Shipping Policy

Same Day Shipping

Same day shipping is available for most orders placed before 12:00 PM Central Time, Monday through Friday. Same Day Shipping does not apply to orders shipping via LTL Freight or Special Orders. Same Day Shipping is not available on most US Holidays.

Shipping Methods

We ship most orders via FedEx and UPS. In some instances, items may ship via USPS, Speedee Delivery, DHL or other carriers.

Shipping Charges

Due to recent price increases for shipping, we will not offer any free shipping.

LTL Freight

We reserve the right to ship your order via an LTL Freight carrier service. We will contact you beforehand to verify your business address and forklift/dock access before shipping via an LTL carrier. We will absolutely not ship any orders via LTL to any home addresses without an additional freight charge of $300. If you represent your address as a business address but it is a residential address, you will be assessed a $300 freight delivery fee.

Shipping Costs

Shipping costs are non-refundable. In rare instances, the billed freight charge may be insufficient to cover the actual freight cost. These usually boil down to technical problems with the FedEx or UPS API we use to obtain shipping quotes, mis-entered addresses, weight and/or box dimension calculation errors, etc. We may contact you for an additional payment to cover the extra freight cost to ship your products. If the freight charge looks too good to be true, please call us before ordering to check. If you choose not to pay the extra charge, your order will be cancelled with no conditions or fees.

Damaged Parts

If your order arrives in a box that is damaged, it is your responsibility to report the damage to the carrier and contact us immediately. Please take pictures before moving the parcel if possible. If a part was damaged during transit, please notify us immediately for return and replacement.

Missing Packages

We, MJ Heavy Duty Parts LLC, are not responsible for packages that are missing after delivery. We will work with the carrier to help you locate your package. Most carriers “geo tag” a package’s coordinates when it’s scanned and take photos of where the package was delivered and can pin-point exactly where the driver was when they delivered the package.

Mis-Delivered / Wrong Address

If a package is delivered to the wrong address due to the fault of us or the carrier, we will take care of shipping costs to make sure that package gets to you as soon as possible. If a package was delivered to the wrong address because of a mistake on your end, it is your responsibility to pay the extra shipping charge to get the package to you.

Order Policy

Special Orders

Special order parts cannot be cancelled once the order is processed. Special Orders are non-returnable and non-refundable. Special Orders may take 6-10 weeks, or longer, for delivery. You will be provided an estimated lead time for shipment before the order is processed but we cannot guarantee that date. Please be aware that we are at the mercy of the manufacturer for special orders and an order status can change at any moment.

Cancelling Orders

Orders are processed almost immediately during the work week. You may cancel an order if it has not been shipped yet. If your order has been shipped, ie it has a tracking number and has been marked as shipped, you may cancel your order for a 15% cancellation fee. 

Returns, Refunds and Exchanges


We have a 14-day after delivery return period. If you wish to return any parts during this time, please initiate an RMA from the My Account Page or call us at 800-435-3509 during business hours. Please note, you are responsible for the return shipping cost. All returns are subject to a 15% restock fee. Your original shipping cost will not be refunded. If 14 days have elapsed since your package was delivered, we will not accept your return. Items must be in original, unused, uninstalled condition and will be inspected upon return for any damage, signs of installation and use. If the item is deemed to be in un-saleable condition, your refund will be denied and if you choose to keep the part, you will be responsible for return shipping. Refunds are given for the part only and does not include the original shipping costs, return shipping costs, any labor, time, compensation for aggravation, etc.

Please do not return your parts to the manufacturer or shipping warehouse unless directed to do so. Follow the RMA directions carefully. Any parts returned to the manufacturer or shipping warehouse without consent will forfeit any refund and the parts will be returned to you postage due.

-          Original order number written on the box or label

-          Legible copy of the invoice

-          Legible copy of the RMA

Your return processing may be delayed, and you will be assessed an additional restocking fee of the greater of $25 or 15% of original order total.

Once your return is received and inspected, we will send you an email to notify you that we have received your returned item. We will also notify you of the approval or rejection of your refund. If you are shipping an item over $50, you should consider using a traceable shipping service or purchasing shipping insurance. We cannot guarantee that we will receive your returned item.


If your return is approved, then your refund will be processed, and a credit will be applied to your credit card or original method of payment within 5 days of us receiving the return.

If a part is returned to us, or the shipping warehouse, without authorization or RMA, it will be returned to you at your expense.


All exchanges will incur a 15% restocking fee. This fee will be deducted from your exchange credit. Original shipping charges are non-refundable. You are responsible for the cost of return shipping of the original parts.

We only replace items if they are defective or damaged. If your part arrives in a box that is damaged, it is your responsibility to report the damage to the carrier immediately. We will help in any way we can, but we are not responsible for damage caused by carriers.

If you need to exchange it for the same item, give us a call at 800-435-3509 between the hours or 9am and 2:30pm CDT Monday – Friday to request an RMA.
