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

Zone Offroad 6-Inch Front / 3-Inch Rear Lift Kit | Nitro Shocks | 2017–2019 Ford F-250 / F-350 4WD Gas 3-Leaf Main Spring Pack | SKU: F113N

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 at the lowest price point in the Zone Offroad 2017–2019 Super Duty Gas lineup. 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). 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 F112N or F112F instead. If you want Fox Adventure Series shocks instead of Nitro, order F113F.

The Result

The Zone Offroad F113N 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. Nitro gas shocks are included front and rear, valved for the lifted Super Duty geometry.
