Some of the diesel parts available for sale on TamerX.com will require that you return your core (i.e., your old part) to us. In these cases, it will be clearly noted on the product detail page just below the price of the part.

Customers are responsible for the cost of shipping their cores to us unless a prepaid UPS return shipping label has been purchased when ordering your part.

I agree to return the core component of this product within 30 days from the purchase date. I understand that there will be a core charge hold on my credit card that will be cancelled after TamerX.com has received your core. If I do not return the core within 30 days, the core charge will be applied to my credit card.
