Product Info

This kit fits 08-10 Ford F250-350s WITHOUT rear overload springs only!

Lift your Super Duty with Zone's 6" Radius Arm Suspension Lift for an attention grabbing, smooth riding, complete, and affordable system. For less than the cost of some radius arm drop kits on the market, you can buy this system with bullet proof radius arms that provide more ground clearance, better looks, and a big strength improvement over the stockers. American made, diesel specific coil springs will not sag to provide you the lift to clear 37s and a ride you might not expect from a system this price competitive.

This system includes everything you need and more, including a dropped pitman arm and track bar relocation bracket, but for a complete list check out the features tab. To avoid stacking rear blocks or going too tall with a single block, Zone includes a 5" cast iron block with an integrated bump stop as well as dual add-a-leafs. This block & AAL system will reduce spring wrap, level the truck, and is also designed to shift the axle forward to ensure the tire stays centered in the rear wheel well.
