If you're looking to elevate your fourth-generation Ford Super Duty, you might want to check out Rough Country's 6-inch Radius Arm Coilover Conversion Suspension Lift. This isn't just any lift kit; it's a complete package designed for those who want to push their truck to new limits without sacrificing that smooth factory ride. Seriously, you can run up to 37-inch tires and still enjoy a comfortable drive—it's a game changer.

One thing I’ve learned over the years is that when you mess with a vehicle's suspension, keeping everything in the right geometry is key to maintaining ride quality. That’s where Rough Country really shines. Their 6-inch Radius Arm Suspension Lift comes with these ultra-durable Radius Arms that fit right into the factory mounts. This means an easier install and angles that are closer to what the factory intended. We’re talking about beefy 27-pound arms that dwarf the stock ones and come with tough rubber bushings to soak up vibrations—trust me, your back will thank you on those long drives.

Then there's the suspension itself. This kit replaces the factory independent coil shock and coil setup with a serious upgrade: a 2.5-inch piston, nitrogen-charged, 8-stage adjustable Vertex Coilover. The monotube design and external reservoir mean better oil capacity and improved damping sensitivity. In fact, this setup boasts a whopping 56% greater fluid capacity than your average reservoir shock. So, whether you're hitting the trails or just cruising around town, you’ll notice the difference in control and comfort.

Now, let’s talk installation. You’ll need to do some cutting and drilling, so it’s not a walk in the park. Roughly 6-10 hours is a good estimate to get everything in place, but if you’re handy, you can knock it out at home. Just make sure you have the right tools and maybe a buddy to help out.

And for those of you who like to know your investment is protected, this kit comes with a limited lifetime replacement warranty against manufacturer defects. That means if something goes wrong due to structural or workmanship issues, you’re covered. It’s nice to have that peace of mind when you’re decking out your truck.
