  • Universal Coilover Kits: American-Built Performance Suspension 

    Upgrade your vehicle’s handling and stance with American-made universal coilover kits from Aldan American. Since 1981, we’ve been crafting high-performance coilover suspension kits right here in the USA, delivering results for modern and classic trucks, late-model vehicles, and classic cars.

    Universal Coilover kits are designed for custom chassis, IFS, IRS, 4-Link suspensions and more. If you have a ride height or coilover extended length, the team at Aldan American can help you determine the perfect universal coilovers you’ll need for your car or truck build.

    Engineering at Its Finest 

    Every coilover kit starts with aerospace-grade 6061-T6 billet aluminum, chosen specifically for its exceptional strength and heat dissipation. Compared to steel components, our aluminum construction cuts unsprung weight while managing the heat generated during hard driving. The result? Coilovers that perform consistently, mile after mile.

    Real Adjustability for True Performance

    Our adjustable coilover kit options give you command over your vehicle’s performance:

    • Factory Pre-Set Systems: Built for daily drivers who want reliable, consistent performance without adjustment needed. These coilover suspension kits deliver enhanced handling straight from the box.
    • Single-Adjustable Systems: These allow you to fine tune your rebound or compression settings for firmer or softer shock damping. These systems put you in control of your vehicle’s overall ride quality.
    • Double-Adjustable Systems: These allow you to fine tune your rebound and compression settings independently. These are ideal for hard driving, racing, and high performance vehicle suspensions.  

    American-Built Springs

    Aldan American coilover springs are made right here in the USA and come with a lifetime warranty. Our coilover springs offer superior overall performance consistency compared to OEM and overseas variants that are on the market today.

    Frequently Asked Questions:

    What is a coilover kit?

    A universal coilover suspension kit is a complete suspension system that consists of a shock absorber and coil spring assembly designed to replace factory suspension components. Universal coilover kits are typically used for performance or racing applications, as they offer greater adjustability, customization, and improved handling compared to traditional suspension systems.

    Our coilover kits are sold as a complete package that includes all necessary components for installation, such as the shock absorber, coil spring, shock mounts, and hardware. Some of our coilover kits also include additional components, such as control arms, for even greater adjustability and performance.

    Our universal coilover kits are available for a wide variety of vehicles and are designed for an OEM like fitment. We offer single and double adjustable coilover kits to fit different types of driving conditions and performance requirements. The spring rate and damping force can be adjusted to fine-tune the suspension to the specific vehicle and driving conditions.

    Does a coilover kit replace the struts and springs?

    Yes, Aldan American’s universal adjustable coilover kit replaces both the struts and springs in your vehicle’s suspension system. Our universal coilover suspension kits combine the shock absorber and spring into a fully tunable unit that delivers superior performance over factory components.

    Traditional strut systems combine the shock absorber and spring into a single unit, whereas coilover kits have a separate shock absorber and coil spring that can be adjusted independently. The coil spring sits over the shock absorber, and both are mounted to the vehicle’s chassis and suspension arms.

    By replacing both the struts and springs with a coilover kit, the suspension system can be customized and fine-tuned for improved handling and performance. Coilover kits are often used by racing enthusiasts or performance drivers who demand the highest level of adjustability and performance from their suspension system.

    It’s important to note that coilover kits may not be suitable for all types of vehicles or driving conditions. They are designed primarily for performance applications, and may require additional modifications or maintenance to achieve optimal performance and safety. It’s also recommended to have a professional install and align the coilover kit to ensure proper installation and optimal performance.

    What should I look for when choosing a coilover kit for my vehicle?

    Compatibility: Make sure that the coilover kit you choose is compatible with your vehicle’s make, model, and year. Coilover kits are often designed for specific applications, so it’s important to choose one that is designed to fit your vehicle.

    Quality: Look for a high-quality coilover kit that is made from durable materials and has a reputation for reliability. In the case of Aldan American coilover kits our parts are rebuildable extending the life of your investment by allowing you to perform individual part maintenance on your suspension system. Avoid cheap, low-quality coilover kits, or kits that aren’t rebuildable and that may wear out quickly or fail to provide adequate performance over time.

    Adjustability: Consider the adjustability of the coilover kit. Look for a kit that allows you to adjust the ride height, spring rate, and damping force to fine-tune the suspension to your driving needs and preferences. Aldan American’s coilover kit is fully adjustable, allowing you to lower your ride height up to 2”.

    Performance: Choose a coilover kit that is designed to provide the performance benefits you are looking for, whether that’s improved handling, better cornering, or a smoother ride. Look for a kit that is designed for your specific type of driving, such as racing or daily driving.

    Price: Coilover kits can range in price from a few hundred dollars to several thousand dollars. Consider your budget and choose a kit that provides the performance and adjustability you need at a price you can afford.

    Manufacturer reputation: Choose a coilover kit from a reputable manufacturer with a proven track record of producing high-quality suspension components and one that can provide you direct support in the event you need maintenance or installation assistance, you’re looking for an established business with positive reviews and feedback from other customers to get an idea of the quality and performance of the kit. Aldan American for example has a 40 year history of excellence in suspension part engineering coupled with a dedication to providing personal service and assistance to each customer for every part sold.

    By considering these factors, you can choose a coilover kit that is designed to fit your vehicle, provide the performance benefits you need, and offer the adjustability and quality you are looking for. It’s always recommended to have a professional install and align the coilover kit to ensure proper installation and optimal performance.

    What are the benefits of installing a coilover kit on my vehicle?

    Improved handling and performance: Coilover kits can improve your vehicle’s handling by allowing you to adjust the suspension height, stiffness, and damping to suit your driving style and road conditions. This can provide better stability, cornering, and traction.

    Enhanced aesthetics: Coilover kits can lower your vehicle’s ride height, which can give it a more aggressive and sporty look.

    Increased durability: Coilover kits are often made of high-quality materials and are designed to withstand the rigors of high-performance driving, which can result in increased durability and longevity.

    Customizable ride comfort: Coilover kits allow you to adjust the suspension to your desired level of stiffness or softness, which can provide a more comfortable ride or a more track-oriented setup depending on your preferences.

    Increased resale value: Upgrading your vehicle with a coilover kit can increase its resale value, as it shows that you have invested in improving the performance and aesthetics of the vehicle. Overall, installing a coilover kit on your vehicle can be a great way to improve its handling, performance, and appearance while also providing customizable options for your driving preferences.
