Rough Country 6" Lift Kit Coilover Conversion for Ford F-250/F-350 Super Duty 08-10 - 53959

So, you’re thinking about giving your second-gen Ford Super Duty a serious lift? Let me tell you, Rough Country’s 6-inch Radius Arm Coilover Conversion Suspension Lift is the way to go. This kit has everything you need to transform your truck while keeping that smooth ride you love. You’ll be ready to run up to 37-inch tires without sacrificing comfort—how cool is that?

Now, let’s talk about durability. When you're messing with suspension, it’s crucial to maintain the factory geometry as much as possible. That’s where these ultra-durable Radius Arms come in. They bolt right into your factory mounts, making the install a breeze and keeping those angles factory-like. Each arm weighs in at 27 pounds—way beefier than stock—and they come with tough rubber bushings that soak up vibrations like a champ. Plus, the kit features heavy-duty coilover mounts and top-mounted reservoir brackets made from 1/4-inch steel. You’re not just upgrading; you’re beefing up your ride.

What’s really impressive is the 2.5-inch piston, nitrogen-charged Vertex Coilovers that replace your factory setup. These bad boys have an external reservoir that boosts oil capacity and enhances damping sensitivity. In fact, Rough Country’s design gives you 56% more fluid capacity compared to your average shock. That means better control and a smoother ride when you hit those bumpy trails.

Now, I won’t sugarcoat it—installation requires some cutting and drilling, so you’ll want to set aside about 6 to 10 hours to get it all done. But if you’re handy, you can definitely tackle this at home without too much hassle.

And hey, Rough Country backs this lift kit with a limited lifetime replacement warranty. That’s right, you’re covered against manufacturer defects, so you can hit the road (or the off-road) with peace of mind.

Features:
  • 100% bolt-on installation—no guesswork here.
  • Fabricated blocks are built stronger and last longer than cast blocks.
  • Includes an adjustable alignment cam at the axle for caster adjustments.
  • Heavy-duty radius arms with durable rubber bushings for top-notch vibration absorption.
  • Increased ground clearance to tackle those tough spots.
  • Levels the front with the rear for a balanced look.
  • New radius arms help keep factory angles intact.
