Finding the ideal shock length after a suspension lift is installed often ends with a choice that proves to be close but not perfect. Until you truly cycle your suspension in real world conditions, it is nearly impossible to know your exact compression and extension lengths. Forklifts and ramps help but are used typically for lifting one corner at a time. Shock choices are also somewhat limited to a select choice of lengths and those available may not be ideal for your frame and axle mounts. The repeated adjustability offered by the Currie brackets creates an avenue to get your shocks to be a perfect match to your suspension travel.
