Automatic Slack Adjusters
Automatic slack adjusters in the 1-1/2 inch, 28-spline pattern with a 5-1/2 inch arm — the size most road tractors run — plus manual units with 5, 6 and 7 inch arms. Interchanges we carry include R801073, R801075, AS1150 and 40020227, fitting Freightliner Cascadia and Volvo. Spline count and arm length are what make it the right part; the brand on the box is not.
