Core return & shipping information

$500.00 core deposit

This engine requires the return of your old engine block and cylinder head. A temporary waiver does not eliminate the core return requirement.

For this listing, the deposit may be waived for up to 15 business days when shipped directly to a licensed repair facility. If shipped to a private residence, the core deposit must be paid upfront.

Fraser arranges free core pickup. Your applicable waiver terms and return deadline will be confirmed during order verification.

Delivery to your shop or home

  • Commercial delivery: FREE
  • Residential delivery: $125.00
  • Free return pickup of your required core
  • Listed delivery estimate: 2–3 business days for eligible in-stock orders placed before 3 PM Eastern; exclusions apply

Stock and transit times are subject to confirmation. Your delivery estimate depends on engine configuration, order verification, destination and carrier scheduling.

Before you order

How do I order this engine?

Use the Buy Now button to open our order form. Include your vehicle year, make, model, VIN and SKU FEFGM37R-HD. Your order and payment must be verbally verified with Fraser before payment is charged.

Do I still need to return my old engine if the deposit is waived?

Yes. The waiver temporarily defers the core deposit; it does not purchase your old engine or remove the return requirement. Arrange your core return with Fraser within the deadline confirmed for your order.

Can I order without knowing my exact engine configuration?

Call 800-731-3177 and press 1 for Sales. Have your VIN ready so a team member can check the application and help you select the correct engine.
