Schumacher CAT PB-D 1/10 4WD Off-Road Buggy Kit (Dirt Spec)

About the CAT PB-D Off-Road Buggy Kit

Dirt Spec Drivetrain Performance

The CAT PB-D Dirt Spec is equipped with a shaft-driven 4WD system that delivers explosive acceleration, superior efficiency, and outstanding reliability. Designed for lower-grip tracks, this version features a three-differential layout to distribute power more efficiently across all four wheels. It comes with CVD rear driveshafts and universal joint fronts for a balance of strength and flexibility, while fast-access transmission housings, an updated spur gear, and adjustable differential height ensure racers can adapt quickly to changing dirt and outdoor conditions.

Refined Suspension & Handling

Engineered for razor-sharp handling, the CAT PB-D includes long front wishbones, updated rear suspension arms, and versatile suspension pills for limitless adjustment. Adjustable camber plates, roll centers, toe, and anti-squat allow racers to fine-tune handling for every track. Additionally, strong S2 shock towers, pre-drilled pistons, and improved anti-roll bar fitment provide both durability and precision. With its low center of gravity design, the buggy remains stable, agile, and predictable under pressure.

Durable Chassis & Aerodynamics

The heart of the CAT PB-D is a narrow, hard-anodized 7075-T6 aluminum chassis reinforced with composite side pods and carbon fiber top braces for tunable stiffness. A lightweight front bumper, angled servo mount, and carbon fiber speed control tray keep weight low and centered for optimal balance. Topped with a JConcepts S2 body and Aerox Trident wing, the buggy delivers downforce, clearance, and responsiveness for high-speed racing. This combination ensures the CAT PB-D is built to last and built to win.
