Precisely tuned together during road testing, Bilstein’s monotube gas-pressure shocks and Eibach’s sport springs offer not only a sportier and more aggressive look but also improved performance that pushes your vehicle to its limits. The Upside-Down monotube design from Bilstein allows for better greater dampening power and distribution of support and lateral forces for better torsional strength. Meanwhile, Eibach’s lowering springs feature progressive characteristics, offering even lowering between 30 and 60mm depending on the application. All necessary bushings, nuts, and washers are included in this kit for easier and faster installation. And since it’s covered by Bilstein’s Limited Lifetime Warranty, you can buy with confidence today.
