There are several great offerings from Eibach for replacement shocks that are valved specifically for lowering springs so the performance benefits of your springs will be increased along with the peace of mind that comes with their 2-year warranty. Most shock absorbers last between 40k-80k miles depending on vehicle weight, driving habits, and road conditions. If you are in that area we definitely suggest looking at upgrading or replacing your shocks while you are installing lowering springs.
