I run Elka stage 1 custom valved and sprung for my rhinos weight and they ride like a dream and are no comparison to stock shocks in ride or handling. I have 325lbs front spring and 550lb rear springs. I often wished I had gone stage4 but guy from elka told me and my dealer I wouldnt notice a difference in ride on a trail comparing the two to justify the difference in price so that alone sold me that the company wasnt trying to over sell me. Said a custom sprung and valved shock would ride as well as a piggyback except in 30 minutes of whoops at the dunes. Madmax1 is running same elka shocks I am he had his setup after me and seems to love his and they were only $975 for set of 4.
