Elite Off-Road Racing Buggy, With Championship Pedigree!

The XRAY XB4C and XB4D 2026 are built for racers who demand absolute control, precision, and adaptability, featuring a fully lowered and centered layout, purpose-built carpet and dirt configurations, and premium lightweight engineering designed to deliver winning performance on any track.

About the XB4 2026 Buggy

Lower CG Design

The XB4C and XB4D 2026 kits feature a completely reworked chassis layout that places the motor, battery, and central drivetrain significantly lower and closer to the centerline of the car. This centralized mass distribution reduces rotational inertia and lowers the center of gravity, allowing the buggy to change direction faster, carry more corner speed, and remain more stable under braking and acceleration. The updated chassis machining, revised motor bulkhead, and smaller spur gears work together to minimize chassis roll while improving consistency and control on high-grip carpet and loose dirt surfaces alike.

Purpose-Built Track Versions

Each version of the XB4 is engineered specifically for its intended racing surface to deliver maximum performance without compromise. The XB4C Carpet Edition is tuned for high-traction tracks with an aluminum steering plate, ECS driveshafts, wider anti-roll bars, and a slipper one-way system that provides aggressive yet controllable acceleration. The XB4D Dirt Edition focuses on mechanical grip and forgiveness, featuring a center gear differential, composite steering plate, CVD driveshafts, a wider rear wing, and the high-downforce Epsilon body to generate traction and stability on low-grip and bumpy tracks.

Advanced Chassis Tuning

XRAY equips the XB4 platform with extensive adjustability to adapt to virtually any track condition. Multiple transmission mounting positions allow racers to choose between standard and short wheelbase configurations, while differential height adjustment fine-tunes driveline angles for optimal efficiency and traction. Updated suspension holders, revised shock tower geometry, adjustable anti-roll bars, and multiple battery positions give drivers precise control over flex, weight balance, and handling characteristics, making the XB4C and XB4D exceptionally versatile race platforms.

Premium Engineering

Every major component of the XB4C and XB4D is designed to deliver maximum performance with minimal weight. Ultra-light titanium turnbuckles and shock mounts reduce unsprung mass while maintaining exceptional strength and durability, and lighter differential and slipper outdrives decrease rotating mass for faster acceleration and braking response. Carbon fiber shock towers, a narrowed rear chassis brace, and refined big bore shocks work together to improve suspension efficiency, landing control, and overall precision, ensuring consistent, race-ready performance straight out of the box.
