To properly level a truck and maintain the best ride possible, you must maintain a minimum of 3" of droop travel which Cognito does with its SM Series Upper Control Arm kit that has a corrected ball joint angle along with a high articulation joint. The Cognito control arm kit is a boxed sheet metal design, has maintenance free ball joints and pivot bushings, durable black powder coated finish, geometry to maximize performance, all pre-assembled and ready to bolt on. Along with the control arm kit, a proper length set of shocks is needed for that droop travel, and this package includes the no holds barred Fox Factory Race Series 3.0 Internal Bypass Shocks which have the recirculating reservoirs which help keep shock oil temperatures at bay, and they also feature Dual Speed Compression (DSC) adjusters. “But I don’t race my truck” you say, we understand but that is what these shocks are called because they have all of the Fox racing technology embedded in them, again these are for a large budget individual who just has to have the best you can buy. The rear end of the truck will need to come up at minimum 1” to accommodate the longer rear shocks, and the height can come up to 2” or somewhere in between if you prefer, via the adjustable height Deaver mini packs that are included. Since The AT4 and Trail Boss models are already 2” taller, the stock overload spring will come out, as well as the stock 2” block and the 2” axle perch spacer for the bump stop. That will all get replaced with the included mini packs for a more plush ride on the bigger bumps, and the new 1.5” bump stop spacers in order to protect the shocks from bottom out. Longer U-bolts are included and round out the contents of the Ultimate Leveling kit.
