Zone Offroad 5-Inch Lift Kit with Fox Adventure Series Shocks — Ford F-150 Tremor SKU: ZONF107F

This kit lifts the F-150 Tremor 5 inches up front and 3 inches in the rear using high-strength crossmembers, ductile iron steering knuckles, and top-mounted strut spacers paired with a rear block kit, all matched with Fox Adventure Series shocks and supporting hardware to correct geometry and level the stance.

Before ordering: This kit fits 2021–2026 Ford F-150 Tremor, 4WD, gas models only. It does not fit diesel models. Installation requires frame bracket modification. Trucks with a 2-piece rear driveshaft require carrier bearing shim kit D5405, sold separately. Confirm driveshaft configuration, wheel diameter (18" minimum), backspacing, and tire size before ordering.

Required separately: Carrier bearing shim kit D5405 (required for 2-piece rear driveshaft models). Professional installation is strongly recommended for this Difficult-rated, 8–10-hour installation. 18" or larger wheels required — stock 17" and 18" wheels cannot be reinstalled after this lift.

Verified Fitment

4 Auto note: Fits models with 4 Auto that do not have the 4WD actuator hub assembly.

Ford Recall 21S25: Zone Offroad recommends completing Ford Safety Recall 21S25 (rear driveshaft) prior to installing this kit on affected 2021 trucks.

Critical Compatibility

• Diesel exclusion: Does not fit diesel models. Gas models only across all years.
• Frame bracket modification required: Installation requires modification of the frame bracket. This is not optional.
• 2-piece rear driveshaft: Models with a 2-piece rear driveshaft require carrier bearing shim kit D5405 (not included, sold separately). Verify your driveshaft configuration before ordering.
• Ford Recall 21S25: If your 2021 F-150 Tremor is subject to Ford Safety Recall 21S25 (rear driveshaft), Zone Offroad recommends completing that recall procedure before installing this kit.
• Wheel diameter: 18" or larger diameter wheels are required. Stock 17" and 18" wheels cannot be reinstalled after this lift. Stock 20" wheels can be used with a tire no larger than 305/60R20.
• Wheel backspacing — 18" wheels: 18" wheels with 5–5.5" backspacing should be test-fit on the vehicle prior to mounting the tire to confirm clearance to the steering knuckle and tie rod. 18–20" wheels with 5.5–5.75" backspacing are highly recommended for clearance between the tire and frame crash bar.
• 37" tires: Require crash bar modification. Crash bar modifications are the end user's responsibility; ensure all modifications are non-detrimental to vehicle safety.
• 4WD actuator hub: Fits models with 4 Auto that do not have the 4WD actuator hub assembly.
• Rear block: Block kit replaces the factory 1-1/4" block. The stock block will not be reinstalled.

Installation Notes

Professional installation is strongly recommended for this kit, which is rated Difficult with an estimated 8–10-hour install time. A professional alignment must be completed after installation.

Required tools: 204-592 Ball Joint Separator (recommended), torque wrench, reciprocating saw, strut compressor.

Before beginning installation: Confirm driveshaft configuration. If the truck has a 2-piece rear driveshaft, carrier bearing shim kit D5405 must be on hand before installation begins. If the truck is subject to Ford Recall 21S25, complete that recall procedure first.

Frame modification: This installation requires frame bracket modification. Follow the Zone Offroad installation instructions for the approved procedure.

Refer to the current Zone Offroad installation instructions supplied with this kit for complete procedures, torque specifications, and all safety requirements.

The Obsidian Take

The ZONF107F gives the 2021–2026 F-150 Tremor a 5-inch front and 3-inch rear lift using ductile iron steering knuckles and high-strength crossmembers to correct geometry and maintain ESC compatibility — not just spacers stacked on OE geometry. Fox Adventure Series shocks are included. Four conditions to confirm before ordering: gas models only (no diesel); installation requires frame bracket modification; 2-piece rear driveshaft trucks need carrier bearing shim kit D5405 (not included); and stock 17" and stock 18" wheels cannot go back on after this lift. For 37" tires, crash bar modification is required and is the owner's responsibility.

• You are prepared for a Difficult-rated, 8–10-hour installation requiring a reciprocating saw, strut compressor, and frame bracket modification.
• You have confirmed your driveshaft configuration and sourced D5405 if your truck has a 2-piece rear driveshaft.
