Trailer ABS Valve and Electronic Control Unit Assembly – 4S/3M

The WABCO 4005001030 is a genuine TCS II Premium Trailer ABS Electronic Control Unit (ECU) and Valve Assembly (4S/3M configuration) of premium original quality. It is engineered to control and regulate trailer anti-lock braking systems and traction control systems, ensuring superior safety, stability, and braking performance for heavy-duty commercial trailers.

This Trailer ABS Valve Kit is a service component used to restore consistent valving behavior in air systems that depend on clean airflow distribution. Its internal layout helps stabilize circuit transitions in braking and suspension functions where air is constantly cycling between chambers. The kit’s fitment profile aligns with standard heavy-duty valve housings, helping reduce troubleshooting time during scheduled repairs or diagnostic work. Its construction method supports longevity in environments exposed to temperature swings, vibration, and repeated air-system cycling. This valve 4005001030 is frequently installed during full air-system refreshes that prioritize steady circuit performance.
