XRay X4F 26 Chassis Kit (XR300205)

The XRay X4F 26 (XR300205) brings a host of 2026 updates aimed at enhancing rotation, steering response and mid-corner stability. With an all-new carbon chassis and refined suspension and steering components, this iteration focuses on controlled flex, improved durability and easier tuning.

Chassis

• Redesigned carbon chassis with mid and rear cut-outs to generate flex that increases rotation and steering.
• Approximately 12 g lighter thanks to the cut-outs, allowing more ballast to be positioned on the chassis for tailored weight distribution.

Upper Clamps & Arms

• New carbon rear upper holder improves durability in hard impacts. A wave-design plate replaces the previous cross member to allow greater rear suspension flex for better rotation and off-power steering.
• Link-style upper suspension arms included as an alternative to CFF upper arms, offering maximum adjustability and improved handling in specific conditions.

Shock Absorbers

• Shorter shocks, mounted 3 mm lower than the previous geometry, increase cornering speed, mid-corner steering and stability while helping reduce traction rolling in high-traction conditions.
• Updated shock holders reposition the upper mounts to complement the shorter shock geometry.

Steering System

• Redesigned servo mount to suit the new carbon battery holder.
• Adjustable steering arm with eccentric bushings for quick Ackermann tuning.

Additional 2026 Updates

• Reworked rear top deck with a more open rear section to boost rotation and off-power steering.
• Carbon battery holders for a cleaner, more modern look.
• All-new wave-design carbon body post holder enabling additional rear suspension flex for enhanced rotation and off-power steering.

Together, these updates make the XRay X4F 26 a precise and tunable platform, with carefully engineered flex characteristics and convenient adjustability built into key areas.
