Zone Offroad 6-Inch Lift Kit | Fox Adventure | F-250/F-350 4WD Gas 3-Leaf | 2017-2019

Zone Offroad 6-Inch Front / 3-Inch Rear Lift Kit | Fox Adventure Shocks | 2017–2019 Ford F-250 / F-350 4WD Gas 3-Leaf Main Spring Pack | SKU: F113F

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 3-leaf main spring pack who wants 6 inches of front lift and 3 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 (3-leaf main only — not 2-leaf, not 4-leaf). If your Super Duty has a 6.7L Power Stroke diesel, this kit will not fit. If your rear spring pack has 2 leaves, order F112F instead. If your truck is 2WD, this kit will not fit.

The Result

The Zone Offroad F113F delivers 6 inches of front lift and 3 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 3-leaf main spring pack provides sufficient load support at 3 inches of block height without requiring an add-a-leaf — the stiffer 3-leaf pack maintains adequate axle wrap resistance at this block height. Fox Adventure Series shocks are included front and rear, valved for the lifted Super Duty geometry.

• Both gates must be confirmed before ordering.

F113F vs. F112F — Spring Pack Selection

• F113F (this listing): 3-leaf main spring pack | 3-inch rear block only (no AAL) | 3" rear lift | Fox Adventure shocks
• F112F: 2-leaf main spring pack | AAL + 4-inch rear block | 4" rear lift | Fox Adventure shocks
• The 3-leaf pack is stiffer and provides sufficient load support at 3 inches of block height without an AAL. The 2-leaf pack requires an AAL for adequate load support at 4 inches of block height.
• Count your rear leaf springs before ordering — do not guess.
