Beyond aesthetics, leveling kits serve practical purposes, such as improving ground clearance and reducing the risk of front-end bottoming out when driving over rough terrain. They can also enhance stability when towing by keeping the vehicle level. However, not all leveling kits are the same—choosing the wrong one can negatively impact ride quality, handling, and suspension longevity. Understanding the different types of leveling kits will help you make an informed decision that best suits your truck and driving needs.
Types of Leveling Kits
1. Strut Extension Leveling Kits
Strut extension leveling kits, also known as strut spacers, are one of the most common and cost-effective ways to raise the front of a truck. These kits consist of metal or polyurethane spacers that are installed on top of the factory struts, providing lift without modifying the internal components of the suspension. This type of kit is designed for trucks and SUVs equipped with coil-over strut suspension systems, making it a great option for many modern vehicles. Since strut spacers do not alter the compression or damping of the strut, they help retain the factory ride quality while still achieving a more balanced look.
One of the biggest advantages of strut extension kits is their ease of installation. Unlike other suspension modifications, they typically do not require cutting, welding, or major disassembly of the suspension system. This makes them a popular choice for DIY enthusiasts looking for a quick and effective solution. However, while these kits provide a budget-friendly way to level a truck, they may slightly alter the truck’s suspension geometry, which can lead to minor changes in handling and alignment. To ensure the best performance and longevity of your suspension, it’s recommended to have a professional alignment done after installation.
2. Coil Spring Spacer Leveling Kits
Coil spring spacer kits work by inserting spacers either above or below the front coil springs, depending on the truck’s suspension design. This type of leveling kit is specifically used for vehicles that have coil spring front suspension instead of struts. The spacers are typically made from polyurethane, aluminum, or steel, with polyurethane offering a more affordable option and metal spacers providing enhanced durability for off-road applications. By slightly compressing or shifting the coil springs, these spacers allow the front of the truck to sit higher, eliminating the factory rake and improving ground clearance.
One of the main benefits of coil spring spacers is that they provide a simple and cost-effective lift without replacing the entire suspension system. They are a great option for truck owners who want a budget-friendly way to level their ride while still using stock shocks and control arms. However, if the spacers are too thick, they may cause coil bind—a situation where the coils become overly compressed, reducing suspension travel and leading to a harsher ride. Additionally, just like with strut extension kits, an alignment is necessary after installation to ensure proper handling and prevent uneven tire wear.
3. Torsion Key Leveling Kits
Torsion key leveling kits are specifically designed for trucks and SUVs with torsion bar suspension systems, which are commonly found on Chevrolet, GMC, and Dodge Ram models. These kits include reindexed torsion keys that replace the factory-installed ones, allowing the front end to be raised by adjusting the tension in the torsion bars. Unlike strut or coil spring leveling kits, which physically add height through spacers, torsion key kits work by modifying the way the existing suspension components support the vehicle’s weight. This allows for a precise lift without excessive stress on other parts of the suspension.
One of the key advantages of torsion key kits is that they offer adjustability, meaning truck owners can fine-tune the height to their preference. However, increasing the tension in the torsion bars too much can lead to a stiffer ride and increased wear on ball joints, control arms, and CV axles. To avoid premature wear and poor handling, it’s important to use high-quality aftermarket torsion keys instead of simply cranking up the factory ones. Additionally, pairing the kit with aftermarket shocks designed for lifted applications can help maintain ride comfort and improve suspension performance.
4. Leaf Spring Shackle Leveling Kits
Leaf spring shackle leveling kits are primarily used on older trucks with leaf spring front suspension, though they are less common in modern vehicles. This type of kit works by replacing the stock leaf spring shackles with extended ones, which slightly raises the front end of the truck. It’s a relatively simple modification that does not require significant changes to the suspension system, making it a straightforward and inexpensive solution for achieving a level stance. However, since modern trucks typically use strut or torsion bar suspensions, leaf spring shackles are not as widely used today.
While leaf spring shackle kits provide a modest lift, they do have some drawbacks. Extended shackles can alter the suspension’s geometry, potentially leading to changes in ride quality and handling. In some cases, they may also reduce the amount of flex in the suspension, affecting off-road performance. Additionally, since these kits are not as commonly available for newer trucks, finding a high-quality, well-engineered set can be challenging. If your truck still uses leaf spring suspension and you’re considering a shackle leveling kit, it’s best to consult with a professional mechanic to ensure proper installation and compatibility.
5. Adjustable Coilovers for Leveling
For truck owners who want the best of both worlds—leveling and performance—adjustable coilover suspension systems are a premium alternative to traditional leveling kits. Unlike spacer or torsion key kits, which modify the existing suspension components, adjustable coilovers completely replace the factory struts and springs, allowing for precise height adjustment. This makes them the ideal choice for those who frequently drive off-road or require a more customized suspension setup. Additionally, adjustable coilovers offer superior ride quality, improved handling, and better weight distribution, making them a top choice for high-performance trucks.
The biggest downside of adjustable coilovers is cost—they are significantly more expensive than standard leveling kits. However, for those who demand the best suspension performance and customization, they are well worth the investment. Another factor to consider is that installation is more complex and typically requires professional expertise. Unlike simpler leveling kits, which can often be installed in a few hours, adjustable coilovers require precise tuning and alignment to get the most out of the system. While they may not be necessary for every truck owner, those looking for top-tier ride quality and suspension control will find that adjustable coilovers are the ultimate choice for leveling their vehicle.
How to Choose the Right Leveling Kit
Selecting the right leveling kit depends on factors such as truck model, intended use, budget, and installation complexity. While some kits are easy to install with basic tools, others require professional expertise to ensure proper alignment and safety. Choosing a reputable brand is crucial to avoid performance issues or premature wear on suspension components.
