About the XB4 2025 Buggy
Innovative Updates & Improvements
The XRAY XB4’25 Carpet (XB4C) and Dirt (XB4D) Editions are meticulously engineered to redefine 1/10 electric 4WD competition buggies. For the Carpet Edition, enhancements like the multi-adjustable slipper one-way clutch and aluminum central bulkhead elevate performance on high-traction surfaces. Conversely, the Dirt Edition employs a central gear differential and composite central bulkhead to maximize traction and consistency on low-traction tracks. Both models feature improved anti-roll bar geometry with super easy adjustment from the top, offering seamless adaptability. Graphite suspension components and innovative steering designs ensure precise handling, while updated shock towers and body configurations lower the center of gravity (CG) for enhanced cornering stability and speed. These forward-thinking upgrades make the XB4’25 an exceptional choice for racers seeking competitive excellence tailored to specific track conditions.
Chassis
The XRAY XB4C and XB4D chassis layouts showcase advanced flexibility for optimal performance across different terrains. The Carpet Edition's carbon chassis T-brace and slipper carbon center upper deck offer rigidity and durability, essential for the high-speed precision required on high-traction tracks. Meanwhile, the Dirt Edition employs a carbon chassis brace and differential carbon center upper deck, providing balanced flex characteristics to maximize grip on looser surfaces. Both kits feature adjustable rear transmission positions, enabling racers to switch between short and standard wheelbase setups for ultimate control. The Gamma 4C lightweight body on the Carpet Edition enhances stability through high-speed corners, while the Gamma 4D body of the Dirt Edition optimizes rear-end traction for tighter, technical layouts.
Suspension
The suspension system on the XB4’25 has been reimagined to deliver unparalleled adaptability and control for both editions. The Carpet Edition boasts graphite suspension arms and rear lower shock adapters that enhance handling in high-traction environments. Paired with aluminum steering plates, these components ensure precise response and stability during aggressive cornering. For the Dirt Edition, hard suspension arms and a graphite steering plate provide the flexibility and durability needed to maintain traction on rougher surfaces. Both models feature wider A, B, C, and D suspension holders, creating a more stable geometry that enhances drivability and on-power stability. Updated caster blocks, rear uprights, and shock mounting adapters further refine the handling characteristics, enabling racers to fine-tune their setups for optimal performance.
Drivetrain
The drivetrain configurations of the XB4C and XB4D are tailored to meet the demands of their respective environments. The Carpet Edition integrates a front central dogbone drive shaft and a longer 117mm rear central dogbone, supporting the long-wheelbase setup required for high-speed stability. The Dirt Edition, in contrast, employs a shorter 113mm rear central dogbone to facilitate a short-wheelbase configuration, boosting maneuverability and rear traction on loose tracks. Both editions benefit from updated 84mm front drive shafts, which complement the wider suspension geometry for enhanced durability and power delivery. Steel differential gears ensure maximum reliability, while the aluminum or composite bulkheads reduce weight and improve flex characteristics. Together, these innovations establish the XB4C and XB4D as the pinnacle of efficient, race-ready drivetrain systems.
