Cylinder Exchange

We have cylinders waiting so you don't have to.

Millennium Technologies’ Core Exchange Program is designed for accelerated turnaround on our OEM size plated cylinders. Millennium stocks thousands of cores across various applications so we can help you get back in action with minimum downtime.

How It Works:

Millennium Technologies’ Core Exchange Program requires that a customer sends in their cylinder in exchange for a Millennium Technologies core cylinder. Customers have two options when utilizing this program:

  • Customers can request that a core cylinder is shipped out prior to Millennium receiving the customer’s core cylinder. This option will apply a Core Charge to the customer’s order.
  • The second option the customer has is to send in their core cylinder to Millennium Technologies and have it exchanged upon receiving and inspection.

Acceptable Cores

Cylinders for Millennium Technologies’ Core Exchange Program must be inspected and met within the following criteria to qualify as an acceptable core for exchange:

  • No detonation on the cylinder.
  • No broken skirts on the cylinder.
  • No porting within the cylinder.
  • No sleeves installed (cast iron, aluminum, or other)
  • Cylinder must be OEM size (no overbores).
  • The cylinder being sent in for exchange must be the same type of cylinder that is being sent out from Millennium Technologies. For example, a KTM 250 cylinder will not be accepted for a Yamaha 125 cylinder regardless if it meets the rest of the criteria mentioned above.

Millennium Technologies maintains a expansive cylinder core inventory, but we highly recommend giving a call to one of our sales technicians before utilizing any of the Core Exchange Program options to ensure that the cylinder you are looking to exchange is in stock as some cylinders are rare and come in high demand. Please have your casting number and bore size information ready when you call. If a cylinder core is unavailable at the time of request, Millennium Technologies can always replate your cylinder within our regular turnaround time. Rush service is also available. In either case, the remanufactured cylinder you receive will perform as well or better than a new one and will carry a LIFETIME WARRANTY.
