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.

No payment or reimbursement shall be made for installation, removal, transportation, or other charges. The remedies outlined in this instrument are exclusive and the liability of RalliTEK with respect to any sale shall not exceed the price of the product on which the liability is based.

If approved, the RalliTEK Warranty Department may repair factory second products for a reasonable charge and applicable shipping charges.

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.
