Some trucks with a 2 piece drive shaft may have a recall from Ford regarding the rear drive shaft. (Safety Recall 21S25) Due to the recall procedure, Zone Offroad recommends having this performed prior to installing the lift. 18" or larger diameter wheels required. Stock 17" and 18" wheels cannot be reinstalled. Stock 20" wheels can be used with up to a 305/60R20 tire. 18" wheels with 5-5.5" backspacing should be test fit prior to mounting the tire to ensure proper clearance to the steering knuckle/tie rod. 18 - 20"wheels with 5.5-5.75" of backspacing is highly recommended for tire-to-frame crash bar clearance. 37" tires will require crash bar modification. Models with 2-piece rear driveshaft WILL require carrier bearing shim kit D5405 (not included w/ kit). Block kits replace factory 1-1/4” block. Stock block will not be reinstalled. Crash bars may require modification based on wheel and tire choice. It is the end users responsibility to ensure modifications are non-detrimental to vehicle safety.
