XRAY 301030 - X4F 27 Aluminium Flex Chassis 1.5mm - Swiss 7075 T6  [XR-301030]

X4F 27 aluminium flex chassis

This X4F 27 aluminium flex chassis is an RC-scale 1.5mm plate designed for track use where grip is high. The plate delivers controlled flex to alter steering response and cornering behaviour without implying real vehicle use. Its narrow layout and tapered lower edges reduce the amount of chassis rubbing on the surface during cornering, helping to keep corner speed consistent on high-traction carpet and asphalt.

Manufactured from Swiss 7075 T6 aluminium and precision CNC-machined, the chassis emphasizes consistency across production pieces and durability under competitive track loads. The material and machining yield predictable flex characteristics that teams can dial into their setups for more precise handling adjustments.

Installation requires specific hardware for correct fit and function: HUDY Spring Steel countersunk screws #913305 M3x5 (4 pcs) must be used together with 4 pcs of shims #303118-C and 4 pcs of shims #301119-C. Follow the chassis mounting pattern exactly and use the stated screw and shim combination to achieve the intended ride height and preload on the chassis plate.

As a tuning component, this 1.5mm aluminium flex chassis is best used when increased traction demands a more responsive steering centre and stable corner speed; pairing the plate with the specified HUDY countersunk screws and shims ensures the chassis flex behaves as intended for precise setup work.
