11-12 Ford F250/F350 - Zone Offroad 4" Radius Arm Lift Kit

The new Zone Offroad 2011-12 Ford Super Duty 4" radius arm suspension lift features tough replacment radius arms that are considerably stronger, made of 1/4" steel, fully boxed, and utilizing large 2-1/2", greasable urethane bushings. The arms bolt directly into the stock location, and position the axle for the proper caster and wheel location. The lower mount point at the axle utilizes our popular cam lock design, making it adjustable for 4" or 6" of lift.

Engine specific front coil springs are designed to not only ride great, but will hold up over the long haul. A 1-1/2" solid steel track bar is included to properly center the axle after lifting. This track bar features new oversized, high-durometer (hardness) urethane bushings for long term performance and improved handling. The system is comes with custom valved Zone hydraulic or choose to upgrade to the Nitro shocks for better towing and handling performance.

The rear is lifted with a 5" block used to replace the factory block instead of stacking blocks. This system is also one of the easiest installations on the market becuase of the use of a front track bar and rear block kit. If you are looking to not only lift your Super Duty, but improve the looks, strength, and feel of your suspension, choose the Zone Offroad radius arms system.

Truck Accessory Liquidators is the largest national distributor of Zone Offroad suspension lift kits for good reason. Our prices are guaranteed low, our product knowledge and friendly service top shelf, and our never out of stock policy assures your Zone Offroad product will ship the same day if your order is placed before 1pm EST Monday -Friday.

    NOTICE: Zone OffRoad Products strongly recommends installation of products be done by a certified mechanic. If this does not occur be certain the person(s) installing the product read understand and follow all instructions and warnings pertaining to the application before installation.

    WARNING: Zone OffRoad Products does not recommend the use of a body lift in conjunction with a suspension lift 'Kit' or 'System'.

    PRODUCT SAFETY WARNING

    Installation of suspension lift kits or any other lifting kits or devices will raise the center of gravity. For this reason, Zone OffRoad Products urges that extreme caution be used when encountering driving conditions which may cause vehicle imbalance. Furthermore, the driver's field of vision and judgment will not be as good due to the height of the vehicle. Due to the installation of larger tires, the speedometer will read slower than the actual speed being traveled and more distance will be required to stop the vehicle. It is the owner's responsibility to caution and warn any potential driver of the vehicle about these driving and handling conditions.

    Zone OffRoad Products will not be held liable or responsible for damages or personal injuries resulting from the use of lifting devices and/or related products. The tires and rims should be changed to sufficiently increase the vehicle's total overall width and stability to help accommodate lifting devices.

    Zone OffRoad Products also recommends that the steering system on lifted vehicles be appropriately corrected to reduce steering stress and angles. Once completed, the vehicle should be inspected by a professional mechanic including such areas as the steering system, brake system, speedometer re calibration, and clearance, for tire and suspension travel and tightness of all installed products. Every Zone OffRoad Products suspension kit includes a "Driver Warning" decal and the literature explaining this information which should be read and understood completely before driving, and the decal should be placed in a position clearly visible by the driver and all occupants.

    NOTICE: Most states have some type of law limiting vehicle height. The amount of lift allowed, and how the lift can be achieved, varies greatly. Several states offer exemptions for farm and commercial registered vehicles. It is the vehicle owner's responsibility to check state and local laws to ensure that their vehicle will be in compliance.

    Zone OffRoad Products reserves the right to make changes in design, materials, specifications and product changes as deemed necessary without prior notice and without assuming and obligation to modify any product previously manufactured. Obligation or liabilities will not be assumed with respect to similar products.
