I just installed a Jeep air kit a few weeks ago. Everything fit pretty well other than the aftermarket AC lines they use were WAY OFF. They were nowhere near fitting as they came but eventually I got them to fit. It's nice that they supply all the little stuff you need like the recirculation door and actuator, AC compressor brackets, receiver/ dryer bracket, etc. I just wish they supplied better lines with their kit. I ended up having to replace all the o-rings after tweaking the lines countless time to get them close to where they should be.
