WABCO ABS System Package 4005000880 Anti-Lock Brake Valve Kit for Heavy Truck Trailer

The WABCO ABS System Package (part number 4005000880) is a complete anti-lock braking solution engineered for heavy-duty trucks, tractor units and semi-trailers. Built around genuine WABCO solenoid valve technology, the package delivers strong braking stability by preventing wheel lockup during emergency braking. On wet, icy or snow-covered roads it keeps the wheels rolling, avoids dangerous skidding and preserves steering control, which shortens the stopping distance and protects both the driver and the payload. Every component is produced to OEM specification, so the package installs directly into existing air brake circuits and performs reliably across the full service life of the vehicle.

At the heart of the package is a high-cycle solenoid control valve that regulates brake chamber pressure within milliseconds. It combines durable construction, waterproof electrical connectors and straightforward diagnostics, making it the practical choice for fleets that demand predictable maintenance and minimal downtime.

• Strong Braking Stability: The control unit continuously monitors wheel speed and modulates brake pressure within milliseconds, preventing wheel lockup under emergency braking and keeping the vehicle steerable on wet or snowy roads.
• OEM-Grade Reliability: Each solenoid valve is rated for more than two million actuation cycles with an extremely low failure rate, matching the durability of genuine original equipment parts.
• Lower Running Costs: By eliminating wheel lock and excessive tyre slip, the package reduces tyre wear and extends the service life of tyres and brake chambers, while lower air consumption saves roughly one percent of fuel.
• Waterproof Connectors: Sealed, waterproof electrical connectors resist moisture, road salt and high-pressure washing, maintaining stable signal transmission in harsh weather and heavy vibration.
• Expandable Safety Functions: The system can be upgraded with ASR traction control and RSC roll stability control, adding advanced safety features without replacing the core hardware.
• Simple Diagnostics and Maintenance: Standard diagnostic interfaces let technicians read and clear fault codes quickly, cutting troubleshooting time and overall maintenance cost.

The package is designed for heavy-duty trucks, tractor units and semi-trailers that operate in demanding conditions such as long-haul logistics, construction haulage, mining and refrigerated transport. It suits fleets that run on mixed surfaces, from dry highways to wet, icy and snow-covered roads, where dependable anti-lock braking and predictable steering are essential for safety.

Because the system supports optional ASR traction control and RSC roll stability control, it is equally suitable for operators who want to expand safety functions over time without replacing the braking hardware.

Every WABCO ABS system package is packed in a neutral export carton with custom foam protection so that valves, connectors and fittings arrive free of damage. OEM packing and private-label cartons are available on request, and each carton carries a clear product label with the part number for easy warehouse handling.
