Important Notes
- Designed for use on diesel models, but can be installed on gas model trucks (will achieve an additional 1/2" front ride height).
- Larger tires on stock wheels are not recommended due to the brake line clearance required. Use recommended specifications listed in the tire and wheel fitment section.
- Installation requires a torque wrench capable of 405 ft-lbs.
- Due to the taller factory ride height, Tremor models will not net the full advertised lift height. The final ride height will be the same as standard models.
- Some trucks with a rear driveline vibration may have a recall from Ford regarding the rear axle. (Safety Recall 21S31) Due to the recall procedure, BDS recommends having this performed prior to installing the lift.
- Trucks without top-mounted overload springs require (x4) UBT4031 available to purchase separately.
