Lifetime Warranty

Our products are made to take a beating and actually be used, but we understand there are wearable components that may fail over time. Whether it's the gas shocks, rubber seals, or latches, give us a call and we'll do whatever we can to get you taken care of. For the box itself, we offer a lifetime warranty in overall construction and build quality. Things like scratches in the powder coat, small dings, or any other regular wear and tear is to be expected and will not be covered in our warranty. But for everything else, we'll take care of you.
