Getting it "low", with 'stock' rails. first speed bump. Up front, once you go down 5" (spindle + spring) the stock lower control arm mounts hit everything in town. Out back its rail and bed floor issues. I never really got the whole 'bolt-in C notch' craze. Look, once the axle travels 3/4" into the notche area, the top of the third member housing smacks the bed floor. Thats a bunch of effort and $$ for 3/4". You will need to raire the bed floor and rails to get serious. Look at Mike Hickmans Hotchkis prepped C10. It handles great, and it's on stock rails, yes it has a small C notch. That is about as low as you can go on a stock platform and make it work.
