A 6-inch Rough Country lift raises your truck's frame and body together, increasing ground clearance and changing how your suspension handles weight and movement

A 6-inch suspension lift from Rough Country is a complete system that replaces your truck's factory springs, shocks, and related parts with taller components. The result is that your truck sits 6 inches higher than stock. This extra height lets you fit larger tires, clear obstacles on rough terrain, and gives your truck a different stance. But it also changes how your truck rides on pavement, how much weight it can safely carry, and what maintenance it will need going forward.

Rough Country is one of the larger aftermarket suspension manufacturers, and their 6-inch kits are designed to work with specific truck models — a kit for a Ford F-150 is different from one for a Chevrolet Silverado. The kit includes new coil springs or leaf springs (depending on your truck), new shocks, new control arms or track bars, and sometimes new brake lines or sway bar links. Installation typically takes a shop 4 to 8 hours and costs between $800 and $1,500 in labor on top of the kit price.

Key Takeaways

  • A 6-inch Rough Country lift raises your entire truck, not just the suspension, and requires replacing springs, shocks, and related parts as a system.
  • The lift lets you fit 33-inch or 35-inch tires instead of stock sizes, but larger tires reduce fuel economy and can affect speedometer accuracy.
  • Your truck's payload capacity (how much weight you can carry in the bed) drops when you lift it, and you may need a brake line extension kit to prevent brake fluid leaks.
  • Rough Country kits are designed for specific truck models and years, so you must confirm your truck's exact year and cab style before ordering.
  • A lifted truck will ride differently on highways — stiffer and sometimes bouncier — and may need alignment work after installation to prevent uneven tire wear.

How the lift system works and what it replaces

Your truck's factory suspension uses springs to support the weight of the vehicle and absorb bumps. A 6-inch lift replaces those springs with taller ones, which sit higher on the frame. Rough Country kits also include new shocks (the dampers that control how fast the springs compress and extend) because factory shocks are too short for the new spring height. If your truck has coil springs in the front, the kit swaps them for taller coils. If it has leaf springs in the rear, the kit includes new, longer leaf packs.

The kit may also include new control arms, which connect the wheels to the frame and keep them aligned as the suspension moves. Factory control arms are angled for stock ride height; at 6 inches higher, they would pull your wheels out of alignment. Rough Country kits include adjustable control arms or new fixed arms designed for the lifted height. Some kits also include a new track bar (on solid-axle trucks) or sway bar links to keep the suspension geometry correct.

Installation is not a bolt-on job. A shop will lift your truck on a hoist, remove the wheels, disconnect the factory springs and shocks, unbolt the control arms, and then install the new components in reverse order. The truck must be at ride height (wheels on the ground under its own weight) when the final bolts are tightened, so the suspension is properly loaded. If bolts are tightened while the truck is on a hoist, the suspension will settle unevenly once it's driven.

Tire size and ground clearance changes

The main reason people buy a 6-inch lift is to fit larger tires. Factory trucks usually come with 30-inch or 31-inch tires. A 6-inch lift gives you room for 33-inch tires without rubbing the fenders or suspension, and sometimes 35-inch tires depending on your truck model and whether you trim the fenders. Larger tires look more aggressive and do clear rocks and obstacles better on trails.

But larger tires have real costs. A 35-inch tire weighs more than a 31-inch tire, which means your engine works harder and fuel economy drops — typically by 1 to 3 miles per gallon. Larger tires also roll slower, so your speedometer will read higher than your actual speed. If your speedometer says 60 mph but you're actually going 58 mph, you may get a ticket for speeding you didn't know you were doing. Many shops can reprogram your truck's computer to correct this, but it costs extra.

Ground clearance — the distance from the lowest point of your truck to the ground — increases by roughly the tire size increase plus the suspension lift. If you go from a 31-inch tire to a 35-inch tire and add a 6-inch lift, your ground clearance increases by about 8 to 10 inches. This helps on rough terrain, but it also raises your center of gravity, which makes your truck more prone to rolling on sharp turns at highway speed.

Changes to payload capacity and towing

Your truck's payload capacity is the maximum weight you can safely carry in the bed. This number is printed on a sticker inside the driver's door. A 6-inch lift reduces payload capacity because the taller springs are softer (they have to be, to support the extra height without being too stiff), and softer springs sag more under load. The reduction is usually 300 to 500 pounds, depending on the kit and your truck model.

If you regularly haul heavy loads — landscaping materials, firewood, tools — a 6-inch lift may not be the right choice. Rough Country publishes the payload reduction for each kit, so check the spec sheet for your truck before ordering. Some kits are designed to maintain payload better than others, but none restore it to factory levels.

Towing capacity (the weight you can pull behind your truck) is usually less affected than payload, because towing depends more on engine power and transmission cooling than suspension stiffness. However, a lifted truck sits higher, which changes the angle of the trailer hitch. If the hitch angle is too steep, the trailer tongue can lift off the ball, which is dangerous. You may need a different hitch or a hitch extension to keep the angle correct.

Brake system changes and safety considerations

When you lift your truck 6 inches, the brake lines — the tubes that carry brake fluid from the master cylinder to the wheels — become too short. As the suspension compresses (when you hit a bump or brake hard), the lines stretch and can tear or leak. Rough Country kits include new, longer brake lines or a brake line extension kit to prevent this. If your kit does not include them, you must order them separately; driving without them risks brake failure.

A lifted truck also sits higher, which changes how weight transfers when you brake. The higher center of gravity means more weight shifts to the front wheels during braking, which can cause the rear wheels to lock up more easily on slippery surfaces. Some drivers add a load-sensing proportioning valve to the brake system to prevent this, but it is not always necessary — it depends on your truck and how you drive.

Lifting also affects your truck's stability on highways. The taller suspension and larger tires increase wind resistance and make the truck more prone to swaying in crosswinds. Driving at highway speed in strong wind requires more attention. On sharp turns, the higher center of gravity means the truck leans more, which can feel unstable if you are used to stock height.

Ride quality and alignment after installation

A lifted truck rides differently than a stock truck. Factory suspensions are tuned to be comfortable on pavement — they absorb small bumps smoothly and keep the truck level. A 6-inch lift, especially with stiffer springs needed to support the extra height, tends to be bouncier and transmits more road noise into the cab. On rough terrain, this is an advantage; on the highway, it can be tiring.

After installation, your truck must be aligned. Alignment is the angle at which your wheels point relative to the frame. A lift changes these angles, and if they are not corrected, your tires will wear unevenly and your truck will pull to one side. A shop will measure the angles and adjust the control arms to bring them back to spec. Alignment costs $150 to $300 and is essential — skipping it will destroy your tires in a few thousand miles.

Some lifted trucks also develop a slight vibration or shimmy at highway speed, especially if the tires are not perfectly balanced or if the suspension geometry is slightly off. This usually goes away after a few hundred miles as the suspension settles, but if it persists, the shop should recheck the alignment and tire balance.

Maintenance and long-term durability

A lifted truck requires more frequent maintenance than a stock truck. The taller suspension puts more stress on the frame, and the stiffer springs and shocks wear out faster. Rough Country shocks are not as durable as premium brands like Bilstein or Fox, so you may need to replace them every 40,000 to 60,000 miles instead of the 80,000 to 100,000 miles you might get from factory shocks.

The larger tires also wear faster because they are heavier and work harder. Tire rotation every 5,000 miles (instead of the usual 7,500) helps, but you should expect to replace them sooner. The increased wear on suspension components — control arm bushings, ball joints, sway bar links — means more frequent shop visits and higher repair costs over time.

Rough Country kits come with a limited warranty, usually covering defects in materials and workmanship for one year or 12,000 miles. The warranty does not cover wear items like shocks or bushings, and it does not cover damage from off-road use or improper installation. Keep your receipt and the kit documentation in case you need to make a warranty claim.

Frequently Asked Questions

Will a 6-inch lift void my truck's warranty?

It may. Most manufacturers consider suspension modifications a reason to deny warranty coverage on related systems — engine, transmission, and frame. Check your owner's manual or call your dealer before installing a lift. Some dealers will honor the warranty if the lift is installed by a certified shop and the truck is maintained properly, but others will not.

Can I install a Rough Country lift myself?

You can if you have a hoist, a full set of tools, and experience with suspension work. Most home mechanics should have a shop do it. The job requires precise torque specifications, proper ride-height measurement, and alignment afterward. A mistake can make your truck unsafe to drive. Labor costs $800 to $1,500, but it is worth it for the safety and durability of the finished job.

What is the difference between a 6-inch coil-over lift and a 6-inch spring lift?

A coil-over lift uses coil springs mounted over the shock absorber, which allows for more adjustability and better ride quality. A spring lift uses separate coil or leaf springs and shocks. Rough Country makes both types. Coil-overs are more expensive but ride better and are easier to adjust for different loads. Spring lifts are cheaper and simpler but less adjustable.

Do I need new wheels and tires when I install a lift?

Not necessarily. If your factory tires fit under the lifted truck without rubbing, you can keep them. But most people buy new tires at the same time because larger tires are the main reason for lifting. New wheels are optional — you can use your factory wheels with larger tires, though many people prefer the look of aftermarket wheels.

How much does a complete 6-inch Rough Country lift cost?

The kit itself costs $400 to $800 depending on your truck model. Labor for installation is $800 to $1,500. Alignment costs $150 to $300. New tires and wheels can cost $1,000 to $2,500. A complete lift job with tires and wheels typically runs $3,000 to $5,000 total. Prices vary by region and shop.
