Core returns

Ship us your oil rail core

Returning your old 6.0L Power Stroke oil rails gets your refundable $400 core deposit back. Follow the shipping steps below, then let us know your core is on the way so we can watch for it.

How it works

Three steps to your core refund

Step 1

Order with the core option

Buy your rails with the “Prepay refundable core (+$400)” option — or just ship your old core in if you already ordered.

Step 2

Ship us your old core

Pack your old oil rail and send it to our cores address below. Return shipping is on you; we recommend tracked, insured postage.

Step 3

We inspect & refund

Once your rebuildable core arrives and checks out, we refund your $400 core deposit to your original payment.

Before you ship

Shipping requirements

  • Send only a rebuildable 6.0L Power Stroke oil rail core — no cracked, stripped, or welded rails.
  • Drain residual oil and cap or bag the rail so it doesn’t leak in transit.
  • Include a note inside the box with your name and order number so we can match your core to you.
  • Pack it securely — a sturdy box with padding — to prevent shipping damage.
  • Use a trackable, insured shipping method. Return shipping is the customer’s responsibility.
  • Ship within 30 days of receiving your remanufactured rails to qualify for your $400 core deposit refund.
