Does Bilstein Make Complete Strut Assemblies?

If you've been shopping for Bilstein struts, you've probably noticed something: it's almost impossible to find a Bilstein "complete strut assembly" — the kind that comes pre-loaded with a coil spring, strut mount, bearing, dust boot, and bump stop, all ready to bolt in. There's a good reason for that.

Bilstein Doesn't Manufacture Complete Strut Assemblies

Bilstein produces bare struts and bare shock absorbers — not pre-assembled strut kits. Out of the thousands of applications Bilstein covers, they make only one complete strut assembly, and it's for a specific Mercedes-Benz application. That's it.

Unlike brands such as KYB (Strut-Plus), Monroe (Quick-Strut), and Gabriel (ReadyMount), Bilstein has never mass-produced loaded strut assemblies. They don't manufacture coil springs, strut mounts, or upper bearing plates. Their focus is — and has always been — on engineering the best possible shock absorber and strut cartridge.

What About Third-Party "Bilstein" Complete Strut Assemblies?

You may see complete strut assemblies sold online that include a Bilstein strut with a spring and mount already installed. These are not assembled by Bilstein. Third-party companies purchase Bilstein struts and pair them with aftermarket springs and mounts from other manufacturers.

There are some important things to know about these third-party assemblies:

• The spring and mount combinations are not tested or approved by Bilstein. Bilstein's engineering team has not validated these pairings for ride quality, spring rate compatibility, or long-term durability.
• Warranty coverage may be limited or void. Since Bilstein did not assemble the unit, their standard warranty may not cover issues related to the spring, mount, or the interaction between components.
• Quality varies widely. Some aftermarket assemblers use low-cost springs and mounts that may not match OEM specifications. Customers have reported noise, premature wear, and ride quality issues with some of these products.

If someone offers you a "Bilstein complete strut assembly," ask who assembled it and what warranty covers the full unit — not just the strut cartridge inside.

So What Should You Do If You Want Bilstein Struts?

You have two solid options:

Option 1: Buy Bilstein Bare Struts + Reuse Your Existing Hardware

If your coil springs and strut mounts are still in good condition, you can purchase Bilstein bare struts and transfer your existing springs, mounts, and hardware onto the new struts. This requires a spring compressor (or a shop with one) and is the most common approach for Bilstein strut installations. This is also the standard method that professional shops use.

Option 2: Buy Bilstein Bare Struts + New OEM-Quality Springs and Mounts Separately

If your springs are sagging or your mounts are worn, buy the Bilstein struts along with separate replacement springs and strut mounts from a quality manufacturer. This gives you a complete refresh with components you can verify are the right specification for your vehicle.

Why Bilstein Struts Are Worth the Extra Installation Step

Bilstein's monotube gas-pressure design delivers consistent damping performance, superior heat dissipation, and a longer service life than most competitors. Their struts are built to OEM or better-than-OEM standards for specific vehicle applications. The fact that they don't cut corners by bundling unmatched springs and mounts is actually a testament to their engineering standards.

For drivers who want the best damping performance available, Bilstein struts paired with quality springs and mounts — whether OEM or carefully selected aftermarket — will deliver a ride that pre-assembled budget kits simply cannot match.
