🛠 Parts Not Installed by AftertreatmentParts.com

We understand many customers install parts independently. If the part is not installed by our team:

  • The warranty still applies to manufacturer defects

  • However, the burden of proof lies with the purchaser.  Many parts fail due to external factors.

  • The part must be returned for inspection and bench testing

  • If found defective, we will issue a replacement, credit, or refund, at our discretion
