What air brake chamber do I need for my truck?

Match the number stamped on the chamber you're removing — the type (e.g. Type 30), the stroke (long or short), and whether it's a single service chamber or a 30/30 spring brake. PartStop stocks universal-fit T30/30 long-stroke, short-stroke, and double-diaphragm chambers as premium-quality aftermarket direct replacements. If the tag is unreadable, use the free VIN lookup at /vin or call (253) 600-1351.
