BEFORE DELIVERY

Orders placed by 1 p.m. Central Standard Time are typically processed the same business day. Weekend orders are processed first thing Monday morning. Many of the products we sell are drop shipped directly from warehouses throughout the country.

Expected ship dates are best estimates based on past shipping times. They are more than 90% accurate. Should a significant delay in shipping occur, we will notify you by email of the new projected shipping date and provide you with an opportunity to keep your order or cancel it.

In-stock items usually ship in 1-2 business days (weekends and holidays are not considered business days).

Please allow an additional 1 to 5 business days after the shipment date for transit and delivery. You will receive an email with tracking info, so you can follow the shipment along its path to you.

FREE SHIPPING

Get Free Shipping on qualified items without hidden fees.

Rock Bottom Truck has Free Shipping everyday on many of our products, saving you some valuable cash. Some restrictions do apply. Here are the details:

Free shipping offer is valid only on qualified items. Eligible items are identified on their product page and may also be identified in your shopping cart. Shipping method will be selected by Rock Bottom Truck. Free shipping orders will be delivered via a standard ground shipping method selected by Rock Bottom Truck or our direct-ship manufacturers/fulfillment centers. Express shipping orders are not eligible for Free Shipping. Not available on international, Alaska, Hawaii, Puerto Rico or APO/FPO orders. Only standard ground shipping orders to residential and commercial addresses in the continental US are eligible for Free Shipping.

Rock Bottom Truck reserves the right to end or change this Free Shipping offer at any time.

LTL FREIGHT ITEMS

Some of the items we sell exceed the size limits for standard ground shipping and must be sent by truck or freight delivery. Please allow additional processing time and 7 to 10 business days for delivery once the item has been shipped. A carrier representative may call you to schedule a convenient time to deliver your item. Someone over the age of 18 may be required to be present to sign for the delivery and ID may be required for verification purposes.

Please be aware that your order will be delivered on a tractor trailer type vehicle and reasonable access needs to be available for the driver to safely maneuver his/her vehicle. The driver is only required to deliver your order to the Curb. Inside delivery is not available for your order. It may also be necessary for someone to assist the Delivery Driver to safely unload your order if a lift gate is not available or requested. If Access or Assistance is going to be an issue, you may request to pick up your order at the freight company's loading dock.

WILL I HAVE TO SIGN FOR MY PACKAGE?

For your security, we may require a signature for delivery. You may leave a signed note on your front door for the driver with special instructions. However, the delivery of the package is still at the discretion of the driver.

AFTER DELIVERY

If an item is delivered as a small package (UPS Ground, FedEx Home Delivery, US Mail) - please refuse delivery if visibly damaged. If there is concealed damage that is revealed upon opening your item, please send an email with pictures of the damage to yourfriends@rockbottomtruck.com to arrange for replacement / return. DO NOT INSTALL A DAMAGED ITEM or a kit that is missing any components as installation voids your claim. Damage should be reported to us no later than 48 hrs after receipt of the shipment. Expect a response within 1-2 business days.

If an item is delivered as a freight delivery (truck delivery typical of large items) - open and inspect your item before signing for it and refuse delivery if excessively damaged. If there is minor damage, we may provide a partial refund to you instead of returning/exchanging. If the damage is unacceptable, DO NOT SIGN FOR AND/OR INSTALL THE DAMAGED ITEM or a kit that is missing any components as delivery acceptance or installation voids your claim. Please document and send an email with pictures of the damage to yourfriends@rockbottomtruck.com. Damage should be reported to us no later than 48 hrs after receipt of the shipment. Expect a response within 1-2 business days.

30 Day Return & Exchange Policy

The customer is responsible for confirming that the manufacturer part number is the correct fitment for their vehicle.

Depending on the terms, condition and/or special order status of the item, a restock fee may apply.

Step 2: Receive return authorization response and instructions via email
Step 3: Pack the product securely in its original packaging with all components

Why shop anywhere else? With Rock Bottom Truck's Best Price Guarantee, shop confidently knowing you are receiving the best product, for the best price, with the best service and support.

If you find an online retailer listing the same in-stock item at a lower price, including freight costs, Rock Bottom Truck will match or beat that price for you.

This pricing policy is not retroactive and the listing retailer must be authorized to ship the order in the United States.

Comparison shopping listings do not qualify for our Best Price Guarantee. Listings must be from websites or retailers that directly sell the items.

Rock Bottom Truck reserves the right to deny any price request, which may include items that ship LTL, discontinued and/or special order items.
