Warranty Guard

This free protection supplements your manufacturer's warranty, guaranteeing that if you are denied repair due to having a Warranty Guard protected product on your vehicle, then Rough Country will foot the bill for your repair! For up to 5 years / 100K miles / or until your manufacturer's warranty ends, if there is a failure of a factory warranty-covered part due to installation of a Rough Country suspension product, Rough Country will cover the repairs at a factory authorized shop - all you pay is a $100 deductible!

These items are covered under a separate Limited Warranty along with other non-suspension items listed above. Replacements for non-defective items broken during off-road use may incur shipping charges.
