ReadyLift leveling kit.
ReadyLIFT customers have asked for it and we have delivered. The AT4/Trail Boss are factory equipped with a 2" front lift. This front lift includes a longer front shock/strut assembly. The ReadyLIFT 66-3921 1.75" leveling kit is similar to our popular 66-3086 leveling kit for pre-2019 trucks. The 66-3921 leveling kit provides required amount of lift without causing conflict with the factory strut geometry and clearances. Note: AT4 and Trail Boss do not fit the same size tire. This is due to the difference in front fender opening design.
A leveling kit raises the front to match the factory rear height, without changing the rear suspension.
