Free shipping is available on most orders within the lower 48 states for orders totaling $150 or more. Simply select the free shipping option during checkout. Even though expedited shipping is not free we may still be able to provide discounted expedited shipping if available. Some items may require freight shipping.


The majority of orders containing in stock items will ship the same day if placed on a weekday before 2PM MST / 4PM EST. Orders requiring additional verification (follow-up, security concerns, incorrect information, etc.) may need additional processing time. We will contact you with an estimated shipping timeframe if an item is found to be out of stock. These estimated dates are not guaranteed and are subject to change periodically. Our customer service representatives monitor backorders as best as they can to ensure your order ships as soon as possible.


The delivery time of your package primarily depends on the shipping carrier and the service level selected. While our website automatically quotes a timeframe in which a package may arrive during checkout, keep in mind that these are simply quotes from the service provider and may not take into account processing, packaging, and/or drop-shipping location variances. When selecting the shipping method for your package, please keep in mind that most carriers do not work on weekends or major holidays. We cannot control the shipping method on some items (even if the website allows a selection) as this may be controlled by the company drop-shipping the product. When carriers quote shipping days, they are referring to business days. Business days are defined as Monday through Friday, with the exception of holidays observed by the parcel carriers. As a general rule, transit times is usually 3-5 business day, unless an expedited service has been selected.


If an order is placed for a product that is found to be out of stock, we will contact you to verify that the estimated shipping timeframe works for all parties and ship the item as soon as it becomes available if accepted. JST Performance reserves the right to split your order into multiple shipments without notification in an attempt to try and get your products to you sooner. Orders are normally only split automatically if both orders qualify for free shipping.


We do not currently offer international shipping of physical items, unless the order has been verbally cleared by our sales team. If you are interested in placing an international order, please contact us at for a quote on international shipping. Custom tunes do not require shipping and should be available for purchase through the website without prior clearance.


Shipments going to an APO or PO Box will default to ship via USPS as the shipping carrier. Please be aware that the United States Postal Service (USPS) has size restrictions on shipments going to APO’s and PO Boxes. If you have a large item needing to ship to a postal box please contact one of our customer service representatives to look at available options. If you choose to have your APO or PO Box shipment sent via a different carrier, we suggest verifying the delivery possibilities with that carrier before placing the order. If a package is deemed undeliverable by a carrier that cannot delivered parcels to your post office box or APO the buyer will be responsible for all freight charges and fees associated with the shipment.


If you wish to have your item(s) shipped to an address other than your billing address, please be aware that your order may require additional verification and may be subject to processing delays. We recommend allowing extra time for order fulfillment when shipping to an alternate address. If you have any questions about your order verification please feel free to contact our customer service department.


If your shipment becomes damaged or lost in transit, please notify one of our customer service representatives immediately. Do not discard any boxes or packaging materials that were included with the shipment. In order to fully process a damage claim, all original products and packaging materials must be provided. JST Performance is not liable for damage claims that are denied due to customer negligence.

Customer is responsible for inspecting all shipping containers prior to accepting shipment, especially larger items and/or carbon fiber components that may be damaged in transit. Damaged items accepted by the customer may not be able to be replaced by the manufacturer after acceptance.
