Description and Purpose

Parts Finder Q provides the ATR-6 Traction Relay Valve, designed to regulate brake pressure for improved stability and safety. This essential component enhances air brake and traction control performance, optimizing braking efficiency and handling in International/Navistar® and Ford F-650/F-750 trucks.

Impact on Vehicle Performance

The ATR-6 Traction Relay Valve enhances braking stability by regulating air pressure, preventing wheel lockup, and improving traction. It ensures smoother braking, reduces component wear, and optimizes ABS and traction control for safer, more efficient vehicle performance.

Why Replacement is Important

Replacing a faulty ATR-6 Traction Relay Valve is crucial for maintaining braking efficiency, stability, and safety. A worn valve can cause uneven braking, longer stopping distances, and reduced traction, increasing safety risks and maintenance costs.
