Replacement Coil Springs

Is your car sitting lower on one side, or has a spring snapped at the bottom coil? This category contains coil springs that replace the original springs and typically bring your car's ride height and suspension back close to the original level. They are for you if you want to repair rather than lower or raise your car.

What a replacement spring does

The coil springs carry the car's weight and, together with the shock absorbers, determine how the car handles on the road. Over the years a spring can sag so the car sits lower, or it can break. Often you first notice it from uneven ride height or a clunk over bumps. A replacement spring is typically made to give a ride height and spring characteristic close to the original. Lowering springs and lift springs, on the other hand, change the height deliberately. You can find all spring types together under suspension springs.

How to choose the right spring

Springs are specific to car, model year and axle, so always check the part number against your car. Pay particular attention to these factors:

• Car and model year: For example, there are Bilstein B3 springs for the BMW 3 Series, BMW X3, Mercedes-Benz E320 and Audi A4 Quattro. Fitment depends on the specific variant.
• Front or rear axle: The springs are divided by position, because front and rear springs are different.
• Equipment and weight: Engine, all-wheel drive and optional equipment can affect which spring your car needs.

Replace springs in pairs on the same axle so the car sits level and the suspension behaves the same on both sides. If the shock absorbers are worn, it can pay off to replace them at the same time. Brands in this category include Bilstein and OMIX.

Frequently asked questions

Do I need to replace springs in pairs?

Yes, we recommend replacing both springs on the same axle. A new and an old spring typically have different height and stiffness. This can result in a car that leans and suspension that differs from side to side.

Can I fit new coil springs myself?

It depends on the car and axle. The spring is under high tension, so fitting typically requires a suitable spring compressor and experience. Have the wheel alignment checked after the replacement, as the ride height may change.

How can I tell if a spring is broken or has sagged?

Typical signs are that the car sits lower on one side, that there is a clunk over bumps, or that a piece of the bottom coil is missing. Measure the ride height on both sides and compare the two measurements.
