Yep all complimentary! With lift springs instead of the stock springs with spring spacers, you get the same ride height increase that the stiffer spring provides but with less preload at top out. The spring spacer could actually be stacked on top of the spring for additional lift if someone were to want to do that.Cool ... thanks. So the rear Index components are complimentary with / can be used with taller springs and achieve their intended purpose (factory 35 shock travel)? Same benefits as using with OE (springs)? If so, I’m in.
