All of our manufactored products ship the same day or the next day. Once shipped, you will receive a tracking number along with the carrier name. Some of our parts (Radiators) are built-to-order and may take 2-4 weeks to assemble. Some of our items may be on backorder or in transit from the supplier. Some of our items are shipped from other locations in the USA resulting in longer lead times. If you do not receive a tracking number(s) for your order within 5 days, feel free to send us an email requesting an update.
