    FAQ

    Can I reuse my OBS truck's A/C compressor?

    Yes. The kit is designed to reuse the factory R4 compressor used on 1988 to 1995 GM trucks.

    Which alternator, water pump, and crank pulley are required?

    It requires the 1999 to 2013 GM truck DR44 alternator, the 1999 to 2013 truck water pump, and the 1999 to 2013 truck crank pulley.

    Are the tensioner and belt included?

    No. CVF specifies a Gates 38163 tensioner and Gates K061037 belt, sold separately.
