Automatic Slack Adjusters

Brakes need to be constantly adjusted over time. Wearing down of pads and different trucker braking styles can make for tougher and inconsistent stops over time. Automatic Slack Adjusters work to adjust your brakes - you guessed it - automatically. Required by law in most states, ASAs are a standard in braking systems. Luckily, we've got 'em in spades.

Whether you drive Autocar, Mack, International, Sterling, Peterbilt, Freightliner, Volvo or Kenworth trucks - we have an automatic slack adjuster that will work with your truck's braking system. Not only will you find the ASA that will fit the right specs, but we have the highest quality product selection from major manufacturers like Bendix, Meritor and Haldex.

Have your brake problems fixed automatically - Just In Time.
