6-Month FREE Warranty Included:

We offer an industry leading 6 months / 6000 miles warranty on every part type we sell. All of our engines and transmissions carry a 6 months / 6000 miles warranty. Claims on engine warranties are limited to manufacturer defects in the pistons, heads, block, crankshafts, rockers, and oil pumps. Though additional parts and accessories may be attached upon purchase, coverage does not extend to sensors, switches, cables, electronics, belts, hoses, water pumps, or manifolds, nor damage caused through overheating or improper lubrication. All warranties are null and void if:

• The vehicle is converted from a private passenger use to commercial or fleet use, or is used for racing or other competition or off-road recreational purposes, or used for ride share or delivery.
• Failure is caused by abuse, misuse, or modifications.
• Failure is caused due to not following the OE's maintenance schedule.
• Failure is caused by using the part for any use other than what was intended or recommended by the manufacturer.
• The part fails or becomes defective due to the vehicle being involved in a collision.
• The part is installed or operated outside the United States.
• The installed heat tab center is melted or removed.
• The part is sold "as is" as indicated on the packing list or in a statement of terms on the website.

Fast Shipping Nationwide:

We offer FAST shipping on all orders to the U.S. continental 48 U.S. states. We can ship anywhere in the contiguous U.S. including residential and commercial addresses. We do not require a core charge or the return of the engine core. If you need a lift gate, we also offer it for free upon request at checkout. Our standard delivery time is 3-5 business days after processing your order, which takes 2 to 3 days for LTL items. Want it faster? Shop for items nearest you.

Canadian Orders:
Currently we do not ship to Canada. We can ship anywhere in the 48 continental US states.

Alaska/Hawaii/Puerto Rico orders:
Orders outside of the continental 48 states (Alaska, Hawaii, and Puerto Rico) may be subject to additional shipping charges for extra freight costs.

Can I change my shipping address after I placed my order?
We are limited on our ability to change a shipping address on an order. The only address change we can allow, is a change from residential to a commercial address (within the same geological area—35 miles or less). Once we receive your request, we will review the requested change, and either approve or disapprove. We have this policy in place to combat fraud on orders. If the shipping address change is after your order ships, a change of shipping address fee may apply and must be paid via credit card. We will send you a link for processing your payment.

Shipping LTL items to my house
We can ship LTL items (Engines, Transmissions, Rear Axles, Transfer Cases, and more) to both residential and commercial addresses. For most commercial deliveries, the carrier will simply show up during normal business hours to make delivery; however, they may call to schedule a delivery. For residential addresses, the carrier will call a day or 2 in advance to schedule a delivery. It is very important to schedule the delivery, as the carrier will not make a delivery without it. You will also need to make sure someone 18 or older is there to receive the order. Failure to schedule delivery with the carrier will result in your order being returned back to us. You will be issued a refund less the original freight charges and the cost to redirect back to our facility. Redirect fees usually start at $150.

Why is shipping so high on airbags?
Airbags are considered hazardous material by the US Department of Transportaion and require special and additional handling for safe shipment.

Refusing Delivery of an Order
If you refuse delivery from the carrier, the part will be returned back to one of our facilities. Once received, it will be processed and a partial refund issued. Your refund will be less the original freight and the return costs.

Why can’t I ship airbags to my New York Address
New York state law bans the installation of used airbags in vehicles; therefore, we cannot ship into the state of New York.
In addition to New York, we can't ship airbags to any address outside of the continental US.

Parts being returned back via LTL (engines, transmissions, rear axles, etc.)

• We would recommend insuring the part in case it gets damaged during transit back to us, as you'll be responsible for paying for the replacement.
• Place the part on a pallet. If the pallet isn't included with the part, you can usually obtain one from a nearby big box store (hardware store, grocery store, flooring store, etc.)
• Attach the part to the pallet. When it was shipped, the part was securely fastened to the pallet using rope or straps. If you use ropes, ensure that the rope is tied tightly and won't shift or move on the pallet. If the part isn't properly secured or isn't on a pallet, the carrier may refuse to pick it up.
• We'll provide you with a shipping address and an RA #. Please ensure that the RA # is attached to the part so that our warehousing team can identify the correct order.
