Zone Offroad 6-Inch Lift Kit | AAL + Fox Adventure | F-250/F-350 4WD Gas 2-Leaf | 2017-2019

Zone Offroad 6-Inch Front / 4-Inch Rear Lift Kit | AAL + Fox Adventure Shocks | 2017–2019 Ford F-250 / F-350 4WD Gas 2-Leaf Main Spring Pack | SKU: F112F

Is This for You?

This kit is for the 2017–2019 Ford F-250 or F-350 4WD owner with a gas engine and a 2-leaf main spring pack who wants 6 inches of front lift and 4 inches of rear lift with Fox Adventure Series shocks included. Two independent fitment gates must be confirmed before ordering: engine type (gas only — not diesel) and rear spring pack configuration (2-leaf main only — not 4-leaf). If your Super Duty has a 6.7L Power Stroke diesel or any other diesel engine, this kit will not fit. If your rear spring pack has 4 leaves or a different configuration, this kit will not fit. If your truck is 2WD, this kit will not fit.

The Result

The Zone Offroad F112F delivers 6 inches of front lift and 4 inches of rear lift on the 2017–2019 Super Duty IFS platform with corrected caster, camber, and scrub radius geometry via heavy-duty crossmembers and steering knuckles. The rear lift uses an add-a-leaf (AAL) combined with a 4-inch block — the AAL increases spring rate and load capacity while reducing axle wrap risk under heavy acceleration or towing. Fox Adventure Series shocks are included front and rear, valved for the lifted Super Duty geometry.

Verified Fitment (OFAS Standard)

• 2017–2019 Ford F-250 4WD — Gas Engine — 2-Leaf Main Spring Pack ✓
• 2017–2019 Ford F-350 4WD SRW — Gas Engine — 2-Leaf Main Spring Pack ✓
• Does NOT fit: Diesel-equipped F-250/F-350 — 6.7L Power Stroke or any other diesel configuration
• Does NOT fit: F-250/F-350 with 4-leaf or other spring pack configurations — 2-leaf main only
• Does NOT fit: 2WD / RWD F-250 or F-350
• Does NOT fit: 2016 or earlier Ford Super Duty
• Does NOT fit: 2020 or newer Ford Super Duty — different generation platform
• Does NOT fit: Ford F-350 DRW (Dually) — confirm separately
• Does NOT fit: Ford F-150 — incompatible platform

Dual Fitment Gates — Both Must Be Confirmed

• Gate 1 — Engine: Gas engine only. Does NOT fit 6.7L Power Stroke diesel or any diesel configuration. Check your door jamb or window sticker for engine code.
• Gate 2 — Spring Pack: 2-leaf main spring pack only. Count your rear leaf springs before ordering. Does NOT fit 4-leaf or other configurations.
• Both gates must be confirmed before ordering. Ordering the wrong spring pack version will result in incorrect rear lift fitment.

Rear Lift — Add-A-Leaf + 4-Inch Block

• Add-a-leaf (AAL): Adds a leaf to the existing 2-leaf main spring pack — increases spring rate and load capacity, reduces axle wrap risk under heavy acceleration or towing
• 4-inch block: Achieves the 4-inch rear lift height
• Combined result: improved load handling, reduced axle wrap risk, and 4 inches of rear lift — more complete than a block-only solution
