IMPORTANT NOTES: 

1. Ford recommends the replacement of the pitman arm nut after each time it has been removed.
2. If installed on a truck with a top-mounted overload spring, an overload spacer block taller than 1-1/8" UBT4027 (Qty: 4) is required.
3. Use a small pitman arm puller to remove the drag link joint and steering stabilizer taper.
4. If your truck is equipped with a 2-piece rear driveshaft, a Carrier Bearing Drop Kit may be required: BDS123402.
5. 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.
6. Larger tires on the stock wheels are not recommended due to the brake line clearance required. Use recommended specs listed in the wheel and tire fitment section.
7. Minor trimming may be necessary for clearance of 37x12.50 tires on certain wheel setups.
8. Installation requires a torque wrench capable of 405 ft-lbs.
9. 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.
