mm flex chassis is manufactured from Swiss 7075 T6 alloy to deliver consistent traction and crisper steering inputs. It suits drivers who want predictable handling on both low traction carpet and grippy asphalt circuits.

How the Shape Affects Grip

At 84mm wide with a tapered lower edge, the chassis reduces unwanted contact with the track during aggressive cornering. That geometry supports cleaner transitions and steadier speed through turns.

Hardware Requirements and Optional Set

Installation requires HUDY Spring Steel CNC countersunk screws in sizes M3x5, M3x8 and M3x12. For convenience, the optional screw set #913300 offers 33 special 110 degree screws to complete the fit.

Is this chassis a good match for club racing?

Yes, its balanced flex and material stability make it a reliable choice for club-level carpet and asphalt events.

What fasteners do I need to buy?

You should use HUDY Spring Steel M3x5, M3x8 and M3x12 countersunk screws; these ensure correct seating and strength.

Any setup advice for carpet tracks?

Try a slightly softer rear shock tune and a touch more steering ackerman to exploit the chassis flex on low grip carpet.

Will the chassis fit existing XB4 hardware?

It is designed for the XB4 series and aligns with the standard mounting points, though the correct HUDY screws are required for final assembly.
