If a RalliTEK branded product covered by this warranty fails due to a manufacturing defect we will repair the product, without charge, or replace it at our discretion. This policy covers only original, unaltered, and unmodified materials and workmanship. This warranty does not cover damage caused by incorrect installation, accident, improper care, negligence, normal wear and tear, or the natural breakdown of colors and materials over extended time and use. Damage not covered under warranty may be repaired for a reasonable rate and a fee will be charged for return shipping.

For warranty evaluation, please contact RalliTEK Customer Service at (503) 619.0055 or to obtain a return authorization.

  • This warranty gives you specific legal rights; you may have other rights, which vary from state to state.
  • This warranty does not cover products sold by RalliTEK that are not RalliTEK branded products.

The RalliTEK website sells discontinued, special markup, and slightly blemished products at significant discounts as 'factory seconds' products. This warranty does not automatically cover products purchased as factory seconds. RalliTEK reserves the right to determine if any warranty applies on a case-by-case basis for factory second parts. If approved, the RalliTEK Warranty Department may repair factory second products for a reasonable charge and applicable shipping charges.


Non-RalliTEK branded products do not have any written or implied warranties. Products on are sold with the warranty applied directly from the manufacturer. The customer must contact the product brand manufacturer for any warranty details. All products sold by RalliTEK are intended for off-road and/or race use only, as suggested by the manufacturer, and should be installed and set up by professional service centers only. RalliTEK is not responsible for any product failure or failure due to installation. Should a warranty claim arise, the customer and the manufacturer will handle all warranty issues directly.

Some states do not allow the exclusion or limitation of incidental or consequential damages so the above limitation or exclusion may not apply to you. This warranty is governed by the laws of the State of Oregon.
