- Coverage is for the original purchaser and isn't transferable. The product must be bought from a Bilstein distributor or retailer in North America, and proof of purchase is required.
What's covered
- Products free from defects in design, material and workmanship for the term above
- Applies to the original purchaser with proof of purchase
What's not covered
- Improper installation
- Racing, competition or off-road use, as Bilstein's off-road warranty page words it
- Modified use, or use on vehicles Bilstein doesn't recommend

How to make a Bilstein warranty claim
- Start with the place you bought the shocks (that's us, if you bought from NVMOS)
- If the original seller can't help, email Bilstein's warranty team to confirm the part is warrantable and get a Warranty Evaluation Form. Don't send shocks in without contacting them first
- Ship the shocks, proof of purchase and the completed form using the label on the form, with tracking and signature. Don't ship with loaded springs, and if a shock is leaking, bag it rather than cleaning it
- Bilstein's quality and warranty teams evaluate the part and contact you with the result
