Ford unveiled the fourth-generation Super Duty at the 2015 State Fair of Texas, and it arrived for the 2017 model year as the first ground-up redesign since the platform launched in 1999. The frame is 95 percent high-strength steel, the body is 6000-series aluminum alloy, and the result is a truck that shed up to 350 pounds compared to the outgoing generation while gaining a stronger frame, fortified axles, and a more capable drivetrain. The F-350 is a Class 3 heavy-duty truck available as a crew cab, extended cab, standard cab, and cab-and-chassis, in both single-rear-wheel and dual-rear-wheel configurations, with 4WD or RWD.
Engine options across the generation include the 6.2L gasoline V8, the 7.3L Godzilla gasoline V8 introduced with the 2020 refresh, and the 6.7L Power Stroke turbodiesel V8, which received a significant output bump for 2020 alongside the new 10-speed TorqShift automatic transmission. The 2020 refresh also brought a revised grille, new wheel options, and upgraded interior materials. Trims run from the work-ready XL through XLT, Lariat, King Ranch, Platinum, and the top-shelf Limited that debuted for 2018. The Tremor off-road package arrived for 2020, adding factory lift, 35-inch tires, and a locking rear differential. This generation is one of the most-documented heavy-duty platforms in Our Gallery, and the aftermarket depth to match it is real.
A leveling kit raises the front of the F-350 to eliminate the factory front rake, bringing the nose up level with the rear. That opens a little extra front-tire clearance and gives the truck a more aggressive, planted stance without changing the rear ride height. On a dually, the leveling kit is often the first and most impactful move: the truck sits level, the proportions tighten up, and 35-inch tires on 20-inch wheels become a clean, bolt-on reality on most builds. Our Gallery shows the leveling kit as the single most common suspension move on this generation, with 20x10 wheels on 35-inch tires showing up across the majority of leveled builds. Most of those bolt on clean with no modification.
A 4-inch suspension lift is where the F-350 starts to look seriously tall. New shocks matched to the added height, geometry-correction hardware, and often upper control arms on 4WD builds are part of a full kit at this height. The lift opens the door to 37-inch tires alongside the 35s that fit at the leveled stage, and the offset window pushes more negative for real wheel poke. A 22x12 wheel on 35-inch tires bolts on clean at this height on most builds; stepping to 37-inch tires at 4 inches of lift typically calls for minor fender trimming on most builds, with a touch of rub at full steering lock being common. Wheel sizes from 20 to 24 inches all work here.
A 6-inch lift is a big lift on the F-350, and the builds that run it are built to be seen. Longer shocks, full geometry correction, and often new upper control arms are standard at this height. Tires climb to 37 inches as the common target, with 38s on the aggressive end. Offsets go sharply more negative here, with most builders running around -44 and the aggressive end pushing well past that for serious poke. A 22x12 at -44 on 37-inch tires is the setup our customers reach for most at this height, with most needing minor plastic trimming and a touch of rub at full lock. For the show-truck path, 24x12 wheels on 37-inch tires are well-documented at 6 inches of lift. The 8-inch-plus tier is where the platform goes full extreme: 26-inch wheels on 40-inch tires, documented in Our Gallery, for builders who want the boldest possible stance.
All three engines on the 2020 F-350 respond to a cold air intake. On the 6.2L and 7.3L gasoline V8s, a cold air intake sharpens throttle response and adds an aggressive induction note under hard acceleration. On the 6.7L Power Stroke diesel, a high-flow intake improves airflow into the turbo system, supporting better spool and a more responsive pedal. The diesel intake pairs naturally with intercooler piping upgrades to keep charge temps down and the turbo breathing freely.
The 6.2L and 7.3L gasoline V8s both benefit from a cat-back exhaust system, replacing everything downstream of the catalytic converter while leaving the cat in place. The result is a deeper, more aggressive exhaust note and freer flow through the system. The 7.3L Godzilla in particular has a strong exhaust character that a cat-back brings out well. On the 6.7L Power Stroke diesel, the legal upgrade is a DPF-back system, replacing everything downstream of the diesel particulate filter. The benefit here is reduced backpressure, a little less weight, and freer breathing behind the filter. Frame the diesel upgrade around flow and weight, not sound: the DPF does the heavy acoustic work and stays in place.
Beyond intake and exhaust, the 2020 F-350 supports a solid range of bolt-on performance work. Performance tuners let you optimize fueling, shift points, and throttle calibration for the combination of mods you're running, and a supporting tune gets the most out of any intake and exhaust combination. Differential upgrades and ring-and-pinion regearing are popular on lifted builds where larger tires change the effective gear ratio and hurt drivability. Upgraded brake kits, including big brake setups with larger rotors and performance pads, are a smart move on a truck running larger-than-stock wheels and tires, where the added rotating mass increases stopping demands. Transmission upgrades and driveshaft work round out the drivetrain side for builds pushing the platform hard.
On the 2020 F-350, lighting and exterior work is where the build's character gets defined: show-truck presence after dark, a front end that matches the stance, and protection and utility gear for the builds that work as hard as they look.
For the show-truck path, the F-350's large front end and tall stance make it a strong canvas for presence lighting. LED headlight and tail-light upgrades with projector optics, halo rings, or sequential turn signals change the truck's face and give it a distinctive look day and night. Grille-integrated lighting and amber marker accents add visual depth to the front end. Underbody lighting shows off the suspension hardware underneath at shows and meets, and cab marker lights are a classic Super Duty detail worth upgrading to LED for a cleaner, brighter look.
For the off-road and trail path, the F-350 platform supports a full functional lighting build. Bumper-mounted LED light bars throw a wide spread for work and trail use. Ditch lights mounted at the A-pillar throw focused light to the sides for trail navigation. Pod lights and fog light upgrades fill in the gaps. Rock lights mounted to the undercarriage put light on the ground for low-speed trail work and obstacle reading. These are functional tools, and they earn their place on builds that actually use the truck off-road.
On the exterior, the show path starts with a grille swap and hood upgrade to match the lifted stance, then moves into fender flares to cover wider-than-stock tires and protect the paint from road debris the tires kick up. Running boards and power steps make entry and exit easier on a lifted truck. Aftermarket front and rear bumpers, including winch-mount options for the off-road path, change the truck's profile and add recovery capability. Bed covers, bed racks, and bed storage accessories keep the cargo area organized and protected. Mud flaps and rocker protection guard the lower body on a truck that sees real use.
Inside, the F-350 spends a lot of time as a work truck, and the interior upgrades that matter most reflect that. Heavy-duty floor liners front and rear protect against mud, water, and debris. Seat covers protect the factory upholstery on work-spec trims and add a custom look on higher trims. Interior trim kits and dash accents dress up the cabin on Lariat, King Ranch, and Platinum builds. Storage solutions keep the cab organized on trucks that carry tools and gear daily.
Good: A leveling kit to eliminate the factory front rake and level the truck front-to-rear, with the factory shocks retained. Better: A 4-inch suspension lift with new shocks matched to the added height, geometry-correction hardware, and upper control arms on 4WD builds. Best: A 6-inch or larger suspension lift with full geometry correction, new upper control arms, upgraded shocks, and supporting driveline hardware for the added height and tire size.
Good: A cold air intake on the engine of your choice for improved throttle response and induction character. Better: A cold air intake paired with a cat-back exhaust on the gas engines or a DPF-back system on the diesel, with a supporting tune to optimize the combination. Best: Full intake and exhaust system, supporting tune, differential and regearing work for lifted builds, upgraded brake hardware, and transmission or driveshaft upgrades for builds pushing the drivetrain hard.
Good: Grille upgrade, running boards or nerf bars, bed cover, and mud flaps for a clean, functional look. Better: Aftermarket front bumper, fender flares to cover wider tires, upgraded LED headlights and tail lights, and rocker protection. Best: Full front and rear bumper package, hood upgrade, full fender flare set, complete LED lighting build including grille-integrated and underbody lighting for the show path or a full functional light bar and ditch-light setup for the off-road path, and full body protection.
Good: Heavy-duty front and rear floor liners and seat covers for protection. Better: Floor liners, seat covers, interior trim kit, and cab storage solutions. Best: Full interior protection package, upgraded seat covers or seat upgrades, complete interior trim and accent kit, and organized storage for work or overland use.
Good: 20x9 +1 with 35x12.50R20 on stock suspension, a clean and aggressive setup that almost always bolts on with no rubbing reported on most builds. Better: 20x10 -18 with 35x12.50R20 on a leveling kit, the setup our customers reach for most at this height, and it almost always bolts on clean with no rubbing. Best: 22x12 -44 with 37x13.50R22 on a 6-inch suspension lift, the boldest widely-documented setup on this platform, with most builds needing minor plastic trimming and a touch of rub at full lock.
Good: Capable, clean, and ready to work or cruise, a meaningful step up from stock without changing the truck's daily character. Better: Aggressive street presence, noticeably taller and wider, a truck that turns heads at the fuel stop and still hauls on the weekend. Best: Show-truck intent, maximum visual presence, the kind of build people circle in the parking lot and that earns its reputation on the road.
There's no single right answer, and that's the honest one. Builders who want the biggest visual impact fast usually start with a leveling kit and a wheel and tire package: it changes the truck's presence immediately and the fitment is well-documented across thousands of builds in Our Gallery. Builders focused on capability often start with suspension. Performance-first builders go intake and exhaust. Start where your goals are, and we can help you map the rest of the build from there.
Yes, and the smart move is to get pre-approved before you start building your cart. Pre-approval is fast, it tells you your budget upfront, and it means you can shop with confidence instead of guessing at the end. A full suspension and wheel package on an F-350 is a real investment, and financing lets you do it right the first time instead of piecing it together. Get pre-approved, then build the cart.
Absolutely. Our team handles both sides: fitment questions like which offset clears your fenders at a given lift height, whether a 37-inch tire needs trimming on a 4-inch lift, and how dually rear spacing affects your wheel choice, and install questions like how mods stack, what hardware you need, and the sequence for a full lift build. Call or reach out and we'll walk you through it.
Because we specialize in exactly this: aggressive fitment on heavy-duty trucks, proven across real builds. Our Gallery shows real F-350 Super Duty builds from our customers running the exact setups you're considering, so you're not guessing whether a 22x12 -44 on 37s clears at 6 inches of lift. You can see it. We also ship wheel and tire packages mounted, balanced, and ready to bolt on, so there's no extra step between your driveway and the road.
