core return policy


Core Return:
​To keep our prices low, we sell our products based upon a rebuildable core being returned to us. This is a temporary deposit that is withheld until a rebuildable damaged unit is returned to our facilities.
Picture

Core Credit Criteria: 
To receive a full return of your core deposit, we must receive your rebuildable core within 30 days of shipping our product(s). Any extension must be approved by a sales manager. Be sure to ask one of our service professionals if you have any questions regarding the condition of your core. The core returned must be rebuildable to receive a full credit of the core charge.

Core Refund:
Orders are typically refunded back onto your credit card within 1-3 weeks after the core arrives at our facility. Check orders will be mailed back. Please call one of our service professionals to inquire about your core return.

Core Return Shipping:
All of our products are shipped with a "Bill of Lading" which will contain a return address for shipping core returns. Individuals or the certified ASE shop can return the core with the delivery driver or make shipping arrangements. If you have any comments or concerns in regards to shipping core returns, feel free to contact one of our service professionals.

Bad or Missing Core:
If there is no core or if the core is known to be unbuildable, we can simply add the core charge amount to the total invoice.

Sending the Core First:
We will gladly receive your core first allowing us to verify that it is rebuildable then only charge our customers for the purchase of our product(s) and one way shipping. This can greatly save our customers in many instances as this transaction would not require a core deposit once the shipped core was verified rebuildable.
