XRay X4 26 - Carbon Edition

The XRay X4 '26 – Carbon Edition (XR300042) advances the X4 platform with significant weight savings, reworked suspension geometry and easier, more consistent tuning. With a 30g total reduction and a suite of new carbon fibre and aluminium components, it targets responsive, predictable handling across a wider range of track conditions.

Highlights include new CFF2™ lower arms with integrated composite detailing, link-style upper arms, refined anti-roll bar mounting and smaller, lower-profile pivot balls for greater roll centre tunability. Updated aluminium bulkheads, narrow chassis layout and optimised top decks simplify maintenance, improve flex control and lower overall mass and CG.

Key Features

• 3 kit versions improve out-of-the-box performance for a wider range of track conditions
• 30g of total weight savings without compromising durability, beneficial in spec classes that require 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 in all conditions
• Refined ultra-low and consistent anti-roll bar mounting system improves anti-roll bar function and ease of setup
• Smaller and 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, reducing spare parts count and simplifying repairs
• Lower screw holes on the front and rear bulkheads feature countersinks that allow using standard hardware for any chassis variation, improving durability while reducing costs
• All-new CFF™ upper arms with reduced flex from its optimised shape contribute to more consistent handling
• Link-style upper arms offer enhanced steering response with additional adjustability compared to fixed moulded arms, providing maximum adjustability out-of-the-box
• All-new carbon fibre upper clamps reduce overall weight, especially important due to their location, lowering CG while maintaining optimal chassis flex
• Multiple upper clamp mounting alternatives for different flex and handling characteristics
• Ultra-long link upper arms are made easier 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 the new shock holder mounting positions
• All-new front bulkhead brace controls flex and handling characteristics, and reduces the need for different front top deck types, reducing costs and simplifying setup
• All-new ultra-lightweight, narrower front spool is 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
• All-new built-in suspension up-stops limit suspension travel independently from the shock absorbers for easy fine tuning of the car’s front and rear suspension travel
• Smaller diff and spool bearings and eccentric bearing holders reduce weight and lower CG
• All-new lightweight and ultra-durable rear carbon fibre body post holder
• All-new carbon fibre steering and ARS plates optimise geometry, flex and reduce unsprung weight

Engineered for extensive adjustability straight from the box, the X4 '26 Carbon Edition blends precision, durability and tunability in a refined, lightweight package from XRay.
