Firstly, consider the truck’s purpose. If your truck is primarily used for utility purposes, like towing or off-roading, a significant drop in height could affect its performance. However, a more pronounced drop might be suitable if you’re leaning more toward an aesthetic enhancement.

Reflect on the look and style you’re aiming for. Do you want a subtle change or a pronounced transformation? This decision will directly influence your chosen lowering method, with each offering a different degree of height reduction.

The final dimension to consider is your budget. The extent of the lowering project can have a notable impact on costs, including parts, labor, and potential adjustments required post-installation.

3. Choosing the Right Lowering Method

With a firm understanding of your truck’s current specifications and a clear vision of the desired outcome, you’re well-equipped to select an appropriate lowering method. There are four popular options: Coil Springs, Drop Spindles, Control Arms, and Air Springs.

Coil Springs are straightforward – they’re essentially the springs bolstering your suspension. Replacing your existing springs with shorter and stiffer ones can lower your truck. This method is quite popular due to its cost-effectiveness and simplicity.

Drop Spindles introduce a small bracket that permits your wheel to nestle farther up into the fender well. This relocation leads to a lower truck stance. However, watch out for wheel clearance issues with this method. It’s essential to note that not all drop spindles are suitable for 4×4 trucks.

Control Arms serve as a replacement for the factory wishbones at the front of your truck. The new arm has a deeper coil spring pocket, facilitating a two to three-inch drop. Ensure the control arm spring pocket doesn’t dip below the scrub line if you’re planning on using low-profile tires.

Air Springs, or airbags, offer considerable flexibility. They can drop the truck’s stance significantly when deflated and replace factory coil springs in the front and back. For drastic lowering, professional customization is recommended.

Each method comes with its pros and cons, and your choice will largely depend on your specific truck, the desired degree of lowering, and your budget.

4. Purchase the Appropriate Lowering Kit

Having decided on a suitable lowering method, your next step is to purchase a corresponding lowering kit. Lowering kits are generally comprehensive, providing all the essential components needed for the lowering process. The contents of the kit will differ based on the method you’ve selected.

The kit would include shorter and stiffer springs if you chose Coil Springs. Control Arms will consist of the arms with the deeper spring pocket. An Air Springs kit would contain airbags that can be retrofitted into your truck’s suspension system.

Ensure the kit is compatible with your truck model. For instance, a GMC Sierra owner would need equipment specifically designed for this model. It’s essential to research thoroughly before making a purchase.

It’s recommended to purchase kits from reputable manufacturers or suppliers to ensure the quality and reliability of components. At the same time, price is a factor to consider; prioritize quality and compatibility to avoid future complications and ensure your lowered truck’s longevity and performance.

5. Remove the Existing Suspension Lift

Before you dive into installing your new lowering kit, it’s important to address the existing suspension lift on your truck. Since suspension lifts and lift kits are designed to raise the vehicle’s height, keeping them intact contradicts your lowering goal. Thus, they must be removed prior to the lowering process.

Technician While Removing Suspension Lift

The first aspect of this step is understanding the type of lift kit previously installed in your truck. This might be a body lift or suspension lift kit, and each requires a different removal procedure.

Be aware that removing a lift kit isn’t just about uninstalling specific components. It also involves reverting to the original parts that were replaced or altered during the lift kit installation. This might include shocks, struts, control arms, springs, and other suspension components, which need to be returned to their stock state.

This step can be intricate and time-consuming, requiring mechanical expertise. It’s crucial to follow all safety procedures and use the appropriate tools to prevent damaging your truck’s components or causing personal injury. Don’t rush this process – careful, accurate work here lays the foundation for the successful lowering of your truck.

6. Install the Lowering Kit

With the existing suspension lift successfully removed, you’re ready to begin installing your lowering kit. This step transforms your truck, bringing it closer to the ground and enhancing its aesthetic appeal and, potentially, aerodynamics.

The installation process depends entirely on the type of lowering kit you’ve chosen. Each kit has its own instructions that you should follow meticulously. For instance, if you opted for a Coil Springs kit, you’ll be replacing your existing springs with the shorter ones from the kit.

If you choose a Control Arms kit, you’ll replace the front wishbones with the new control arms. Air Springs kits involve the installation of airbags into the suspension system.

Remember, the process isn’t complete as soon as the new components are installed. You’ll need to adjust and fine-tune them to ensure they’re working in harmony with the rest of the truck’s system.

7. Check for Wheel Clearance

After successfully installing your lowering kit, checking for wheel clearance is crucial. This step assesses the space available for the wheel to move without hindrance from the truck’s body or suspension components.

Driver Checking The Wheel Clearance

Maintaining appropriate wheel clearance is vital for preserving the functionality of your 4×4 wheel drive’s functionality and ensuring your lowered truck’s safety and performance. Depending on your chosen lowering method, the wheel might sit farther up into the fender well.

This adjustment might reduce the available wheel clearance. It’s essential to confirm that the wheel has enough room to turn freely and function effectively in a range of driving conditions, from daily commuting to off-roading.

Moreover, you must also ensure that the tires do not come into contact with the truck’s body or suspension components during movement. This can cause tire wear and damage to the truck’s bodywork, leading to additional costs and safety risks.

Bear in mind that wheel clearance is not a static measurement, as various factors can impact it, including tire size, wheel size, suspension travel, and the truck’s load. Ensure that you’re factoring in these variables when checking wheel clearance on your lowered truck.

8. Test Drive and Adjust as Necessary

With the lowering kit installed and wheel clearance checked, you’re nearing the finish line. But before celebrating, one crucial step remains the test drive. This step serves as your first real-world assessment of the changes made to the truck.

The test drive allows you to see how your truck behaves on the road with its new lowered stance. Observing the ride quality, handling characteristics, and overall performance is essential. Pay attention to how the truck responds to acceleration, braking, cornering, and driving over bumps.

This is also an opportunity to identify any potential issues that might not be apparent when the truck is stationary. Listen for unusual sounds and feel for irregular vibrations that could indicate problems. If anything seems amiss, don’t hesitate to make necessary adjustments or consult with a professional.

Remember, the goal of this entire process is to achieve a lowered truck that not only looks appealing but also delivers performance, safety, and reliability.

This test drive is your first chance to assess whether you’ve achieved that goal. Take the time to conduct a thorough test and make any necessary adjustments to ensure your truck is in peak condition.
