GPD 6512717 New A/C Compressor Sanden SD7H15 Style 8-Groove 140mm 12V Direct Mount

The GPD 6512717 is a new replacement A/C compressor built to Sanden SD7H15 specifications for heavy-duty truck and commercial vehicle applications. Engineered as a direct-fit replacement for OE compressor part number SKI4802S, this unit restores full air conditioning performance without the cost of a remanufactured core.

The SD7H15 platform features a 7-cylinder swash-plate design with a fixed displacement of approximately 155cc per revolution, delivering consistent refrigerant flow across a wide engine RPM range. This compressor is configured with a direct mount (pad mount) bracket design, an 8-groove serpentine clutch pulley at 140mm diameter, and 12-volt clutch engagement — making it a common fitment in Freightliner heavy-duty truck platforms.
