2011-2016 F250 & F350 4WD Zone Offroad 4" Radius Arm Lift Kit (Diesel) F25

Gives Your F250 or F350 a Boost in Ride Height for a Tough Look

A big, powerful 6.7L Super Duty looks at its absolute best when riding high on in the air on big wheel and tire combinations, and one of the best ways to make that happen is with a 4" suspension lift kit from our friends over at Zone Off-Road. This complete front and rear suspension lift kit comes with a pair of heavy-duty radius arms and everything else you need to get your mighty F250 or F350 diesel truck riding higher while getting the extra wheel well clearance to fit on 35x12.50" tires for some extra ground clearance and improved off-roading potential. Zone's 4" Super Dut Lift Kit offers up an excellent balance of quality, durability, fitment, and price which makes it perfect for Super Duty trucks that do a little bit of everything. The kit uses a pair of lifted springs to add up to 4" of front lift and a 5" rear block that replaces your truck's stock block for 3" of lift to give your truck a nice boost in hide height with reduced rake over stock.

Strong Lifted Springs with Extremely Heavy-Duty Radius Arms

The kit's front springs are much taller than stock and were carefully designed by Zone to provide excellent street ride quality while still being able to handle tough, off-road challenges without letting you or your truck down. The front suspension is further tied together by Zone's radius arms which are each made from 1/4" thick steel plates and feature a strong, boxed design that perfectly locate your Super Duty's front axle in just about any condition or application. The radius arms come standard with greasable polyurethane bushings for reduced deflection without a huge increase in NVH. The front end of this lift kit is rounded off by a new track bar and your choice of either Zone's white-body Hydro Shocks or their performance Nitro Shocks with your choice of boot color.

Larger Rear Block with High-Quality U-Bolts, Washers, and Nuts

The rear of this kit is lifted by a completely new 5" block that replaces your truck's stock block so that you don't end up stacking blocks and getting a weird look and poor ride quality. The blocks are each held in place by zinc plated U-bolts and hardened nuts and washers that keep the blocks locked into place even in the most extreme driving or in heavily modified and tuned trucks. The rear end is rounded out by your choice of either Zone's standard white-body Hydro shocks or their performance Nitro shocks with a choice of boot to give your truck the ride quality or off-road performance that it needs.

Wheel and tire fitment: this kit will fit with 17" or larger wheels with at least 4.5" of backspace and can fit up to 35x12.50" tires.

Driveshaft Fitment: Super Dutys with a two-piece driveshaft may require one of Zone's carrier bearing drop brackets. Please select your carrier bearing option from the drop-down menu above.
