Ford Super Duty Lift Kits & Leaf Springs Guide (05-23)

Choosing between Ford Super Duty lift kits and leaf springs comes down to one question: do you want a better ride, a taller stance, or both? On a 2005–2023 Ford F-250 or F-350, the front rides on coil springs and a solid axle while the rear sits on leaf packs, so the right upgrade depends on which end you are fixing. Below we compare five proven options we stock and ship from our Tampa, FL shop — from the ride-first Carli progressive leaf pack to a full 3-inch Eibach lift — with real lift heights, fitment years, and prices so you can match the part to your goal on the first try.

How Ford Super Duty Suspension Works (2005–2023)

The 2005–2023 Ford Super Duty uses a coil-sprung solid front axle located by radius arms and a leaf-sprung rear axle. Ford switched the front end from leaf springs to coil springs for the 2005 model year, and that layout carried through the 2008, 2011, and 2017 redesigns up to the current generation. This matters because it dictates which part you buy: the front is leveled or lifted with coil springs, coil spacers, or a coilover; the rear is raised and tuned with leaf springs, add-a-packs, or blocks.

From the factory, a Super Duty sits with a slight nose-down rake, and three-quarter-ton and one-ton diesels often sag further at the rear or front under the weight of the engine and a plow or fifth-wheel. A leveling kit raises the front 2 to 2.5 inches to erase that rake for a level stance and bigger tires. A lift kit raises the whole truck 3 inches or more for serious tire clearance. A progressive leaf spring pack trades the harsh OEM rear ride for a smoother, multi-rate spring while adding around 1 inch. Get the architecture right and the rest of the decision is easy.

Best Ford Super Duty Lift Kits & Leaf Springs: Quick Comparison

Here are the five Super Duty suspension upgrades we recommend most, ranked by what they do best. The table lists each kit’s type, lift height, fitment, and price so you can scan the right fit in seconds.

1. Carli Full Progressive Leaf Spring Pack – Best Ride Quality

The Carli Full Progressive Leaf Spring Pack is a complete rear leaf replacement that adds 1 inch of lift and dramatically improves ride quality on the 2005–2023 Ford F-250 and F-350. Instead of stacking an add-a-leaf onto the stiff factory pack, Carli replaces the entire rear spring with a progressive, multi-rate design that runs soft over small bumps and firms up under load. The result is more wheel travel, less axle wrap, and a planted feel on the highway, off road, and while towing.

Carli tunes the pack to a “light 3/4-ton” rate, so you keep usable payload while shedding the empty-bed harshness diesel owners complain about. One important fitment note: the F-250 version uses 2 main leaves while the stiffer F-350 pack adds a third main leaf, which is why F-350 owners feel the biggest improvement going to progressive springs. At $770 it is a premium part, but it is the single change that most transforms how a Super Duty rides.

2. Eibach Pro-Truck Lift Stage 1 – Best Complete Bolt-On Lift

The Eibach Pro-Truck Lift Stage 1 is the best complete bolt-on lift for a 2005–2016 Ford F-250 or F-350 4WD, raising the front 3 to 3.3 inches and the rear up to 1 inch. Unlike a spacer-only level, this is a matched system: it pairs Pro-Truck lift springs with Pro-Truck Sport monotube shocks front and rear, so you gain tire clearance without the rough, over-sprung feel that cheap lifts deliver. Eibach builds the springs with off-road race spring technology and backs the kit with a Million Mile Warranty.

At $930 it costs more than a leveling kit, but you are buying a tuned spring-and-shock package rather than a stack of spacers, and the 3-inch front lift clears a 35-inch tire on most trim levels. Plan on an adjustable track bar or a track-bar drop bracket to re-center the front axle, plus an alignment afterward. For owners who want a real lift with factory-like manners, this is the kit to beat.

3. Belltech 2.5in Leveling Kit – Best Leveled Stance

The Belltech 2.5in Leveling Kit is the best way to erase the factory nose-down rake on a 2005–2018 Ford F-250 or F-350 and run a taller front tire. It raises the front 2.5 inches to sit level with the rear, opening room for up to a 35-inch tire while keeping the truck’s tow-ready geometry. At $508 it lands between a budget spacer and a full lift, and Belltech includes the hardware to do the job right on the coil-sprung front axle.

A level stance is the most popular Super Duty modification because it improves the look, clears bigger meats, and helps a loaded truck sit flat. As with any height change, budget for a front-end alignment and consider extended-length shocks or shock extenders so the dampers work through their full range at the new ride height.

4. Fabtech 2in Leveling System – Best Budget Level

At $197.89, the Fabtech 2in Leveling System is the best budget way to level a 2017–2024 Ford F-250 or F-350 4WD. It raises the front 2 inches to match the rear and clear a slightly larger tire, using durable components designed to retain the factory ride. For owners who want the leveled look and a little more tire without spending four figures, this is the entry point.

A spacer-style level like this is the simplest Super Duty suspension job — it bolts to the coil-sprung front axle without disassembling the spring — but the same rules apply: get an alignment afterward, and add shock extenders if your factory shocks are near the end of their travel. It is the most cost-effective way into a leveled Super Duty.

5. Skyjacker Softride Rear Leaf Spring – Best for Big Lifts

When you are building a tall Super Duty, the Skyjacker Softride Rear Leaf Spring is the rear component you want behind a 6-inch lift system on a 2008–2014 Ford F-250 or F-350. Skyjacker builds the Softride pack from American steel with thinner, shot-peened leaves and bolt-style spring clips that cut inter-leaf friction, so a big-lift truck still rides better than a stack of cheap blocks would allow. The taper runs the full length of each leaf to spread loads and free up wheel travel.

At $393.68 for the rear pack, it is the spring that makes a 6-inch lift livable, distributing load evenly and resisting the bounce that plagues lifted three-quarter-tons. It is a system component rather than a standalone lift, so pair it with the matching front lift, track-bar correction, and longer shocks for the full build.

How to Choose the Right Super Duty Suspension

Start with your goal. If you want a better ride and minimal lift, a progressive rear leaf pack like the Carli is the single best change for a 2005–2023 F-250 or F-350. If you want a level stance and bigger tires, a 2 to 2.5 inch front leveling kit (Fabtech or Belltech) is the most popular and most cost-effective path. If you want real height and tire clearance, a matched spring-and-shock lift like the Eibach Stage 1 delivers 3 inches with factory-like manners, and a 6-inch system built around Skyjacker Softride rear springs goes taller still.

Three install realities apply to almost every Super Duty height change. First, plan on a front-end alignment any time you alter ride height — the solid front axle needs caster and toe set correctly, and many kits include caster cams to do it. Second, raising the front shifts the track bar, so an adjustable track bar or a track-bar drop bracket is needed to re-center the axle and keep the steering wheel straight. Third, factory shocks have a fixed length; at 2.5 inches and up you will want extended-length shocks or shock extenders so the dampers do not top out. F-350 owners should also remember their rear pack carries an extra main leaf, so the ride-quality gain from progressive springs is even bigger than on an F-250.

Finishing pieces matter too. New rear axle U-bolts are cheap insurance when you change a leaf pack, and a taller front lift usually needs radius arm drop brackets to correct pinion angle and caster. Buy the supporting hardware with the kit so the truck drives right the day it comes off the lift.
