Gunite 5.5" Automatic Slack Adjuster
The Gunite 5.5" Automatic Slack Adjuster maintains a consistent brake-stroke relationship through its cam/spline configuration, allowing braking systems to retain predictable pedal response across demanding routes. Its 1.5" cam and 28-spline pairing gives brake hardware a tight mechanical link, supporting steady system balance during long service cycles. The adjuster’s compact arm profile simplifies fitment into crowded brake assemblies, lessening the time spent maneuvering around chambers or mounting hardware. The Gunite AS1140 also integrates reliably with fleets that refresh brake components on rotating intervals, reducing inconsistencies between wheel positions.
