you are using the Stock compressor for the 5.7? Also what are you using as far as drive shafts go? Do you have a 10 bolt in the back, are you using the 4l80e? were you going to try and pull one out of a CC NBS? or have one custom made?
Hello, yeah man I am running the stock 95 R4 compressor, as for the driveshaft my truck was originally an 1/2 ton ext. cab 2wd automatic with a 4L60E, if you have that setup all you have to do when you lengthen the frame for the crew cab is swap your original rear half of your driveshaft, starting right behind the carrier bearing, for a RCSB with automatic driveshaft. It fit's perfect with no mod's. I have a built 4L60E with a Corvette servo, etc. that I am running behind the 6.0, if I have to change the only trans I will use will be the newer 6L80E. Lastly yeah i am running a 10 bolt with 3.42's, I have always liked those gears, for me they are a combination gear, good take off, but still low rpm's on the highway. I have another crew cab with a 14 bolt FF G80 and 4.10's I hate it on the highway. Another company that makes compressor brackets now is Novak, their website is novak-adapt.com and they make some nice stuff. Take it easy and if you have any other questions please ask.
