Product Information

Full details

The SACHS 900 338 Service Kit is an essential maintenance solution for BMW owners seeking to preserve their vehicle's suspension integrity and comfort. Designed for DIYers and professional mechanics alike, this kit protects critical shock absorber components from road debris, moisture, and grime, ultimately extending the lifespan of your suspension system. While it offers premium OEM-grade protection, it requires a full suspension disassembly for installation, making it a task best suited for those comfortable with advanced automotive maintenance.

Extended Product Information

FAQs

Does this kit fit both front and rear shocks?

This kit is application-specific; please verify your vehicle's specific requirements against the SACHS compatibility catalog for your exact BMW chassis.

Do I need to replace these every time I change shocks?

Yes, it is standard industry practice to replace the dust covers and bump stops whenever you replace the shock absorbers to ensure the new parts are fully protected.

Is this kit compatible with electronic suspension (EDC)?

Yes, the kit is engineered to be compatible with BMW electronic suspension control systems.

Will this fix a leaking shock absorber?

No. The kit is designed to prevent leaks by shielding the rod, but it cannot repair a shock that is already leaking.

Can I install this without a spring compressor?

No, it is dangerous to disassemble suspension struts without using a professional-grade spring compressor.

Troubleshooting

Gaiter keeps slipping off the seat

Ensure the mounting surfaces are completely clean of grease and debris before installation to provide a proper grip.

Suspension makes noise after installation

Check that the bump stop is properly seated and that the shock mount hardware was torqued to the manufacturer's specified values.

Pros and Cons

Pros

  • High-quality, durable materials designed for long-term use
  • Restores original factory protection levels for suspension components
  • Prevents expensive future shock absorber repairs
  • Wide compatibility across popular BMW F-series platforms

Cons

  • Requires professional-grade tools for installation
  • Involves removing shock absorbers, necessitating an alignment afterward
  • Not intended for suspension lowering kits without verifying compatibility

Setup, Compatibility & Care

Installation of the 900 338 kit involves the full removal of the shock absorber unit. It is highly recommended to use a proper spring compressor tool during this process.

Compatibility List:

  • BMW 5 Touring (F11)
  • BMW X5 (F15, F85)
  • BMW X6 (F16, F86)

Care Instructions:

During routine tire rotations or brake inspections, visually inspect the gaiters for tears or cracks. If you notice fluid leaking from beneath the boot, the shock absorber itself may already be compromised, and the protective cover should be replaced alongside the shock unit.
