AftertreatmentParts.com warrants that all new parts sold are free from defects in materials and workmanship under normal use and service conditions.

Product Type Warranty Period

All Other Components 365 days from purchase date

Warranty coverage begins on the date of purchase, not installation.

❌ What’s Not Covered

  • Improper installation, contamination, or incorrect application

  • Damage from abuse, impact, modification, or other system failures

  • Normal wear and tear

  • Shipping, customs, duty fees, brokerage

  • Labor, diagnostic time, downtime, shipping, towing, or other incidental or consequential costs

🛠 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

🔄 Warranty Claim Procedure

  1. Submit your claim using the form at the bottom of this page

  2. Return the part to our warehouse (we'll provide return a shipping label)

  3. We inspect and test the part to confirm the issue

  4. Upon validation, we’ll issue a replacement, store credit, or refund

⚠️ Important Note on Replacement Purchases

If a customer purchases a replacement part from another source before returning and receiving a warranty decision from AftertreatmentParts.com:

  • The warranty claim may be denied

  • We require a fair opportunity to evaluate the part

  • If your part fails under warranty, we will provide a replacement, not a refund.
