At XLR Industries, we take pride in our work and in our products. We also value your satisfaction. Because of these ideals, we offer a LIFETIME WARRANTY against manufacturing defects and structural performance on all products we offer. We will repair or replace your product if it becomes damaged or defective at no charge to you. If we cannot repair your product, we will replace it with a comparable current product. Our lifetime warranty is fully transferable, so even if you purchased the chassis second hand, we will still stand behind our product.

We do not cover cosmetic damage such as scratches or color fading.

If the chassis has been modified by the user in a manner that causes failure, we may at our discretion, void warranty on that part of the chassis.

If at any time you have questions or concerns about your chassis, please do not hesitate to contact us by email or phone.
