i have the chevies just like many others do and they work great. there cheap and not a hard swap. sometimes i wish i would have went with a rear lift spring from marlin as i continue to build my truck more. why, because with the chevies there really long and your rear shackle hangs out a lot more. with a bed bob it kinda makes them stick out even more. its no big deal though, many people work around it. i would just like my shackles tucked under my truck more. either way is a good choice in my opinion. you cant go wrong with either.
