Eibach suspension kits lower your truck's ride height and reduce body roll during turns
Eibach makes lowering springs and coilover kits designed to drop the front and rear of your truck closer to the ground. The springs are stiffer than factory springs, which means your truck sits lower and leans less when you turn. Eibach is a German suspension manufacturer that has been making performance springs since 1951, and their truck kits are sold through aftermarket retailers and some dealerships.
The main reason people install Eibach kits is appearance — a lowered truck looks more aggressive and sits flush with custom wheels. A secondary reason is handling: the stiffer springs reduce the amount your body rocks side to side in corners, which some drivers prefer. Eibach kits do not improve towing capacity or load-carrying ability; in fact, they can reduce ground clearance and may affect how your truck handles when fully loaded.
Key Takeaways
- Eibach suspension kits consist of lowering springs that drop your truck's height by 1 to 2 inches, depending on the model and kit type.
- Installation requires removing your wheels, unbolting the factory springs, and installing the Eibach springs in their place — a job that typically takes 2 to 4 hours per axle at a shop.
- Lowering springs change how your truck rides: the ride becomes firmer, and the truck may sit lower than the factory suspension can handle over rough terrain.
- Eibach offers different kits for different truck models; you must choose the kit built for your specific year, make, and model to may support proper fitment.
- Lowering your truck may affect your warranty, change your alignment settings, and reduce ground clearance, which can cause scraping on steep driveways or unpaved roads.
How Eibach suspension kits differ from factory springs
Factory springs on trucks are engineered to support the truck's weight, passengers, and some cargo while maintaining a comfortable ride on highways. They are relatively soft and allow the truck body to move up and down as the wheels go over bumps. Eibach lowering springs are much stiffer — they compress less under the same weight, which keeps the truck body lower and more level.
The trade-off is that a stiffer spring transfers more of the road's bumps directly to the frame and cabin. You will feel potholes and rough pavement more sharply than you do in a stock truck. Eibach kits also sit your truck lower, which reduces the distance between the undercarriage and the ground. This means you have less clearance for speed bumps, steep driveways, and unpaved roads.
What happens during installation
Installing an Eibach kit requires removing the wheels, unbolting the factory springs from the suspension, and bolting the new springs in place. On most trucks, this means working on both the front and rear axles. The job typically takes 2 to 4 hours per axle at a professional shop, though the exact time depends on whether your truck has rust, whether the bolts are stuck, and how accessible the springs are on your model.
After installation, your truck's alignment will be off — the angles of the wheels relative to the frame will no longer match the factory settings. You should have a shop perform a four-wheel alignment after the kit is installed. This costs between $100 and $200 and ensures your tires wear evenly and your truck handles predictably.
Eibach kit options for different truck models
Eibach makes kits for popular truck models including the Ford F-150, Chevrolet Silverado, GMC Sierra, Dodge Ram, and Toyota Tacoma. Each kit is built for a specific generation and model year. A kit for a 2019 F-150 will not fit a 2015 F-150, so you must verify your truck's year, generation, and cab style before ordering.
Eibach offers different spring rates (stiffness levels) within their truck line. A Pro-Kit is their entry-level lowering spring, while a Sport-Line kit is stiffer and lowers the truck more. Some kits are sold as springs only; others are sold as part of a coilover system that includes adjustable dampers (shock absorbers). Coilovers cost more but allow you to adjust ride height and stiffness after installation.
Effects on ride quality and handling
A lowered truck on Eibach springs will feel noticeably firmer than stock. Bumps and road imperfections that barely registered in the factory suspension will now be felt in the cabin. On a smooth highway, the difference may be subtle. On a rough road or over railroad tracks, the ride becomes noticeably harsher.
Handling improves in the sense that the truck leans less in corners — the stiffer springs keep the body more level, which some drivers find more responsive. However, this does not make the truck faster or safer in emergency maneuvers. The improvement is mainly a matter of preference and feel. If you frequently drive on unpaved roads or carry heavy loads, a lowering kit may make your truck less comfortable and potentially less stable.
Warranty and legal considerations
Installing an Eibach kit may void or limit your truck's factory suspension warranty. Some dealerships will still service other parts of your truck, but suspension-related repairs may be denied. Check your warranty paperwork or contact your dealership before installation if warranty coverage matters to you.
Lowering your truck does not violate federal law, but some states and municipalities have regulations about how low a vehicle can sit. A truck that is lowered 1 to 2 inches is unlikely to trigger legal issues, but extreme lowering (more than 3 inches) may be subject to inspection or fines in some areas. Check your local vehicle code if you live in a state with strict vehicle modification rules.
Cost and where to buy
Eibach lowering spring kits for trucks typically cost between $300 and $800 for the springs alone, depending on the model and kit type. Coilover kits cost more, often between $1,000 and $2,500. Installation labor at a shop adds another $200 to $400. Alignment after installation costs $100 to $200.
Eibach kits are sold through online retailers like Amazon, eBay, and suspension specialty shops. They are also available through some truck accessory shops and performance shops. Verify that the kit is designed for your specific truck model before purchasing, and check the seller's return policy in case the kit does not fit as expected.
Frequently Asked Questions
Will lowering my truck with Eibach springs hurt its towing capacity?
Towing capacity is determined by your engine, transmission, and frame — not by suspension springs. However, lowering reduces ground clearance, which can cause scraping when towing a trailer up a steep driveway. The springs themselves do not reduce your truck's ability to tow, but the lower ride height may make towing less practical in some situations.
Can I install Eibach springs myself if I have basic tools?
Spring installation requires removing the wheels, unbolting suspension components, and compressing the springs — a process that is dangerous without proper equipment like a spring compressor. Most people should have this done at a shop. If you have experience with suspension work and the right tools, it is possible to do yourself, but mistakes can damage your truck or cause safety issues.
Do Eibach kits work with my truck's factory shocks?
Yes, Eibach lowering springs are designed to work with factory shocks on most trucks. However, factory shocks are tuned for factory springs and may feel less responsive with stiffer Eibach springs. Many people upgrade to performance shocks or coilovers at the same time for better overall performance, though this adds to the cost.
How much lower will my truck sit with an Eibach kit?
Most Eibach Pro-Kit springs lower a truck by 1 to 1.5 inches front and rear. Sport-Line kits may lower it by 1.5 to 2 inches. The exact drop depends on your truck's model, weight, and how much cargo you typically carry. Heavier trucks may settle slightly less than lighter ones.
Will lowering my truck affect its resale value?
A lowered truck appeals to some buyers and turns off others. If you plan to sell, you may want to keep the factory springs and reinstall them before listing. Buyers who want a lowered truck will prefer to lower it themselves, and buyers who want stock suspension may see lowering as damage. Resale value depends more on the truck's condition, mileage, and market demand than on suspension modifications.
