GPD 6511565 New A/C Compressor HD SD508 Style 7-Groove Serpentine 12V

The GPD 6511565 is a new heavy-duty A/C compressor built to the SD508 / SD5H14 specification, featuring a 7-groove serpentine clutch pulley and 12-volt electromagnetic clutch coil. Designed as a direct-fit replacement for original equipment compressors across a wide range of commercial trucks and heavy-duty applications, this unit is manufactured from all-new components — never rebuilt or remanufactured.

The SD508 platform is one of the most widely adopted compressor designs in the aftermarket, valued for its compact, lightweight construction and efficient piston-driven operation. The design robs less horsepower from the engine compared to many OE units, contributing to improved fuel economy without sacrificing cooling performance.
