XRay X426 - Aluminium Flex 1.5mm Edition

The XRAY X4 ’26 Aluminium Flex 1.5mm Edition (XR300044) advances the platform with weight savings, refined geometry and a host of new components for more consistent handling and easier setup across a wide range of track conditions. This edition forms part of the three-version X4 ’26 line-up, focusing on optimised flex characteristics with its aluminium 1.5mm configuration.

Key Features

• Three kit versions improve out-of-the-box performance for a wider range of track conditions
• 30g total weight savings without compromising durability, beneficial in spec class racing that requires larger battery packs
• All-new CFF2 lower suspension arms with integrated composite detailing maximise suspension rigidity and improve handling in all conditions
• New suspension geometry moves shocks further outboard to improve traction and steering response
• Refined ultra-low, consistent anti-roll bar mounting system improves function and ease of setup
• Smaller, lower-profile suspension pivot balls save weight and provide greater roll centre tunability
• All-new aluminium bulkheads complement the new suspension parts; a universal design at all four corners uses an interchangeable bulkhead for left-right and front-rear to reduce spares and simplify repairs
• Lower screw holes on the front and rear bulkheads feature countersinks allowing standard hardware for any chassis variation, improving durability while reducing costs
• All-new CFF upper arms with reduced flex from an optimised shape contribute to more consistent handling
• Link-style upper arms enhance steering response with additional adjustability compared to fixed moulded arms, providing maximum adjustability
• All-new carbon fibre upper clamps reduce overall weight, lowering CG while maintaining optimal chassis flex
• Multiple upper clamp mounting alternatives for different flex and handling characteristics
• Ultra-long link upper arms are easier to achieve with the new upper clamp design, providing an additional alternative to the standard upper arm length
• All-new narrow chassis accommodates the new suspension and bulkhead designs, including short and standard arms, as well as new shock holder positions
• All-new front bulkhead brace controls flex and handling characteristics, reducing the need for different front top deck types
• All-new ultra-lightweight, narrower front spool made from aluminium for low weight and a clean look
• All-new narrow, ultra-reliable and lightweight rear differential with pin system for outdrives
• All-new top decks optimise flex together with the new bulkheads, front brace and upper clamps
• Built-in suspension up-stops limit travel independently from the shock absorbers for easy fine tuning of front and rear suspension travel
• Smaller diff and spool bearings with eccentric holders reduce weight and lower CG
• All-new lightweight, ultra-durable rear carbon fibre body post holder
• All-new carbon fibre steering and ARS plates optimise geometry, flex and reduce unsprung weight

Bringing together lighter components, revised geometry and broader adjustability, the XRAY X4 ’26 Aluminium Flex 1.5mm Edition delivers a precise, responsive and tunable racing platform. Part number XR300044 from XRAY.
