Important Notes

• 18" or larger diameter wheels required. Stock 17" and 18" wheels cannot be re-installed. 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. 5.5" backspacing is highly recommended for tire to frame crash bar clearance.
• Models with 2-piece rear driveshaft WILL require carrier bearing shim kit 122406 (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.
• Will fit models with Auto 4wd that do NOT have the 4WD actuator hub assembly.
• Does NOT fit diesel models.
• Tremor models: only the 3-1/4" rear block is recommended. Larger blocks cause driveline vibration. Expected rake is 1" with new block installed. Factory block provides slight tail low stance if desired
• Some trucks with a 2 piece drive shaft may have a recall from Ford regarding the rear driveshaft. (Safety Recall 21S25) Due to the recall procedure, BDS recommends to have this performed prior to installing the lift.
• This system has not been tested on models equipped with Ford BlueCruise.
• Will not work with models with CCD (Continuous Controlled Damping)
• Requires frame bracket modification.
