Description and Purpose

Parts Finder Q provides the ATR-6 Traction Relay Valve, engineered to control brake pressure for enhanced stability and safety. This essential component improves air brake and traction control functionality, 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 and more reliable vehicle operation.

Why Replacement is Important

Replacing a faulty ATR-6 Traction Relay Valve is vital for maintaining braking performance, stability, and safety. A worn valve can cause uneven braking, extended stopping distances, and reduced traction, leading to potential safety hazards and higher maintenance costs.
