Aldan American coilover kits provide adjustable ride height and the ability to change spring rates to fine-tune handling, combined with a lighter assembly than OEM, reducing unsprung weight. Our coilover kits are manufactured in the U.S. from lightweight, high-strength 6061-T6 billet aluminum. Aluminum is chosen over steel for several reasons, including lightness and its far better ability to shed the heat generated by the shock’s movements than steel.

The accompanying coilover springs are CNC-formed from high-tensile, cold-wound steel to deliver consistent performance. They are then immersed in a high gloss black finish formulated to help preserve the life and longevity of the springs. Our coilover kits are available in factory pre-set (nonadjustable), single-adjustable (rebound) and double-adjustable (rebound and compression) configurations. Shock ends can be ordered with polyurethane bushings for a more comfortable ride or with spherical bearings for more precise control.

All Aldan American coilover kits have been designed and developed incorporating our more than 40 years of experience in muscle car suspension. They are available in almost any dimension for your street rod, hot rod, classic or modern muscle car and truck, and racing or custom chassis vehicle.

Frequently Asked Questions:

What is a coilover kit?

A coilover kit is a suspension system that consists of a shock absorber and coil spring assembly that is designed to replace the factory suspension components on a vehicle. 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 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. They can be adjusted to 2” ride height, and the spring rate and damping force are also 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 coilover kit replaces both the struts and springs in a vehicle’s suspension system. A coilover kit consists of a shock absorber and coil spring assembly that is designed to replace the factory suspension 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.

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.
