Slack Adjuster Cross Reference Chart

The JIT Truck Parts Slack Adjuster Cross Reference Chart shares slack adjusters compatible with a wide variety of semi-truck and heavy-duty commercial vehicle models and applications.
The part number, spline diameter, spline count, arm length, manufacturer and slack adjuster crosses are all listed below. The spline diameter and arm length are two important measurements to consider when choosing a slack adjuster, as they will determine whether the part will properly fit your vehicle.

In addition to the spline diameter and arm length, some other information that may be helpful when choosing a slack adjuster includes the following:

  • Bolt pattern: The bolt pattern refers to the number of bolts and their spacing on the adjuster.

  • Nut size: The nut size is the size of the fastener that secures the adjuster to the axle.

  • Torque specifications: The torque specifications are the values that indicate how much force should be applied when tightening the adjuster.

  • Lubrication: Some slack adjusters require lubrication to function properly. It is important to follow the manufacturer's recommendations for lubrication to ensure the adjuster performs as intended.

By leveraging the JIT Truck Parts Slack Adjuster Cross Reference Chart you can confidently select the slack adjuster best suited for your vehicle model and application, as well as shop prices.
