Bilstein B6 Front Damper Insert for BMW E24 and E28 5/6 Series | Part No. 34-002421

Transform the way your classic BMW turns in, rides and grips with the Bilstein B6 front damper insert. This uprated, gas-charged monotube cartridge drops straight into the original front strut body on E24 6 Series and E28 5 Series applications including 533i, E28 M5 and M635 CSi, delivering crisp steering feel, superb body control and confidence on fast road without sacrificing everyday comfort.

We run these on customer builds and our own cars. Feedback is the same every time: tighter chassis behaviour, flatter cornering, less float, better bump control and a more composed motorway ride compared with tired factory units. If you want an OE-quality, direct-fit upgrade that genuinely sharpens your classic BMW, this is it.
