XBility RC XB-SF Simple Front 1/28 Electric Performance RWD On-Road Roller (Without Servo)

Innovative 1/28 Performance On-Road Racing Chassis

Built for drivers who demand precision, the XBility RC XB-SF combines lightweight carbon fiber construction, optimized weight distribution, and highly adjustable suspension geometry for sharp, predictable handling. From chassis flex to drivetrain efficiency, every detail is designed to deliver responsive performance and confident cornering.

About the XB-SF

Balanced Chassis Performance

The XB-SF combines a lightweight carbon fiber chassis with strategically positioned brass components to optimize chassis flex, weight distribution, and center of gravity. This carefully balanced setup helps maximize traction and delivers predictable handling through corners. The result is a responsive chassis that stays composed while pushing hard on the track.

Precision Front Adjustment

The Simple Front suspension system uses stainless steel shims to fine-tune front ride height without changing camber, caster, or suspension geometry. Interchangeable king pins and carbon caster plates provide precise control over camber and caster settings for dialing in front-end response. This gives racers the flexibility to quickly adapt the chassis to different driving conditions.

Responsive Corner Rotation

A redesigned damper plate with updated side spring geometry allows the chassis to rotate smoothly while maintaining stability and rear traction. The floating servo mount preserves natural chassis flex, while the simplified center pivot assembly provides smooth and precise movement. Together, these refinements create a more controlled and predictable response during aggressive cornering.

Advanced Drivetrain Design

The Xbility 3-Point Ball Differential eliminates wheel play with a three-point mounting design that keeps the wheels perfectly centered for smooth, efficient power delivery. The V2 motor mount lowers the motor by 0.5mm, while the V2 brass left motor mount improves left-to-right weight distribution and overall chassis balance. These drivetrain upgrades deliver consistent performance while making the car easier to tune and maintain.
