any info links about the differences with other models like the 505 and the sanden sd7 --besides this being a serpentine,


the 508 is said to soak up 7hp and that's definitely who peeps here like it


Chrome Mini AC Compressor - Sanden SD-7 Style - Serpentine Pulley 6 GROOVE | eBay


im buying all the serpentine system to go on a ls engine, it takes a few days of homework to find the cheapest route, when you decide which of the three-witch is dictated by the harmonic balancer on the crank -the distance the three systems are spaced out from the front of the engine.


my choice is the

09-14 Cadillac CTS-V CTSV 2nd Gen Alternator Bracket W/ Pulley OEM 56247 | eBay
c5/ c6 vette/ cts-v parts.
