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.

Frequently Asked Questions

Can I replace my Audi A4 shocks myself?

Replacing shocks requires you to lift the vehicle to the right height, as well as more specialised equipment such as the coil spring compressor. Do not attempt to replace the shocks on your vehicle if you cannot safely raise it to the required working height.

How long do Audi A4 shocks last?

We recommend replacing shocks and struts every 80 000 km. If you’re experiencing lack of control or nose-dive when operating your vehicle, your shocks could be worn and should be inspected by a mechanic immediately.
