Description and Purpose

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

Impact on Vehicle Performance

The ATR-6 Traction Relay Valve improves braking stability by managing air pressure, which helps prevent wheel lockup and boost traction. It delivers smoother braking, minimizes wear on components, and fine-tunes ABS and traction control for a safer and more dependable vehicle performance.
