High Clearance Crossmemebers

BDS maximizes ground clearance with their heavy duty 1/4-inch thick laser cut perfect fit crossmembers. Paired with a front skid plate system that bolts together to create a rigid subframe while adding extra protection.

Heavy Duty Steering Knuckles

BDS corrects steering geometry at the new taller ride height using a pair of high-strength, CNC machined ductile cast iron steering knuckle design to work with replacement tie rod ends to maintain steering angles for proper function and ESC compatibility.

Important Notes

1. 18" or larger diameter wheels are required. Stock 17" and 18" wheels cannot be re-installed. Stock 20" wheels can be used with up to a 305/60R20 tire.
2. 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.
3. Models with 2-piece rear driveshaft WILL require carrier bearing shim kit 122406 (not included w/ kit)
4. Block kits replace factory 1-1/4" block. The stock block will not be reinstalled.
5. Crash bars may require modification based on wheel and tire choice. It is the end user's responsibility to ensure modifications are non-detrimental to vehicle safety.
6. Does NOT fit diesel models.
7. Will not work with Tremor models.
8. 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 having this performed prior to installing the lift.
9. This system has not been tested on models equipped with Ford BlueCruise.
10. Will not work with models with CCD (Continuous Controlled Damping)
