Important notes before you order
- Some trucks with a 2 piece drive shaft may have a recall from Ford regarding the rear drive shaft. (Safety Recall 21S25) Due to the recall procedure, Zone Offroad recommends to have this performed prior to installing the lift.
- 18" or larger diameter wheels required. Stock 17" and 18" wheels cannot be reinstalled. 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. 18 - 20"wheels with 5.5-5.75" of backspacing is highly recommended for tire to frame crash bar clearance. 37" tires will require crash bar modification
- Models with 2-piece rear driveshaft WILL require carrier bearing shim kit D5405 (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.
- Loaded Struts are recommended to use the 5” tall block for a level stance, 4” block will result in a tail low stance
- Will not work with trucks equipped with CCD (Continuous Controlled Damping)
- Does not fit diesel models.
- Will not fit Tremor models.
- Requires frame bracket modification
- 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.
TRU specialist notes
From the Trucks R Us fitment and install team, beyond the manufacturer's information.
- Plan for a professional wheel alignment after installing any lift or leveling kit.
- Going to bigger tires as well? Speedometer recalibration may be needed, and some tire and wheel combinations need trimming. Check the recommended wheels and tires, or ask us before you order.

Overview
Give your 2021-2026 Ford F-150 the height, clearance, and aggressive stance it deserves with the Zone Off Road 6-inch Lift Kit. Designed to improve capability on and off the trail, this system provides the clearance needed to run up to 37-inch tires while maintaining solid on-road handling. The lift is built around precision-engineered steering knuckles which properly correct suspension geometry at the taller ride height. To complete the system, the kit includes heavy-duty crossmembers, a differential drop, sway bar drop brackets, skid plate, rear lift blocks, and new U-bolts for a complete, properly engineered suspension upgrade which is proudly Made in the USA.
Up front, you can choose the setup that best fits your build. One option uses OE strut spacers, allowing you to retain the factory front struts while achieving the full lift height. This configuration can be paired with either Zone Nitro rear shocks or upgraded FOX 2.0 Adventure Series rear shocks for improved ride control. For a more complete front suspension upgrade, the kit is also available with Zone Nitro loaded struts, which arrive fully assembled and ready to bolt in, paired with matching Zone Nitro rear shocks for balanced performance and easy installation.
In the rear, Zone gives you the ability to fine-tune the stance of your truck. A 4-inch rear block levels the truck for a clean, aggressive look, while a 5-inch rear block retains some of the factory rake for those who prefer a slightly higher rear stance for hauling or towing.
Built with durability in mind and engineered for an easy installation, the Zone Off Road 6-inch Lift Kit is a straightforward way to transform the look and capability of your F-150 without sacrificing everyday drivability.
