Radium Engineering-branded products include a one-year limited manufacturer’s warranty from the original purchase date. Coverage applies to the original purchaser and protects against defects in Radium materials or workmanship. After inspection, Radium may repair or replace an approved product at its discretion. Warranty coverage cannot exceed the product’s original purchase price.

The warranty does not cover:

• Improper installation or incorrect use
  
• Product modification, abuse or unauthorized repair
  
• Labor, towing or other secondary expenses
  
• Damage to the vehicle or surrounding components
  
• Third-party products supplied with a Radium kit

Fuel pumps, turbochargers and other non-Radium components are covered only by their original manufacturer, even when purchased with a Radium product. Radium specifically states that it does not administer warranty coverage for fuel pumps.

To begin a claim, contact Elite GT-R Parts with your order number, Radium part number, a description of the issue and clear photographs or video. Relevant installation and vehicle information may also be requested. Do not modify or return the product before receiving instructions. An approved RMA, proof of purchase and the failed component are required, and Radium must receive the return within 14 days after issuing the RMA. The customer is responsible for prepaid shipping to Radium for inspection. Final warranty eligibility and resolution are determined by Radium Engineering.
