This bracket system is designed to replace the factory A.C. compressor with an aftermarket Sanden 508 compressor. A.C. compressor is driven off the factory inner four grooves of the LS truck harmonic balancer. Bracket kit includes: Steel mounting brackets, mounting hardware, automatic belt tensioner, Dayco four-rib drive belt and illustrated instructions for easy installation.
Note: Check bracket and balancer dimensions below to insure proper fitment. For the 1999-2013 Truck, the measurement from the front of the balancer to the machined surface of the balancer needs to be 3″ deep.
