Cognito 1-Inch Elite Ball Joint Leveling Kit with Fox 2.

AT4/AT4X/Trail Boss/ZR2 are popular with the interior upgrades, paint matched bumpers and door handles (or the upgraded black bumpers AT4X/ZR2), and black trim instead of chrome. They also have an increased ride height over the other models, essentially a leveling kit with also a lift block added in the rear. The AT4 and Trail Boss still have cheap shocks and a hefty nose down rake.

The AT4X and ZR2 have upgraded shocks (Multimatic Dssv) which are better but still leaving a lot of performance and ride quality on the table.

Adding this Cognito leveling kit will maximize the suspension travel opportunity by adding 1 more inch of front droop travel and then converting that into 1 more inch of front ride height. Maintaining a minimum of 3 Inch of droop travel is crucial for optimum ride quality, and adding the 2. 5 Inch Fox Performance Elite Series Reservoir shocks is another major upgrade in dampening control.
