Core must be sent to MTNTK Performance for credit. 

To order follow these 2 steps

1) Select proper cylinder and add to cart.  Place order.

2) Next, please compose an email to: orders@mtntkperformance and confirm if you are sending in a core or do not have a core. Pick the desired method of order fulfilment below and state which way you would like us to handle your order.

A - No core - We will send you another payment request for the core charge.  Once core charge is paid we will ship the cylinder.

B - You have a core - We will wait until the core is received and check if it is a usable core. Least expensive option.

C - Ship now send core later - We will send you a payment request for the core, once paid we will ship the cylinder.  You send the core in and when we confirm is a good core we will refund you the core price.

And remember we will also buy good cores even if you do not purchase a cylinder from us.  Call us or email with a casting number and a picture of the worst damage to the cylinder and we will let you know if it is a candidate to purchase!
