The legendary quality of Global compressors has been built into this GM style compressor that fits many GM trucks from approx 1996 up. At almost $200 less than the Delco jobber price for the HT6 this is a fantastic deal. Now the DIY people and the shop customers can save a little money for themselves or their customers and put a little more money back in their own pockets! Get 'em while they're hot.  2 piece case eliminates the center case leakage so prevalent in the original HT6 compressors.
