This warranty covers factory defects in material and workmanship other than finish and coatings.

FOX is not liable for removal, installation, or reinstallation costs, including labor. If FOX determines a product is covered, it will be repaired or replaced with a comparable model at FOX's sole discretion — this is the exclusive remedy, and incidental, consequential, or punitive damages are excluded. Normal wear and tear, and failures from abuse, improper assembly, neglect, alteration, improper maintenance, crash, misuse, or collision are not covered.
