How to choose the correct Bilstein shock absorber.

It can be confusing, do I need B4 or B6? What about B8? What’s the difference? What’s best?

To answer this question you need to know what you’re trying to achieve by changing the suspension, here are some pointers to help you choose the right Bilstein suspension for your car and more importantly for you, the driver.

So to help you decide you need to know the differences between the ranges.

Bilstein B2 and B4 are replacement dampers, another words if you need to replace your shocks because your cars failed its MOT then choose B2 or B4.

Bilstein B6 and B8 are uprated shock absorbers. If you are looking to improve the vehicle handling you should consider B6 or B8. If you want to retain the vehicle ride height or you do a lot of towing and want a firmer rear suspension the B6 is for you.

If you have a lowering springs fitted to your car you need B8. The B8 damper is a shortened damper and only suitable for use with lower springs.

Other things to consider before you buy!

The price difference between B4 and B6 is significant, this is because the uprated dampers are very different in construction. Generally the B4 is a twin tube design while the B6 and B8 are mono-tube.

If you want to retain your ride comfort, choose B4. Fitting B6 will make your ride firmer, not uncomfortably firm but you will notice a significant difference.

If you are changing your shock absorbers always change a pair across the same axle, another words do not just change just one rear shock, change them both! This is important, shocks do wear out. You really wouldn’t want a worn shock on one side and a new on the other, your vehicle handling will seriously effected especially in an emergency situation.

I hope this helps you choose but we are here to help you if needed!
