Here's a Kwik and easy solution to your LSx engine swap AC compressor problems
Here's how to solve those problems:
- You may have clearance issues with the frame or crossmember. That's especially true for
chassis such as S-10s, early Camaros and Chevelles, and many full size Chevy pickups.
- You may be concerned about the LSx "variable displacement" compressor being
compatible with your earlier factory AC system or with an aftermarket system.
- Use an aftermarket compressor like the popular Sanden.
- Mount it with a bracket kit from Kwik Performance, Inc., available in three different versions:
Corvette; 98-02 Camaro & Firebird/GTO; and truck/2010-11 Camaro.
