KYB's Excel-G shock and strut is the ultimate compromise of smoothness and control, providing enthusiasts with great performance as well as comfort. Intended to work great with both OEM springs and aftermarket lowering springs, the Excel-G features a twin tube design for great ride quality and response. It uses a low pressure gas charge and check valve to minimize foaming and aeration to ensure good ride quality. The Excel-G is ideal as an OEM replacement or a performance upgrade and is designed to withstand virtually all types of road condition. KYB valves each Excel-G shock to work with your specific application and is designed to exceed OEM build standards. All Excel-G shocks are also calibrated to compensate for other worn suspension components on your vehicle that might wear out your stock struts over time. If you are looking for reliability, durability, and performance, look no further than the KYB Excel-G!
