This is a Haldex automatic slack adjuster, a critical component in heavy-duty air brake systems.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It automatically maintains the correct clearance between the brake shoes and drum to ensure consistent, even braking performance. Automatic slack adjusters replace manual versions and are required by regulations to compensate for brake lining wear without driver intervention. A worn or seized slack adjuster can cause brake imbalance, so they are replaced when the internal mechanism fails or the splines wear out.
