Hey guys! Thinking about giving your 2021 Ford F-150 STX a bit of a lift? A leveling kit is a fantastic way to not only improve the look of your truck but also enhance its off-road capabilities and overall stance. In this guide, we'll dive deep into everything you need to know about leveling kits for your F-150 STX, from why you might want one to how to choose the right kit and what to expect during the installation process. Let's get started!

Why Level Your 2021 Ford F-150 STX?

So, why should you even consider leveling your truck? From the factory, most trucks, including the Ford F-150 STX, come with a raked stance. This means the rear of the truck sits higher than the front. There are several reasons for this design choice by manufacturers. Primarily, it's to improve aerodynamics and fuel economy, and also to prevent the rear from sagging when you're hauling or towing heavy loads. However, this look isn't always the most appealing to everyone. Many truck owners prefer a more even, level look. This is where leveling kits come in handy.

Aesthetics: Let's be honest, the first reason most people consider a leveling kit is for the improved appearance. Leveling your F-150 STX gives it a more aggressive, balanced look. It eliminates that nose-down rake and makes your truck stand out from the crowd.

Larger Tires: Another significant advantage of leveling kits is that they create additional clearance for larger tires. Want to upgrade to some beefier, more aggressive tires? A leveling kit will provide the necessary space to do so without worrying about rubbing or clearance issues. This is particularly appealing if you plan on doing any off-roading.

Off-Road Performance: Speaking of off-roading, leveling kits can improve your truck's off-road capabilities by increasing ground clearance and improving approach angles. This means you'll be less likely to scrape the front end of your truck when tackling obstacles on the trail. Plus, with those larger tires you can now fit, you'll have even more traction and control.

Improved Visibility: Some drivers find that a leveled truck offers improved visibility. By raising the front of the truck, you get a better view of the road ahead, which can enhance your overall driving experience and safety.

Load Carrying: Although the main reason for the factory rake is to assist with load carrying, a leveling kit can still be used effectively if you often have a load in the bed of your truck. While a leveling kit may slightly reduce the maximum load your truck can handle without sagging, the impact is often minimal for everyday use. If you frequently haul heavy loads, you might consider other suspension upgrades in addition to a leveling kit, such as upgraded rear springs or air helper springs.

Choosing the Right Leveling Kit for Your F-150 STX

Okay, so you're convinced that a leveling kit is right for you. The next step is choosing the right kit for your 2021 Ford F-150 STX. With so many options on the market, it can be a bit overwhelming. Here's what you need to consider:

Type of Leveling Kit: There are primarily two types of leveling kits: strut spacers and coil spring spacers. Strut spacers are the most common and generally the most affordable option. They are installed on top of your existing struts and effectively extend their length, lifting the front of the truck. Coil spring spacers, on the other hand, are installed inside the coil springs. Both types achieve the same result, but strut spacers are typically easier to install.

Lift Height: Leveling kits typically provide anywhere from 1.5 to 2.5 inches of lift. The amount of lift you choose will depend on your personal preference and the size of tires you want to run. A 2-inch leveling kit is a popular choice as it provides a noticeable improvement in appearance without overly compromising ride quality or requiring additional modifications.

Material Quality: The material quality of the leveling kit is crucial for its durability and longevity. Look for kits made from high-quality steel or aluminum. Avoid kits made from cheap plastic or low-grade materials, as they may not hold up well over time, especially if you frequently off-road or drive on rough roads.

Brand Reputation: Stick with reputable brands that have a proven track record of producing high-quality leveling kits. Some popular brands include Rough Country, ICON Vehicle Dynamics, Bilstein, and Fox. Reading reviews and doing your research can help you identify reliable brands and avoid potential issues.

Installation: Consider the installation process when choosing a leveling kit. Some kits are easier to install than others, and some may require specialized tools or expertise. If you're planning on installing the kit yourself, choose one that comes with clear, detailed instructions and doesn't require any major modifications to your truck. Alternatively, you can have a professional mechanic install the kit for you.

Ride Quality: Keep in mind that leveling kits can slightly affect your truck's ride quality. While most leveling kits are designed to maintain a comfortable ride, some may make the ride a bit firmer or harsher, especially on rough roads. Reading reviews and talking to other F-150 owners can give you a better idea of what to expect in terms of ride quality.

Installation: What to Expect

So, you've chosen your leveling kit, and now it's time for installation. Whether you're tackling the job yourself or having a professional do it, here's what you can expect:

Preparation: Before you start, gather all the necessary tools and equipment. You'll typically need a jack, jack stands, wrenches, sockets, a torque wrench, and potentially a spring compressor (depending on the type of kit). Read the instructions carefully and familiarize yourself with the installation process.

Disassembly: The first step is to safely lift the front of your truck and remove the wheels. Then, you'll need to disconnect the sway bar links, brake lines, and any other components that may be attached to the struts. Next, carefully remove the struts from the truck.

Installation of the Leveling Kit: Depending on the type of kit you've chosen, you'll either install the strut spacers on top of the struts or the coil spring spacers inside the coil springs. Follow the instructions provided with the kit carefully. Make sure everything is properly aligned and securely tightened.

Reassembly: Once the leveling kit is installed, it's time to reassemble everything. Reinstall the struts, reconnect the sway bar links and brake lines, and reinstall the wheels. Make sure everything is properly torqued to the manufacturer's specifications.

Alignment: After installing a leveling kit, it's essential to get your truck's alignment checked and adjusted. Leveling kits can affect your truck's alignment, which can lead to premature tire wear and handling issues. A professional alignment will ensure that your truck drives straight and true.

Test Drive: Once everything is reassembled and aligned, take your truck for a test drive. Pay attention to how it handles and feels. Check for any unusual noises or vibrations. If you notice anything out of the ordinary, take it back to the shop or re-inspect your work to ensure everything is properly installed.

Things to Keep in Mind

Before you rush out and install a leveling kit on your 2021 Ford F-150 STX, here are a few additional things to keep in mind:

Warranty: Installing a leveling kit may affect your truck's warranty. Check with your Ford dealer or warranty provider to see if installing a leveling kit will void any part of your warranty. Some dealers are more lenient than others, but it's always best to check beforehand.

Ride Quality: As mentioned earlier, leveling kits can slightly affect your truck's ride quality. While most kits are designed to maintain a comfortable ride, some may make the ride a bit firmer or harsher. If ride quality is a major concern for you, choose a leveling kit that is specifically designed to maintain a smooth, comfortable ride.

Tire Size: When choosing a leveling kit, consider the size of tires you want to run. A leveling kit will provide additional clearance for larger tires, but you'll need to make sure that the tires you choose will fit without rubbing or causing other issues. Consult with a tire shop or online resources to determine the maximum tire size that will fit on your truck with your chosen leveling kit.

Professional Installation: If you're not comfortable installing a leveling kit yourself, it's always best to have a professional do it. A professional mechanic will have the necessary tools, expertise, and experience to install the kit correctly and safely. This can give you peace of mind knowing that the job is done right and that your truck is safe to drive.

Conclusion

Leveling kits are an excellent way to enhance the look and performance of your 2021 Ford F-150 STX. They provide a more aggressive, balanced appearance, allow for larger tires, and can improve off-road capabilities. By choosing the right leveling kit and following the installation instructions carefully, you can transform your truck into the envy of the neighborhood. Just remember to consider factors such as ride quality, warranty, and tire size before making your decision. Happy leveling!
