I got the shocks from Jenny's and ordered the rear shocks, but he mistakenly sent the fronts which are shorter. But all sorted now, today he sent me the proper ones. Great customer service if you ask me, I highly recommend themif you put some preload, then the felony shocks can work
but using the longer spring, that should be fine as is..(atleast for my usage) maybe a bit of tuning depending on how you run your truck
