Steelcraft guarantees the original purchaser a LIMITED LIFETIME WARRANTY against manufacturer defects in materials, workmanship, and finish under normal use excluding damage resulting from road hazards, debris, product misuse, improper installation, impairments from accidents, neglect, shipping or product modification. This warranty applies only to new products and is limited to the repair or replacement of Steelcraft products. Warranty does not include the cost of removal, installation, labor, freight, inconvenience, or consequential damage. The original purchaser must return defective merchandise to the original place of purchase and must provide the original receipt.

Steelcraft products are designed as decorative accessories and should not be relied upon as protection for the vehicle or passengers. Buyers assume all risk and liability whatsoever resulting from the installation and use of Steelcraft products. Steelcraft assumes no liability for injury, loss, incidental or consequential damages in the event of an accident.

Steelcraft products should be routinely cleaned with a mild soap and water solution then dried fully with a clean dry terry cloth.

Failure to do so may cause fading, corrosion, and ultimately void product warranty.
