Description
Improved Performance. Give your S197 Mustang a suspension upgrade and make your next drive exhilarating. Tighter steering, sportier handling and a more aggressive appearance are all yours with the KONI STR.T & Eibach Pro-Kit. The set includes KONI STR.T Street Front Struts and Rear Shocks as well as progressive rate Eibach Lowering Springs.
Full Handling Kit. KONI's STR.T & Eibach Pro-Kit is the perfect starting point for the budget-conscious driving enthusiast. The entry-level STR.T Series Shocks and Struts from KONI offer the superb engineering and workmanship that KONI is known for, but in a design that makes for a wallet-friendly price point. The Pro-Kit Lowering Springs by Eibach provide a nice drop that improves overall stance without the harsh ride some other springs provide. Bundled together, the combo is a great value for daily drivers and performance minded folks alike. The STR.T Shocks will require bushings which are sold separately.
Quality Construction. Complete with a gas pressurized twin-tube design, the KONI STR.T Shocks and Struts feature a durable orange finish and a larger diameter piston for optimum street performance. These non-adjustable dampers are great stock upgrades and also perfectly complement the included Pro-Kit Lowering Springs. The progressive rate springs provide a comfortable ride while lowering your center of gravity, offering better handling in curves and a reduction in nose-drive under hard braking situations.
Installation Tips. This Handling Package installs directly in place of your stock components and comes with everything you'll need, including illustrated instructions. A full 4-wheel alignment should be completed after installation. The initial drop may appear be less than expected, but springs will settle farther given a bit of time. Expected drops vary by model and body style:
