Welcome to SuperiorDiesel.net!

This is the first phase of our e-commerce site. Currently if you have an open account with us you can place your order online and your account will be billed accordingly. All you have to do is sign up for a web account here and start shopping. We will call or email you if there are any problems with your order. Or you can call us at 800.662.7953 and press 4 if you have any questions.


All prices are subject to change without notice. All of our parts information is as accurate as possible, but occasionally the price or the part numbers may be changed by the manufacturer and some become obsolete. We make every attempt to be as accurate as possible, however, as we are human mistakes are sometimes made. Some weights listed are approximations based on price and your actual shipping charges may vary slightly. We will contact you if there is a large difference between the quoted shipping price and our actual charges.  Actual restocking fees in the event of cancellation or return are the responsibility of the customer for all special orders. If you are returning a part to us, you must include the original packaging. We will make every effort to fill your order and will notify you of any part which we are unable to provide to you in the event of low stock, no stock, or discontinued items.
