A 1999 Ford F-350 leveling kit has to match more than the model year. Confirm 2WD or 4WD, the truck’s production date and its existing front suspension before ordering. The Rough Country 49800 kit discussed here is a 2-inch front mini-leaf kit for specified 4WD applications, and its manufacturer excludes trucks built before March 1, 1999.
For an eligible truck, it is one option to investigate with your installer. For an early-build 1999, a 2WD truck or a truck with modified springs, stop and get a configuration-specific recommendation. A broad “fits 1999–2004” marketplace heading does not resolve those differences.
Identify the truck before choosing the kit
- Confirm the drivetrain. Record whether it is 4×2 or 4×4. Do not select a kit using F-350 badges alone.
- Find the production date. Read the vehicle’s certification label and have the VIN available. If the label is unclear, ask Ford or the suspension manufacturer to identify the build before ordering.
- Record the configuration. Include engine, cab, pickup versus chassis cab, and single versus dual rear wheels. Ask the kit manufacturer to confirm any configuration not explicitly addressed.
- Photograph the current suspension. Note spring changes, added leaves, shackles, blocks, existing lift components and nonstandard shocks. A previous owner’s modifications can invalidate a stock-fitment assumption.
- Describe the goal. Reducing unloaded rake, clearing a particular tire and correcting a sagging front end are different jobs. Tell the installer which problem you are trying to solve.
Keep this information in one note with the kit’s part number. That gives a supplier something concrete to verify and makes it easier to spot a mistaken product substitution.

Rough Country 49800: 2-inch front mini-leaf leveling kit
Rough Country 49800, 2-Inch Front Mini-Leaf Kit for Specified 1999-2004 Super Duty 4WD, 1 Kit
As an Amazon Associate we earn from qualifying purchases.
The selected listing is part 49800, containing two front mini-leaf packs, four U-bolts and associated hardware. It is the leveling-hardware package, not a bundle of replacement shocks or a complete front-and-rear suspension system.
Required fit check: Rough Country’s current 49800 application page specifies F-250/F-350 Super Duty 4WD and explicitly excludes production dates before March 1, 1999. Do not assume the Amazon year range overrides that restriction.
The manufacturer’s installation instructions describe use with the factory two-leaf front spring pack. Existing add-a-leaves or overload arrangements require attention to those instructions and professional confirmation; do not simply stack this kit onto whatever is already installed.
Who should consider it: An owner whose truck satisfies all those requirements and whose suspension is serviceable. The decision should include installation, alignment and any necessary repairs, rather than comparing the parts price alone.
What to do if your truck is outside that application
Early-build 1999 4WD
Ask for a kit specifically confirmed for your production date. Send the supplier your suspension photographs and existing component details. “It worked on another 1999” is insufficient when the manufacturer publishes a date restriction. Do not drill, substitute hardware or mix parts to force a later-build kit to fit.
1999 2WD
Use a 2WD-specific application. ReadyLIFT’s installation-document directory separates its Super Duty 2WD and 4WD front-leveling systems, which is a useful reminder to obtain the correct instructions before buying. The 4WD mini-leaf kit above is not a recommendation for a 2WD truck.
2005-and-newer Super Duty kits
Do not treat these as interchangeable with a 1999 application. ReadyLIFT’s Super Duty fitment guide assigns separate kits to the 1999–2004 and 2005–2010 4WD trucks. A familiar model name and the same advertised lift height are not sufficient evidence of fit.
Measure stance and inspect wear first
Park on a level surface with the tires correctly inflated and record the truck’s normal load. Measure consistently from each wheel center to the corresponding fender edge, using the same reference points when you repeat the measurements. Record all four corners instead of judging the front from a photograph.
These measurements help describe the starting stance; they do not diagnose the suspension or guarantee a finished height. If one front corner sits unusually low, or the truck has damaged leaves, excessive steering play or unstable handling, have the underlying problem inspected before choosing a lift height.
Also consider the load you actually carry. An unloaded truck that looks level may have a different attitude with a trailer or equipment aboard. Ask the installer to assess the intended working configuration, not just the empty appearance. Adding a front leveling kit does not establish a higher payload or towing rating.
Use the truck’s applicable ratings and actual loaded weights. Ford’s explanation of vehicle weight ratings distinguishes gross vehicle and axle limits; a visual stance measurement cannot replace those checks.
Will larger tires fit?
There is no reliable answer based on “2-inch level” alone. Give the installer the exact tire model and size, wheel diameter and width, offset or backspacing, and whether the wheels are factory equipment. Clearance has to be checked while steering and through suspension movement.
Rough Country’s manual describes a 305/70R16 tire on a factory wheel as its design reference, while its product page presents other wheel-and-tire combinations. Treat those as application-specific references, not a promise that every tire with a similar nominal diameter clears your truck.
Before buying tires, request a fit check that considers the bumper, bodywork, suspension, brake hoses and full steering movement. A plan that depends on unapproved trimming or guessed wheel spacers needs to be resolved before installation. Avoid purchasing a second incompatible item to compensate for the first.
Installation and follow-up belong in the budget
Rough Country recommends a certified technician. Supporting a heavy truck and axle while working on spring retention hardware is not a suitable job for improvised stands or a jack alone. This guide is a buying checklist, not a substitute for the complete installation procedure and Ford service information.
For this kit, the manufacturer’s post-installation checklist includes fastener checks, steering and brake-hose clearance, a brake-system check, headlight adjustment and professional alignment. It also calls for retightening components after 500 miles and every 3,000 miles thereafter. Keep the instructions with the vehicle and confirm the applicable procedure with the installer.
Ask for a written estimate covering the kit, labor, alignment, worn components identified during inspection and any configuration-specific supporting parts. Keep the alignment printout and before-and-after measurements. If new vibration, pulling, rubbing or clunking appears, have it inspected rather than assuming it is normal for a leveled truck.
Buying decision
For a qualifying later-build 1999 4WD F-350, the Rough Country 49800 is a documented starting point. Confirm the spring arrangement and complete installed cost before purchasing. For early-build, 2WD or already-modified trucks, obtain written fitment confirmation for the exact configuration rather than buying from a generic year-range list.
