Let me chime in here....save a little longer to get the "right" system. Otherwise, you are going to spend money trying to fix the other system. The old adage of do it right the first time. Sure it depends on what you want to do with the rig, but if you are rolling 37"s buy the right set up. Take a good long look at the Poly Performance stuff. If you have to, start with the stage 2 and go from there. You can build it as you need it. For example, I have the stage 3 and will be switching to the Poly long arm (eventhough I dont think it needs it as it flexes great, but you gotta have the new stuff). The current set up will allow me to keep certain components. Not to mention, I can not say it enough, RESEARCH THE COMPANY AND GET INPUT ABOUT THE CUSTOMER SERVICE. You are going to have questions and want good service, again, Poly is top notch here. A lot of guys are going to chime in a say this or that as they are biased to thier system. I have had expiernece with three major suspension companies and cant say enough good things about poly performance. The only bad thing about them is they keep making awesome stuff that I just seem to need!
