Bring your SuperDuty to new heights with this complete suspension system from Zone! This Zone Offroad 4" radius arm suspension lift features tough replacement 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 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 because 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.
Shock Options - We offer this kit with several shock options:
- No Shocks: If you'd rather supply your own shocks, no problem, we give you this option.
- Nitro Series Shocks: Zone Nitro Series shock absorber offers stock-like control and performance with fully displaced valving for improved compression and extension travel. This vehicle specific valving is pressurized with 50 psi nitrogen gas; this gas charge ensures split second response and reduced aeration. Combine these features with the special Fluon-banded piston and this shock is built to perform!
- Fox Adventure Series Shocks: Built specifically to compliment your Zone lift kit, FOX's proven damping technology provides a comfortable on-road ride and predictable off-road handling in a variety of conditions. Their monotube design uses an internal floating piston (IFP) to separate the shock oil from the high-pressure, nitrogen-charged gas chamber, preventing oil aeration for fade-free performance in rough terrain.

Be careful purchasing this.
We bought this for an ice-cream maker - they never sent the initial startup you bought this email. So I had to fight with them that yeah we bought it.
Then they classified it as an ice-maker - important for pictures later . Then we had bought the machine and insurance partially with gift cards not a big deal, right? - well, the machine cost $300ish but showed on the receipt total as $180ish - guess which amount they wanted to pay out for? Then they wanted pictures showing serial number and such on the machine. I sent them pictures of each side clearly showing no stickers. Take more pictures of the front and top because what you took wasn't good - MAYBE because you thought it was an ice-maker... Take a picture showing what doesn't work - it will spin and move, but the compressor broke so it won't get cold - NOT GETTING COLD is something I can't show... it was fun being told to take a video showing it not getting cold only to tell them yeah no I am not wasting my time doing that.
There was a lot of repetitive stuff but they did eventually pay out the correct amount. Would I buy it again? Yes. Is it as easy as they make it out to be? No.
Did I WANT to give this review? No, because I didn't want to leave a negative review. I am a very charming, nice, and personable guy that didn't want to be mean. Keep pestering me enough about leave a review about how great we are and you will get the review you probably did not want.

You can trust ASURION warranties!
ASURION was fantastic as always. Purchased a Nespresso machine for my DIL which she absolutely loved and two months before warranty expired it started leaking which broke her heart. ASURION stood behind their warranty and refunded purchase price which I transferred to my DIL so she could purchase another machine. That’s why I never hesitate to buy their warranty’s and why I love shopping Amazon! Both companies represent their clients well. Thanks to both!

Quick,immediate action
Very quick refund. I reported the issue, same day reply with instructions on how to return, free postage and as soon as Asurion was notified id dropped off at UPS, within the hour my refund was in my account. A pleasant experience as no waiting period, nothing. I’m able to replace product almost immediately.
Thank you, I’ll be covering all my expensive items with this company. Five stars all around.
