If the existing self-adjusting slack adjuster exhibits looseness in the arm or spline fitting, stripped or worn splines, cracks, corrosion, or visible physical damage, it’s time to replace it. That’s why we have introduced the Automatic Air Brake Slack Adjuster. It automatically maintains the correct clearance or slack between the brake shoes and the brake drum. It adjusts the slack itself over time, eliminating the need for manual adjustment. This crucial mechanical component will further reduce manual maintenance. Explore more about this aftermarket product with the compatibility list below:-

• Safe & Reliable Braking: The automatic slack adjuster will ensure proper brake clearance (slack) and force transfer within the air brake system. It connects the brake chamber push rod to the S-cam shaft, converting the linear motion into rotational force. It ensures effective and controlled braking. You don’t need to make manual corrections. Additionally, we provide a vast array of brake parts for you to explore.
• Precision Arm Span: This self-adjusting slack adjuster is designed to fit S-cam shafts with a 1-1/2 inch diameter and 28 splines. It will ensure a secure and precise fit with an arm length of 5.5", allowing consistent braking across various axle configurations. The unhanded design with a drilled worm wheel will fit on either side (left & right), and you can seamlessly use it with welded clevis brake chambers.
• Long-Term Use: This replacement slack adjuster is made from durable metal (ductile nodular iron) that protects against corrosion. It works seamlessly in harsh environments, weather conditions, and on roads. The robust material will provide reliable performance under demanding loads and heavy braking. The high-strength ductile iron will protect against cracking under stress, while the pre-lubricated and sealed parts will ensure long-lasting performance.
• Compatibility List: This air brake manual slack adjuster is an aftermarket mechanical component that fits specified OEM (original equipment manufacturer) and brands. It features collor-lock straight clevis for security, and you don’t need external brackets for installation. Check the list thoroughly before getting one for yourself. Check the complete list below:
