LS aftermarket air with rear air

[Jens Jimmy]

Hey guys, has anyone had any experience with going aftermarket air on an LS swap and maintaining the rear air in a 72?
Totally new adventure, Hoping for some advice.

No, but I would expect the packaged Sanden compressor for a truck system would not have enough displacement. Sanden does make larger displacement compressors that would probably do the job.

The GM R4 compressor is about 164cc for comparison.

Re-read your post. Are you going to use the factory Denso compressor? I think they are 177 cc so that will work fine. You'll just have to find the proper t's and tie into the lines.

It shouldn't be a problem, you will just need the correct parts.

Hey Guys, Thanks for the response. I have the stock compressor on the 6.0 , I would like to use it if it will work.
If someone makes the correct fittings to adapt it, that would be awesome.
A/C has always been a thorn in my side, never quite understood it.

I was thinking of doing the same. My rear air worked ok up until my compressor died. My mechanic is suggesting a Vintage Air GenIV (Sanden) compressor replacement (not the complete system upgrade).

I'd love to hear your experience on this one...probably a couple months before I do it myself.

Me too, I'm in early stages. Im working on suspension now. Motor is done, trans is done, wiring harness is done. Finish brakes and suspension, then minor body work, a/c and paint.
