It builds and maintains air pressure for the truck’s brake system, delivering 13.2 CFM at 1250 RPM. You replace it when the original compressor can’t keep up with demand—usually because of worn piston rings, leaking valves, or internal carbon buildup—preventing full brake pressure. The unit is flange-mounted, water-cooled, and uses a spline drive, with left-side inlet and rear outlet ports. Includes installation gaskets; a CoreFree version (3018543RX) is available if you are not returning a core.
