Thank you for visiting our website here at Redline Tuning. If you are having a specific issue with one of our products, please prepare for the following questions we will first ask you when calling or writing us.

Warranty Questions
  1. Proof of purchase - we will need to see specifics about the purchase. If a direct purchase from redlinetuning.com, we will have this information once given your full name, address or email. If you have purchased from one of our resellers, have a copy of that receipt (including Amazon, etc.) so that we know the date and item purchased.

  2. Proof of failure - if your system is not working as intended, determine the issue as best as you can. For gas springs that go bad, there is a 4 year warranty on all black struts and 5 year on stainless steel struts. Remove them from your vehicle, determine which one is bad by compressing each one to the floor. A failed gas spring will compress easily compared to one that is working correctly.

  3. Contact us - once you have best determined the issue, call or email us with the above information. For issues within the first year of purchase, we will likely send out a replacement part with the information above. However, issues after 1 year will require customer to send us the failed item for evaluation where will repair or replace item. In those cases, please use the following link (warranty replacement).
