Exception: The correct length shocks must be used. Shocks that are under proper length will over extend; shocks that exceed proper length will bottom out. Either of these conditions will cause damage to the shocks, shock hoops and upper control arms, and will not be covered by warranty. When this kit is installed using the factory mounting location, 19” is the maximum extended shock length requirement, and maximum compressed length is 12.5” (measured from center to center of mounting bolts). At ride height, a minimum of 3” of shock shaft should be showing. Exception: Part number 110-90195 (Old Sku: DSHK100002) Only. Due to shorter body mounts compared to HD models, modification/trimming is needed to provide clearance between the top of the dual shock hoop and the upper portion of the inner fender well.
