What is a Core?
Many stock replacement parts such as turbos, injectors,
injection pumps, and high pressure oil pumps have a
core charge that is associated with the new replacement
part. You must return the old part to receive a refund
on the core charge. All cores must be like for like
and include all parts and pieces that were received
on your new replacement product.
Core Return Label
The core return label is a new option offered by Thoroughbred
Diesel to customers that buy products that have a core
charge. For a small fee Thoroughbred Diesel will send
you a core return tag either to your email or right
to your mail box. This will save you money on the return
shipping and will make sure your cores get returned
correctly. The label will be insured to protect your
core. This will make it a complete hassle free process.
Only available for the 48 contiguous states. If you
have any questions on it contact firstname.lastname@example.org.
No upfront Core Charge
No upfront Core Charge Thoroughbred Diesel has implemented
a policy on many products that eliminates the upfront
core charge at time of purchase reducing out of pocket
expense to the consumer on some products. On parts that
are not charged core you will have 14 business days
from the time of receipt of the product to get the core
back to Thoroughbred. You will be sent a pre-paid shipping
label separate through email. If you have any problems
PayPal & All Other Non-Credit Card Orders
All non-credit card orders, such as PayPal, and eBay
will require that we have a credit card on file on orders
with no core value. The on file credit card will not
be charged unless the core is not returned in the specified
time frame. A Thoroughbred Diesel Sales Agent will contact
you to obtain a credit card for your order.
Core Physical Condition
All cores must be in re-buildable condition to receive
a full refund of the core charge. There are some conditions
that you will not receive full credit. On these conditions
it is up to the manufacture on the amount of credit
