1999-2003 Ford F250/F350 Performance Parts and Accessories

With stock suspension, the largest tire size that generally fits is 33 inches on 16- or 17-inch wheels. If you’re running 35-inch tires, you will likely need a small lift or some trimming to avoid rubbing, especially on 4WD models.

The 7.3L Powerstroke Turbo Diesel engine in this generation is known for exceptional reliability, often considered one of the most durable diesel engines Ford has ever produced. The 4-speed automatic and 6-speed manual transmissions are also considered reliable, although regular maintenance is crucial to longevity.

Fuel economy for the 7.3L Powerstroke is typically between 12-18 MPG, with lighter loads and highway driving producing the best results. Towing and city driving can bring fuel economy closer to the lower end of that range.

There are numerous lift kit options available, from 2-inch leveling kits to 8-inch suspension lifts. Popular brands like BDS, Rough Country, and ICON offer kits that improve ground clearance and allow for larger tires.

The 7.3L Powerstroke Turbo Diesel in the 1999-2003 models produces 275 horsepower and 525 lb-ft of torque, which was impressive for its time and still holds up well for towing and hauling today.

The 7.3L Powerstroke is generally regarded as bulletproof, but some common issues include injector failures, HPOP (high-pressure oil pump) issues, and valve cover gasket failures. These problems are typically manageable with regular maintenance.

The 7.3L Powerstroke is responsive to performance upgrades. With diesel tuners, exhaust upgrades, and cold air intakes, owners can see gains of 75-100 horsepower. Many enthusiasts also upgrade to larger turbochargers and injectors for even more power.

The F-350 can tow up to 13,900 pounds with a gooseneck or fifth-wheel hitch, while the F-250 maxes out around 12,500 pounds with the same configuration.

With the FX4 Off-Road Package, which includes off-road shocks and skid plates, the 7.3L Powerstroke trucks are capable off-road. Many owners enhance off-road performance by adding lift kits, off-road tires, and upgrading to locking differentials.

The F-350 has a maximum payload capacity of around 5,500 pounds, while the F-250 can carry up to 3,800 pounds, depending on the equipment and configuration.
