Shipping policy

Thank you for choosing Mammoth Performance. We pride ourselves on getting your high-performance parts out the door and onto your vehicle as fast as possible. Below are the specific details of our shipping operations.

1. Rapid Order Processing

We know you need your parts to get back on the road. That’s why most orders are shipped the same day they are placed.

Standard Processing: Orders placed before our daily cutoff 12:00 PM ET are processed and dispatched the same business day.
Business Days: Our shipping department operates Monday through Friday. Orders placed on weekends or federal holidays will ship the following business day.

2. Shipping Methods & Estimates

We primarily partner with UPS to ensure reliable and trackable delivery. Shipping charges are calculated and displayed at checkout based on weight and destination.

Shipping Method	Estimated Delivery
UPS Ground	1–5 Business Days (Standard)
UPS Second Day Air	2 Business Days
UPS Next Day Air	1 Business Day

3. Expedited Shipping Requirements

If you are in a rush and select Next Day Air or Second Day Air, please note the following strict requirement:

12:00 PM EST Cutoff: Expedited orders must be received in our system by 12:00 PM Eastern Time Monday to Friday to guarantee same-day dispatch.
Orders received after this time will be prioritized but may not ship until the following business day.

4. Shipping Destinations

Continental U.S.: We ship to all 48 lower states via UPS.
Alaska & Hawaii: Shipping is available but may incur higher rates and longer transit times.
P.O. Boxes: Since we ship via UPS, we require a physical street address for delivery. We cannot ship to P.O. Boxes.

5. Shipment Tracking

Once your label is printed and your parts are packed, you will receive a Shipment Confirmation email containing your UPS tracking number. Please allow a few hours for the carrier to scan the package and for the tracking status to update.
