Gas-pressure makes the difference!
Bilstein B4 shock absorbers are designed to offer like for like performance with OE shock absorbers. Replacing your worn shock absorbers with Bilstein B4's will restore handling and ride comfort to your car.
Shock absorbers are a wear item, and can be showing noticable signs of wear long before they would fail an MOT. Worn shock absorbers can effect cornering, braking, acceleration, and tyre life.
BILSTEIN B4 Features and Benefits
- High power reserves for maximum safety
- Optimum driving experience as on day one
- High OE quality
- Constant damping power under any load
- High traction and precise handling thanks to BILSTEIN gas-pressure technology
- Comprehensive product range with high market coverage and availability
OE. Replacement.
Bilstein B4's are designed to match your cars original suspension, so they will work happily with either standard ride height springs or mild lowering springs. Up to around 30mm is normally fine, but this depends on application.

Stock at Progressive Parts
Delivery timescales are given as estimates in good faith, but cannot be taken as precise or exact information. We highly advise against booking installation/workshop time or engaging in preparatory work until you've received and inspected the goods.
What do our stock statuses mean?
1+ IN STOCK in green stock is readily available in one of our warehouses for express delivery (at the time of viewing).
LOW STOCK in green means we're running low! 1 or 2 left on the shelf so act fast. Over evenings, weekends and bank holidays this stock can move quickly so please bear this in mind.
0 IN STOCK in blue means our primary warehouse does not have unallocated stock, but our UK partners do. Often these can be shipped quickly and efficiently. You'll be notified via the Track My Order page if further delays are unavoidable.
MADE TO ORDER in blue means we've partnered with a supplier which primarily makes their products to order. It's not on our shelf, but your order goes into production immediately.
0 IN STOCK in orange means everybody we work with is unfortunately out of stock. Stock is not available in the UK. The best course of action is to place an order to create an allocation from the next batch arriving.
OUT OF STOCK in red. This product is unavailable to order, for whatever reason we're unable to obtain stock or there is an issue with supply/lead times.
We're tuners too!
Our staff are car enthusiasts, we understand the need for speed... This includes getting your orders out the door as quickly and securely as possible!
In some instances, extended lead times are unavoidable. This is as labour-intensive and frustrating for us as it is for you, please know we are doing our best to facilitate your modification goals. Abuse of our staff or systems will not be tolerated.
Thank you, Team PP
In the words of the Vehicle Standards Agency (VCA), type approval provides "confirmation that production and samples of a design will meet specified performance standards".
For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
