The second-generation Ford F-350 Super Duty arrived for the 2008 model year as a ground-up redesign, bringing a completely new interior, a revised chassis, and the all-new 6.4L Power Stroke diesel with sequential turbochargers. The engine lineup covers serious ground: the 5.4L Triton V8 handles base-duty work, the 6.8L Triton V10 adds displacement for heavy towing, and the 6.4L Power Stroke is the one most builders chase. Available in Standard Cab, Extended Cab, Crew Cab, and Cab and Chassis configurations, with both 4WD and RWD, the platform spans everything from a bare work truck to a fully built show truck. The 8x170 bolt pattern is shared with the F-250 Super Duty, which means a wide and well-documented aftermarket. The dually configuration adds its own fitment dimension, and this generation has a strong, well-documented build community behind it. Whether you haul during the week or build for the lot on weekends, the second-gen F-350 is a proven canvas.
A leveling kit raises the front of the F-350 to eliminate the factory nose-down rake and bring the truck level front-to-rear. That extra front clearance opens the door to a larger wheel-and-tire package up front without rubbing. On a dually, the leveling kit is the most common first move: it cleans up the stance, makes the truck look intentional, and pairs naturally with 20-inch wheels and 35-inch tires. Most builders running a leveling kit go with a 20x12 at -44 offset on 35x12.50R20 tires, though a 20x10 at -19 or -24 on the same 35-inch tire is a popular, slightly more conservative route. Expect minor plastic trimming at this setup, and a slight rub at full steering lock is common on the more aggressive offsets.
A 3-to-4-inch suspension lift opens the wheel-and-tire envelope further and gives the F-350 a commanding road presence. At this height, 35-inch tires are the standard target and 20-inch wheels remain the most popular choice, with 22-inch wheels showing up regularly as well. The most-run combo at this tier is a 20x12 at -44 on 35x12.50R20 tires over a 4-inch lift. About half of these setups bolt on clean; the other half need a quick trim. A full lift kit at this height typically includes new shocks matched to the added ride height and often geometry-correction hardware to restore proper front-end angles. The result is a truck that sits noticeably taller, clears more tire, and still drives like a daily.
Push the 2008 F-350 to a 6-inch or 8-inch lift and the build changes character entirely. At 6 inches, 37-inch tires come into play alongside 20-inch and 22-inch wheels, with offsets going more aggressive. The most-run combos at this height include 20x12 -44 on 37x13.50R20 and 20x10 -24 on 37x13.50R20 tires. Step up to an 8-inch lift and the platform opens to 37-inch tires on 20-inch through 24-inch wheels, with offsets typically running from -24 down to -76 for serious poke. The 20x12 -44 on 37x13.50R20 is a proven, repeatable combo at 8 inches and almost always bolts on clean. For the boldest documented build on this platform, our customers have run 24x14 -76 wheels on 37x13.50R24 tires over an 8-inch lift: that is a full-blown show truck. A full lift at this height includes new shocks, geometry-correction hardware, and often upper control arms on 4WD models to restore proper ball-joint angles.
Every engine in the 2008 F-350 lineup responds to a cold air intake. On the 6.4L Power Stroke, a cold air intake pulls cooler, denser air into the turbo system, improving throttle response and letting the sequential turbos spool more freely. The 5.4L and 6.8L gas engines pick up a more aggressive induction note and a crisper throttle feel. The 6.4L diesel in particular benefits from reduced intake restriction, which pairs well with the intercooler and piping upgrades available for this platform.
On the 6.4L Power Stroke, a DPF-back exhaust replaces everything downstream of the diesel particulate filter. The real benefits are reduced backpressure, improved flow behind the filter, and a touch more turbo spool audible at the tailpipe. On the 5.4L and 6.8L gas engines, a cat-back system replaces everything downstream of the catalytic converter, leaving the cat in place. The V8 picks up a deeper, more aggressive exhaust note; the V10 gets a fuller, more pronounced sound that matches its displacement. Each engine has a worthwhile exhaust path.
The 2008 F-350 platform supports a solid range of supporting bolt-ons beyond intake and exhaust. Intercooler and piping upgrades on the 6.4L Power Stroke improve charge-air cooling under load. Performance tuners are available for this platform and can optimize fueling and shift points to get the most out of bolt-on combinations. Differential upgrades, ring and pinion gear sets, and axle components are well-supported given the platform's heavy-duty driveline. Brake upgrades are worth considering on any F-350 running larger-than-stock wheels and tires, where the added rotating mass increases stopping distances and brake load.
On a 2008 F-350, lighting and exterior work is where the build's character becomes visible: show-presence lighting for trucks built to be seen, functional lighting for trucks built to work, and exterior upgrades that match the stance the suspension creates.
For the show-truck path, LED headlight and tail-light upgrades are the starting point: projector housings, halo rings, and sequential turn signals give the F-350 a modern, aggressive face. Underbody lighting highlights the suspension hardware and lift underneath, and rock lights add accent glow around the running gear. Grille-integrated lighting and amber marker accents round out the show-presence palette for a truck that commands attention at night as much as in daylight. For the off-road and work path, a bumper-mounted LED light bar throws serious forward light for trail or job-site use. Ditch lights mounted at the A-pillars cast focused light to the sides for trail navigation. Fog lights and pod lights fill in the gaps for low-speed work in poor visibility. These are functional tools, and on a truck that hauls and works, they earn their place on their own merits.
On the exterior, fender flares are a natural fit for any F-350 running wider-than-stock tires: they extend coverage past the factory bodyline and catch the road debris that wider tires kick up. A front bumper swap is one of the most impactful visual changes on this platform, whether you go with a clean, low-profile replacement for the show build or a winch-capable steel bumper for the off-road build. Rear bumpers, nerf bars, and power steps round out the exterior for daily usability. Bed accessories are well-supported on this platform: tonneau covers, bed racks, and bed storage solutions keep the cargo area organized and protected. Grille replacements and hood accessories let you dial in the front-end look to match the lift and wheel stance. Inside, weatherproof floor liners and seat covers protect the interior on a truck that works as hard as it looks. Interior trim accents and storage solutions keep the cab organized for long hauls or job-site days.
Good: A leveling kit raises the front to eliminate factory rake and level the truck front-to-rear, with new hardware matched to the added height. Better: A 3-to-4-inch suspension lift with new shocks and geometry-correction hardware for a commanding stance and real tire clearance gains. Best: A full 6-to-8-inch suspension lift with new shocks, upper control arms, and full geometry correction for maximum ride height and the biggest tire the platform supports.
Good: A cold air intake for improved throttle response and induction character on any engine in the lineup. Better: Cold air intake paired with a DPF-back exhaust on the 6.4L diesel or a cat-back on the gas engines, plus intercooler and piping upgrades on the Power Stroke. Best: Full intake, exhaust, and intercooler combination with supporting drivetrain upgrades and a calibration tune to optimize the full bolt-on package.
Good: Fender flares to cover wider tires, nerf bars or running boards, and a tonneau cover for the bed. Better: Front and rear bumper upgrades, grille replacement, LED headlight and tail-light swap, and bed rack or storage system. Best: Full exterior package with a winch-capable front bumper, rocker protection, hood upgrade, underbody lighting, and a complete lighting overhaul front to rear.
Good: Weatherproof front and rear floor liners and seat covers for daily protection. Better: Full floor liner set, seat covers, interior trim accents, and bed storage solutions. Best: Complete interior protection package with upgraded floor carpet, custom seat covers, interior LED lighting, and organized storage throughout the cab.
Good: 20x12 -44 with 33x12.50R20 tires on stock suspension. Most of these bolt on clean, though some need minor trimming and a slight rub at full lock is common. Better: 20x12 -44 with 35x12.50R20 tires on a leveling kit. Most builders run minor plastic trimming at this setup, and rubbing at full lock is common. Best: 20x12 -44 with 37x13.50R20 tires on an 8-inch lift. This combo almost always bolts on clean and most builders report no rubbing.
Good: A clean, purposeful improvement over stock. The truck looks intentional and drives better without going all-in on the build. Better: Aggressive street presence with a stance that turns heads. A truck that hauls during the week and looks the part on the weekend. Best: Full show-truck intent. Maximum visual presence, built to be seen, the kind of build that stops people in the lot.
There is no single right starting point. Builders who want the biggest visual change fast usually start with wheels, tires, and a leveling kit together. Builders focused on capability start with a full suspension lift. Performance-first builders go intake and exhaust first. Our Gallery shows thousands of 2008 F-350 builds at every stage, so you can see what others on your exact truck have done and build from there.
Yes. Get pre-approved before you start building your cart so you know your budget going in. Pre-approval is fast and does not require a purchase to complete. Once you know what you are approved for, you can build out the full suspension, wheel and tire, and accessory package in one order and pay over time. Do not wait until checkout to figure out financing.
Absolutely. Our team handles both sides. On the fitment side, we can walk you through offset selection, tire sizing for your lift height, and what clears on a dually versus a single-rear-wheel setup. On the install side, we can talk through how mods stack, what hardware you need, the right sequence, and the common gotchas on the 6.4L Power Stroke and the gas engines. Call or reach out and we will get you sorted.
