What is the benefit of a progressive spring rate?

A progressive spring rate means the spring's stiffness changes depending on how much it's compressed. During normal driving, it offers a comfortable ride. When you corner hard or encounter rougher roads, the spring rate increases, providing more support and reducing body roll.

Will these springs affect my car's ride comfort?

H&R Sport Springs are designed with a progressive spring rate that aims to provide superb ride quality and comfort for everyday driving, even though they lower the vehicle.

Do these springs come with new bump stops or other hardware?

This product includes the lowering springs only. It is recommended to inspect your vehicle's existing bump stops and other suspension components during installation and replace them if necessary.

Product Details

If you're looking to give your 2005-2011 Mercedes-Benz SLK350 a more aggressive stance and better road manners, H&R Sport Springs are a popular choice. These springs are designed to reduce the gap between your tires and the fender wells, giving your car a lower, sportier profile. By lowering the vehicle's center of gravity, they also help reduce body roll during cornering, which can make your SLK feel more planted and responsive on the road.

H&R uses high-strength 54SiCr6 spring steel for these springs, which is shot peened to increase its resilience and durability. The progressive spring rate design is a key feature here; it means the springs offer a comfortable ride during normal driving but stiffen up when you need them to during spirited driving or hard cornering. This design helps maintain a superb ride quality without sacrificing performance. Being made in Germany, these springs are well-built and a solid option for improving your car's suspension.

These springs are H&R's best-selling product, and for good reason. They offer a noticeable improvement in both the look and the handling of your SLK without requiring extensive modifications. While they do lower the vehicle, the progressive rate aims to keep the ride comfortable for daily driving.
