Important fitment 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. 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.
8. Will not work with models with CCD (Continuous Controlled Damping)
9. Requires frame bracket modification.
10. Recalibration of your vehicles Advanced Driver Assistance System (ADAS) cameras, radars, light detection and ranging (LiDAR), and other sensors may be necessary by your local dealership or ADAS service center. This will ensure proper functionality of the vehicle features such as lane keeping, lane departure, parking assistance, blind-spot detection, adaptive cruise control systems, and other functions as they did prior to installation. Please connect with your local dealership or ADAS service center. Similar to a wheel alignment, all charges and expenses that may occur from dealership calibrations and adjustments are the sole responsibility of the vehicle owner.

BDS warranty coverage is for the original retail purchaser with proof of purchase. BDS hard parts and bushings have lifetime replacement coverage; finish and normal wear are excluded.

BDS NX2 and BDS/FOX Performance Series shocks have limited lifetime coverage excluding normal wear and oil seals. At BDS’s discretion, qualifying leaking seals less than two years old may be considered for repair or replacement.

FOX proprietary shocks and coilovers follow FOX warranty terms rather than the BDS warranty. Qualifying leaking seals less than one year old may be considered; other FOX concerns follow the FOX service process.

Properly maintained ball joints and tie-rod ends less than three years old may qualify, subject to the manufacturer’s conditions.

Remedies are repair or replacement at BDS’s discretion. Eligible warranty ground shipping is covered; removal, installation, expedited freight and consequential costs are excluded.
