Zone Offroad 6" Radius Arm Drop Suspension System

1/4" boxed radius arms with oversize greasable bushings
Diesel or gas specific coil springs for an accurate lift height and proper ride quality
Increased ground clearance and better looks than a radius arm drop system
Track bar bracket and dropped pitman arm included to correct steering geometry
Sway bar drop brackets to maintain the OE sway bar angle
Front bump stop spacers
Front and rear brake line relocation brackets
Steering stabilizer relocation bracket
5" rear block with integrated bump stop
Dual rear add-a-leafs
Designed to level the truck with removal of the factory block

Lift your Super Duty with Zone Offroad'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, gas & diesel specific coil springs will not sag to provide you the lift to clear 37's 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, will level the truck, and is also designed to shift the axle forward to ensure the tire stays centered in the rear wheel well.
For a top shelf 6" lift without the top shelf price, buy from Zone Offroad with an elevated level of customer service to back it up.
