Choose quality components in your car

Excel-G shock absorbers from KYB are used by vehicle manufacturers and aftermarket repair shops across the world. The shock absorbers and struts are designed for maximum handling and comfort. Our patented valving and the use of pressurised nitrogen gas in the Excel-G range significantly reduces the aeration and foaming that typically occurs in other shock absorbers. That means greater performance over a greater shock life.
