Car coilovers are suspension components that combine a shock absorber and coil spring in one unit, replacing the factory shock. They improve handling and performance by reducing body roll and allowing adjustment of ride height, damping force, and spring rate. This lets drivers fine-tune suspension to match their driving style and road or track conditions. Coilovers enhance stability, traction, and vehicle appearance, but they require proper installation and adjustment for optimal safety and performance.

Universal Coilover Shocks – Adjustable Coilovers
Build the suspension your vehicle deserves with American-made universal coilovers from Aldan American. Since 1981, we’ve been engineering premium coilover shocks that deliver superior performance for modern trucks, late-model vehicles, and classic cars.
Aerospace-Grade Aluminum For Performance
Every set of universal coilover shocks starts with aerospace-grade 6061-T6 billet aluminum, chosen specifically for its exceptional strength and heat dissipation properties. Unlike steel components, our aluminum construction dramatically reduces weight while managing heat generated during performance driving. The result? Coilover shocks that deliver consistent performance mile after mile.
Coilovers That Adjust To Your Driving Style
Our universal adjustable coilovers give you complete control over your vehicle’s performance:
Factory Pre-Set Systems: Engineered for daily drivers who want reliable, consistent performance without adjustment needed. These coilover shocks deliver enhanced handling straight from the box.
Single-Adjustable Systems: Control your rebound or compression rates for the exact balance of performance and comfort you want. These universal coilovers put you in command of your vehicle’s handling characteristics.
Double-Adjustable Systems: Full control over both rebound and compression for serious performance demands. When your driving takes you from street to track, our universal coilover shocks give you the adjustability real drivers demand.

Coilover Shock Frequently Asked Questions
What do coilovers do?
How long do coilovers last?
Coilovers generally last between 50,000 and 75,000 miles, depending on driving style, road conditions, and maintenance. High-quality coilovers that are properly installed and maintained can offer long-lasting performance and durability.
Are Aldan American’s coilovers universal?
Yes. Our universal coilovers are built to fit a wide range of vehicles and custom chassis setups, regardless of make or model. With modular mounts, bearings, and bushings, they offer flexibility and customization. The threaded shock body also allows adjustment of ride height, damping force, and spring rate to match different vehicle setups and driving conditions.
Are Aldan American coilovers adjustable?
Yes. Aldan American coilovers are fully adjustable. You can lower your ride height up to 2” by adjusting the spring perch on the threaded shock body. They also allow for damping adjustment to control compression and rebound, as well as spring rate adjustment to fine-tune the suspension for different vehicle weights or driving uses.
How long does it take to install coilovers?
Install time depends on the vehicle and your experience, but for someone with moderate mechanical skills, it usually takes 4 to 8 hours. Complexity of the setup and specific make/model can affect total install time.
