Frequently asked questions

To purchase a test box, first it is recommended that you contact us to check availability of the test box you are interested in. If we have yours in stock or you request us build one for you, the next step is to send us a purchase order via email to: [email protected] This will get the ball rolling. Once we have the test box packaged ready for shipment we will contact you for payment. Payment must be received prior to shipment.

Yes we accept for Visa, MasterCard, Discover and American Express for domestic (US) destinations and from US based banking institutions only. While rare, we do accept wire transfers for domestic payments and shipments as well. If you are outside the United States, we require a wire transfer payment. We can provide you wiring instructions.

We do not currently accept PayPal. We try to keep the cost of our test boxes down to benefit the small maintenance shops. This does not allow us enough mark up to absorb the PayPal and credit card fees. We may revisit the policy in the future if the demand requires.

Unlike other companies, we do not profit from shipping charges. We charge what we are charged! The shipping rate will be based on the packaged shipping weight, the package dimensions, and the distance to its destination + insurance for the value of the test box purchased. Most of our test boxes usually weigh around 8 pounds boxed in a 12 in x 12 in x 10 in box. The landing gear breakout box varies by the harness chosen and ships in a larger box.

We ship UPS and FedEx domestically, and we ship UPS, FedEx and DHL internationally. We can bill the charges to your own shipping account if you wish. We have daily UPS service and shipments usually ship the same day as long as the payment transaction is completed prior to 1:00pm Central Time Zone. FedEx only picks up expedited shipments the same day. FedEx Ground shipments usually leave the next business day.

ShockBox has a one year warranty against manufacturing defects. We will repair or replace a defective test box at our discretion. Usually we will choose the option that is faster.

While rare, we do offer a quantity discount to customers who purchase multiple test boxes. If you were to purchase multiple test boxes of the same model, the discount is better than if you order multiple test boxes of different models. We do not offer discounts on a single test box.

No! We are the test box manufacturer, we do not deal in used test boxes. Occasionally, we will have a unit that may have a cosmetic “flaw” in its appearance, but works just fine. We do offer these with a discount if you don’t mind the flaw. You can always ask about availability, but they usually go pretty quickly.

No! While a few of the components used in our test boxes are manufactured abroad, we choose the best quality components available. All our test boxes are designed, manufactured and tested in our suburban Oklahoma City location. Our parent company is a FAA Certified Repair Station and we test all our test boxes in this facility before they go into production.
