Bilstein B6 - B8

What is the difference between Bilstein B6 and B8?

They share gas-pressure monotube technology. The B6 is designed to work with the standard springs and ride height; the B8 has a shorter body and stroke to match the working height of a lowering spring. Which one to choose depends on the springs fitted to your car.

Can I fit B6 with lowering springs?

For lowering springs or factory sports suspension, Bilstein recommends the B8, because its working height matches that of the shorter spring. If you are not sure which springs your car has, ask us before ordering.

Do B8 shock absorbers lower the car?

No. Ride height is set by the springs. The B8 does not lower the car on its own: it is the right shock absorber to pair with springs that do. If you want to lower your car, you need to fit B8 together with sports springs.

What is the Bilstein B6 4600?

It is the B6 version for pick-ups, 4x4s, SUVs and vans at standard ride height. It is a 46 mm monotube with a digressive piston, tuned for each vehicle, that also improves control when loaded or towing. It fits the original mounting points.

What is the difference between Bilstein B4 and B6?

The B4 is an original-quality replacement part: it reproduces the valving and ride height of the shock absorber the car had from the factory. The B6 is a sporty upgrade with monotube technology, for drivers who want more control and precision while keeping the standard springs.

What is the advantage of a monotube shock absorber?

Because a floating piston separates the oil from the pressurised gas, the oil does not aerate as it heats up. Damping stays consistent for longer and in demanding conditions, something a conventional twin-tube cannot guarantee in the same way.

How do I know which part number fits my car?

Use the Bilstein B6-B8 finder on this page by entering make, model, engine, date and body type. Each product page states whether it is front or rear. If your car has suspension variants, send us the exact model and we will confirm it.

Do I need to replace them all at once?

At a minimum, replace them in pairs on the same axle so both sides work equally. To feel the full change in how the car handles, ideally fit all four.

Can I finance my purchase?

Yes. You can pay in instalments with SeQura instantly and without paperwork, directly at checkout.
