What a McGaughys suspension lift is and how it changes your truck

A McGaughys suspension lift is an aftermarket kit that raises the frame and body of your truck higher off the ground by replacing or modifying the suspension components. McGaughys is a manufacturer based in Texas that makes lift kits for trucks and SUVs — they sell the physical parts you install, not a service. The lift works by using taller springs, shocks, control arms, or a combination of these to increase the distance between your frame and the wheels.

The result is more ground clearance under your truck and the ability to fit larger tires. A McGaughys lift typically raises your truck between 2 and 6 inches, depending on which kit you buy. The company makes kits for specific truck models — a kit for a 2014 Chevy Silverado is different from one for a 2020 Ford F-150 — so you need to know your exact year, make, and model before ordering.

McGaughys kits come as a complete package with all the parts you need for installation. You do not buy the springs separately from the shocks or the control arms separately. This matters because all the pieces are engineered to work together at the height the kit is designed for.

Key Takeaways

  • McGaughys lift kits raise your truck's frame by replacing suspension springs, shocks, and control arms with taller versions designed to work as a matched set.
  • Lift heights range from 2 to 6 inches and are specific to your truck's year, make, and model — ordering the wrong kit will not fit.
  • Installation requires removing your wheels, unbolting old suspension parts, and bolting in new ones, which takes a full day at a shop or longer if you do it yourself.
  • A lifted truck sits higher but may ride rougher on bumps, wear tires faster, and affect your speedometer and fuel economy until you recalibrate.
  • McGaughys offers different suspension designs — coil spring, leaf spring, and air suspension kits — and the right choice depends on your truck's original setup and how you plan to use it.

The main types of McGaughys lift kits and how they differ

McGaughys makes three broad categories of lift kits, and which one you need depends on what your truck came with from the factory. A coil spring lift replaces the coil springs in your front suspension with taller ones and usually includes new shocks and control arms. This is the most common type for trucks like the Chevy Silverado and GMC Sierra. A leaf spring lift works on trucks that use leaf springs in the rear — it stacks additional leaves or replaces the existing springs with taller ones. Some trucks use both coil springs in front and leaf springs in the rear, so you may need a kit that addresses both.

McGaughys also makes air suspension kits for trucks equipped with air springs from the factory. These kits replace the air springs with new ones calibrated for a higher ride height. Air suspension lifts are more expensive than coil or leaf spring lifts but offer a smoother ride because air absorbs bumps better than metal springs.

Beyond the spring type, McGaughys kits come in different heights. A 2-inch lift is mild and keeps your truck close to stock ride quality. A 4-inch lift is popular for trucks that want noticeable height and room for 33-inch tires. A 6-inch lift is aggressive and requires more modifications — you may need to add a transmission cooler, adjust your driveshaft, or modify your exhaust to avoid rubbing.

What happens during installation and what to expect afterward

Installing a McGaughys lift kit is a full suspension replacement, not a quick bolt-on. The process starts with lifting your truck on a hoist and removing the wheels. The technician then unbolts the old springs, shocks, and control arms — this can take several hours because bolts are often tight and corroded. Once the old parts are out, the new McGaughys components go in, usually in the reverse order. The whole job typically takes 6 to 10 hours at a professional shop, depending on your truck's condition and whether any bolts are stuck.

After installation, your truck will sit noticeably higher, and the ride will feel different. A coil spring lift often rides firmer than stock because the springs are stiffer to support the extra height. You may notice more bounce over bumps, especially if you do not add weight to the truck bed. Your speedometer will read slightly high because your tires are now larger in diameter — a shop can recalibrate this electronically on newer trucks, or you can use a speedometer corrector. Your fuel economy will drop by 1 to 3 miles per gallon because your truck is heavier and less aerodynamic.

Alignment is critical after a lift. Your wheels need to be re-aligned to factory specifications for your new height, or your tires will wear unevenly and your steering will pull. Most shops include alignment in the lift installation price, but confirm this before you pay. You should also have your alignment checked again after 500 miles to catch any settling.

Tire size and wheel fitment after a McGaughys lift

One reason people install a McGaughys lift is to fit larger tires. A stock truck might come with 31-inch tires; a 4-inch lift gives you room for 33-inch or even 35-inch tires depending on your wheel offset and suspension geometry. Larger tires improve ground clearance and look more aggressive, but they also slow acceleration, reduce fuel economy, and put extra stress on your drivetrain.

The limiting factor is wheel fitment — how much space exists between the tire and your truck's body and suspension. A McGaughys lift increases this space, but it does not increase it infinitely. If you go too large, the tire will rub on the fender, frame, or suspension components when you turn or hit a bump. A shop can tell you the maximum tire size for your specific truck and lift height. Going one size larger than recommended is sometimes possible with minor modifications like trimming the fender liner, but going two sizes larger usually requires cutting metal.

Wheel offset also matters. A wheel with a negative offset (dish) sits further out from the hub, which can cause rubbing. A wheel with a positive offset sits closer to the hub. McGaughys does not make wheels, so you choose your own, but a suspension shop can advise you on what offset works with your lift height.

Cost and labor considerations for a McGaughys lift

A McGaughys lift kit itself costs between $800 and $3,000 depending on the height and type. A 2-inch coil spring lift is on the lower end; a 6-inch air suspension lift is on the higher end. This is the parts cost only — you still need to pay for installation labor.

Installation labor at a professional shop typically runs $1,000 to $2,000, again depending on complexity and your truck's condition. If your truck has rusted bolts or damage to the suspension, labor can run higher. Some shops charge by the hour (usually $100 to $150 per hour) and some charge a flat rate for your specific truck model. Getting quotes from two or three shops is worth the time because prices vary widely.

If you install the kit yourself, you save the labor cost but need the right tools — a hoist or jack stands, a socket set, a torque wrench, and an alignment machine or access to one. Most home garages do not have an alignment machine, so you would still need to pay a shop for that step. Self-installation also takes longer — plan on a full weekend or more if you are not experienced.

How a McGaughys lift affects handling, braking, and warranty

Lifting your truck changes how it handles. The center of gravity moves higher, which increases body roll in corners. Your truck will lean more noticeably when you turn at speed. Braking distance may increase slightly because the weight is distributed differently. These changes are usually mild with a 2 or 4-inch lift and more noticeable with a 6-inch lift. Aggressive driving or towing when ready after a lift installation is not recommended — give yourself time to adjust to the new feel.

A McGaughys lift may void your truck's factory warranty on suspension and drivetrain components. Check your truck's warranty documents or call your dealer before installation. Some dealers will honor the warranty as long as the lift did not directly cause the failure, but others take a harder line. This is worth clarifying in advance.

McGaughys itself offers a limited warranty on its parts — typically one year against defects in materials and workmanship. This covers the springs, shocks, and control arms if they fail due to a manufacturing flaw, but not if they fail due to abuse, off-road use, or improper installation. Keep your receipt and the warranty paperwork.

Maintenance and long-term durability of a lifted suspension

A McGaughys lift does not require special maintenance beyond what your truck already needs. You still change the oil, rotate the tires, and replace brake pads on the same schedule. However, a lifted truck with larger tires does wear components faster. Your shocks will wear out sooner because they work harder over bumps. Your tires will wear faster because they are heavier and the suspension geometry is different. Budget for shock replacement every 50,000 to 75,000 miles instead of the 100,000 miles you might get from stock shocks.

Rust is a concern in cold climates. The new suspension components are steel and will rust if exposed to road salt. McGaughys parts are not stainless steel, so you may see surface rust after a few winters. This is cosmetic and does not affect function, but if rust bothers you, you can explore a protective coating or undercoat your truck annually.

Off-road use accelerates wear. If you plan to take your lifted truck on rough trails, expect to replace shocks and bushings more often. McGaughys makes some kits specifically for off-road use with heavier-duty shocks and reinforced control arms, but these cost more than street-focused kits.

Frequently Asked Questions

Will a McGaughys lift damage my truck's transmission or engine?

No, a suspension lift does not directly affect your transmission or engine. However, larger tires increase rolling resistance, which makes your engine work harder and can reduce fuel economy by 1 to 3 miles per gallon. If you tow heavy loads with a lifted truck, the extra strain on the drivetrain may shorten component life, but this is not damage — it is accelerated wear.

Can I install a McGaughys lift myself without a shop?

Yes, if you have mechanical experience, the right tools, and access to an alignment machine or shop. The kit itself is straightforward — remove old parts, bolt in new ones — but alignment is critical and requires professional equipment. Many people install the kit themselves and pay a shop for alignment only, which saves money on labor.

What is the difference between a McGaughys lift and a body lift?

A suspension lift raises your frame and suspension, giving you real ground clearance and room for larger tires. A body lift raises only the truck bed and cab, leaving the suspension at stock height. Body lifts are cheaper but do not improve ground clearance or tire capacity. McGaughys makes suspension lifts, not body lifts.

Do I need new shocks when I install a McGaughys lift kit?

Yes, McGaughys kits include new shocks matched to the spring height. Using old shocks with new springs will result in poor ride quality and premature wear. The shocks are part of the kit, not an add-on.

How long does a McGaughys lift last?

The springs and control arms typically last the life of your truck if maintained. The shocks wear out faster — expect 50,000 to 75,000 miles before replacement. Bushings and ball joints may need replacement after 100,000 miles depending on driving conditions. Regular maintenance and alignment checks extend the life of all components.
