Applications
This Type 30/30 long-stroke tandem chamber fits drive and trailer axles equipped with the 3030-TSLS pattern across:
- Class 8 tractors (Freightliner, Kenworth, Peterbilt, Mack, Volvo, International, Western Star)
- Heavy-duty trailers and tankers using long-stroke service brakes
- Vocational and refuse chassis with combined spring brake / service chamber requirements
Confirm chamber type (Type 30/30, long stroke), mounting bolt centerline, push-rod length, and air-port orientation before ordering. Long stroke chambers must be matched to long-stroke-rated slack adjusters and pedal valves.
