Eibach Lowering Springs are some of the most popular springs on the market – and for good reason. Eibach is the leader on street and race technology with everything from direct replacement lowering springs to high performance coilover springs in various sizes and spring rates.
Of their lowering springs line, Eibach offers two main choices, the Eibach Pro Kit Lowering Springs and the Eibach Sportline Lowering Springs. Many people do not know the differences between the two, so we decided to create this point to easily reference the difference of the Pro Kit vs Sportline.
Eibach Pro Kit Lowering Springs
The most popular amongst Eibach’s offering is the Pro Kit lowering springs. These lower your vehicle enough to clean up a lot of the wheel gap, but are not very aggressive in their spring rates or drop rate. This allows for you to keep your ride quality and be able to use the OEM shocks, usually with no problem for many years (unless if your OEM shocks are old and worn).
Eibach Sportline Lowering Springs
These lower your vehicle more than the Pro Kit and also have stiffer and spring rates. Usually, with Sportline, we recommend to replace your shocks to be able to handled the extra amount of lowering and stiffer springs, but generally many customers use Sportlines with stock shocks with no problems.
Eibach Pro Kit vs Sportline
So while the Sportline lowers more than Pro Kit, they do share some features in common. For example, they both lower your center of gravity, have progressive spring rates, excellent ride quality and a million-mile warranty.
