The SB Dirt Master features a distinctive retro-modern body design that blends classic styling with contemporary aerodynamic technology. The clear kit body allows for custom painting and personalisation, and included graphics decals add a finishing touch. A rear wing is also included for increased traction and stability.

Experience superior traction and driving stability with the rear-mounted motor configuration. This design optimises weight distribution for improved grip and handling, while a motor guard protects the motor from impacts during jumps and rough landings.

The proven double wishbone suspension system provides exceptional handling and responsiveness. Turnbuckle rods allow for easy adjustment of suspension geometry, while oil-filled shocks with dial-adjustable spring tension ensure smooth damping and customisable ride height. The suspension is even compatible with competition-level springs for advanced tuning.

The resin main chassis offers moderate flex characteristics, enhancing grip and stability while providing ample space for easy installation and assembly of RC components.

The rear gear differential ensures smooth cornering and is designed for easy assembly and maintenance. For those seeking even greater performance, the ball differential from the Ultima series (UMW602B) can be installed as an upgrade.

The drivetrain features full ball bearings, minimising friction and maximising efficiency. This design reduces power loss and ensures smooth operation for optimal performance.

An adjustable slipper clutch is included as standard to protect the gears and enhance traction. This feature allows for controlled slippage under heavy loads, preventing damage and optimising power delivery. A gear cover can also be installed to protect the gears from dirt and debris.
