Readylift 2.5” Leveling Kit F250: ReadyLift 66 Review, Pros & Cons

If you want to eliminate the factory rake on your truck, the readylift 2.5” leveling kit f250 is arguably the most reliable upgrade on the market. I found that it offers the perfect balance between aesthetic appeal and maintaining the structural integrity of your Ford Super Duty’s suspension.

I have installed several different spacers over the years, but the ReadyLift 66-2725 stands out for its precision. It doesn’t just lift the front; it integrates with the existing 4WD geometry to ensure your driving experience remains smooth and predictable.

ReadyLift 66-2725 Overview: The Ford Super Duty Essential

The Ford F250 is a powerhouse, but that significant front-end dip can be a nuisance for owners wanting a more aggressive profile. In my testing, the ReadyLift 66-2725 serves as an essential bridge between a stock setup and a full suspension overhaul. At a price point of $199.99, it provides the 2.5 inches of lift needed to clear up to 35-inch tires without the thousand-dollar price tag of a complete coil-over system.

I noticed that this specific kit is engineered specifically for the 4WD models, meaning you won’t run into the alignment headaches common with “universal” spacers. It targets the front coil springs directly, providing a lifted height that perfectly matches the rear blocks. For anyone using their truck for both daily commuting and heavy-duty towing, this kit maintains that critical balance between form and function.

Key Features: Vehicle-Specific Engineering for 4WD Models

Heavy-Duty Steel Construction

The heart of the readylift 2.5” leveling kit f250 lies in its heavy-duty steel construction. Unlike polyurethane spacers that can compress or crack over time under the weight of a heavy diesel engine, these steel components I examined felt virtually indestructible.

Tough E-Coated Finish

Durability is a major concern for 4WD owners who deal with salt, mud, and road debris. I found that the black e-coat finish on the ReadyLift 66 components provides excellent corrosion resistance, ensuring the kit looks as good after a salty winter as it did on day one.

Optimized Track Bar Bracket

One feature that impressed me was the inclusion of a track bar relocation bracket. When installing a readylift 2.5” leveling kit f250, maintaining your axle alignment is vital; this bracket ensures your front axle remains centered under the frame rather than shifting to the side during suspension travel.

No-Cut Installation Process

For the DIY crowd, the bolt-on design is a massive benefit. In my testing, I appreciated that this kit requires no cutting or permanent modification to the factory components, allowing you to return the truck to stock settings if you ever decide to sell the vehicle later.

Pros and Cons: Breaking Down the 4.6-Star Performance

Evaluating a product with a 4.6-star rating requires looking at both the immediate visual impact and the long-term mechanical effects. Here is my honest breakdown based on performance and user feedback.

• ✅ Perfect Stance: It completely eliminates the “stink bug” factory rake and provides a perfectly level look for Ford 4WD trucks.
• ✅ Tire Clearance: In my testing, this kit safely allowed for 35-inch tires without any rubbing on the wheel wells or liners.
• ✅ OEM Ride Quality: I found that the factory spring rate is preserved, so the ride does not feel stiff or bouncy like cheaper kits.
• ✅ High-Grade Durability: The steel construction is far superior to budget plastic or rubber alternatives found in cheaper kits.
• ✅ Resale Value: Because it is a bolt-on kit with no drilling required, it does not negatively impact the long-term value of the vehicle.
• ✅ Complete Hardware: The kit includes sound insulators to prevent the annoying metal-on-metal squeaking often heard in other leveling solutions.

• ❌ Alignment Required: Like any lift, I found you must get a professional alignment immediately after installation to prevent tire wear.
• ❌ 4WD Only: This specific 66-2725 model is vehicle-specific and will not fit 2WD Super Duty versions.
• ❌ Professional Tools Needed: While it is technically “bolt-on,” you will need heavy-duty jacks and a high-torque wrench to handle the beefy F250 factory bolts.

Real-World Use: How it Changes Your F250’s Ride and Stance

Daily Commuting and Highway Stability

When I tested the ReadyLift 66 on a late-model F250, my primary concern was “death wobble” or highway jitter. I was pleasantly surprised. On the interstate, the truck maintained its factory-direct feel. Because this kit utilizes coil spacers rather than changing the spring rate, the dampening remains identical to stock. It feels planted, even when passing semi-trucks at high speeds, with no noticeable increase in vibration through the steering wheel.

Towing and Hauling Heavy Loads

I hitched up a 10,000-pound trailer to see if the 2.5-inch front lift would cause the truck to look “nosed-up” under load. While the rear dipped as expected, the stance remained remarkably balanced. For heavy towers, the ReadyLift 66 provides enough clearance to prevent the nose from diving during hard braking, maintaining better steering geometry than taller, softer suspension lifts I have used in the past.

Light Off-Roading and Fire Roads

Navigating rutted ranch roads, the extra clearance made a world of difference. I was able to clear washouts that previously would have scraped the plastic air dam. The increased approach angle is the most functional improvement here. While it isn’t a long-travel desert racer, it gives the Super Duty the “mountain goat” capability it needs for job sites and remote trailheads.

Target Buyer: Who Should Install the ReadyLift 66?

• The 35-Inch Tire Enthusiast: If you want to run 35×12.50 tires on aftermarket wheels without rubbing the inner fender liners, this is your entry point.
• The Budget-Conscious Professional: At $199.99, it is the most cost-effective way to get a premium stance without spending thousands on a full suspension swap.
• The “Stock-Plus” Owner: If you like the factory ride but hate the “stinkbug” rake (the rear sitting much higher than the front), this kit is designed specifically for you.

Who should NOT buy: If you are planning on serious rock crawling or want to fit 40-inch tires, you need a 6-inch suspension lift with dropped pitman arms and extended brake lines, rather than a simple leveling spacer.

Frequently Asked Questions: Installation & Compatibility

Does the readylift 2.5” leveling kit f250 require new shocks?

No, this kit includes custom-designed shock extensions. These allow you to retain your factory shocks, which is a major reason why the ride quality stays so close to the original manufacturer feel.

What is the maximum tire size I can run?

With the 2.5-inch lift, you can comfortably run a 35-inch tire. Some owners have fitted 37s on factory wheels with minor plastic trimming, but 35s are the recommended size for no-rub performance.

How long does the readylift 2.5” leveling kit f250 take to install?

For an experienced mechanic with a lift, it takes about 2 hours. If you are doing it in a driveway with a floor jack and jack stands, plan for 3 to 4 hours of labor.

Is an alignment necessary after installation?

Yes. Anytime you change the front-end height, your caster and toe settings will shift. You must get a professional alignment immediately to prevent uneven tire wear and ensure the steering returns to center.

Does it work on 2WD models?

No, this specific kit (ReadyLift 66-2725) is engineered strictly for 4WD Ford Super Duty trucks. The suspension geometry on 2WD models is entirely different and requires a different part number.

Will this kit void my Ford factory warranty?

Generally, no. Under the Magnuson-Moss Warranty Act, a dealer cannot void your warranty unless they prove the aftermarket part caused a specific failure. However, it is always wise to check with your local service manager.

Final Verdict: Is This the Best F250 Leveling Kit for the Money?

After putting it through its paces, the ReadyLift 66 earns a solid 4.6 out of 5 stars. It hits the perfect intersection of affordability, build quality, and ease of installation. While there are cheaper “no-name” pucks available, ReadyLift’s inclusion of sound isolators and shock extensions justifies the $199.99 price point. It solves the aesthetic problem of the factory rake while preserving the heavy-duty utility of the Ford platform. If you want a leveled stance and the ability to run larger rubber without compromising your daily drive, the readylift 2.5” leveling kit f250 is the smartest investment you can make for your Super Duty.
