Engine Shipment Policy – Inspect Before Accepting

EMS is not responsible for any engine damage that occurs during shipping. Before accepting and signing your shipment, you must carefully inspect the pallet or crate for any visible damage. If there is any sign of damage that could have affected the engine, do not accept the shipment. Instead, refuse delivery and have it returned to EMS through the carrier. Finally, contact Susan at EMS to start the claims process. Always inspect your engine before signing the freight carriers Clear Delivery Recepit.

Important: The freight carrier is not automatically responsible for damages once the shipment is signed for. If you accept a damaged shipment, you take full responsibility for any damage, and neither EMS nor the carrier will be liable.

DISCLAIMER: EMS does not take any responsibility in the event that the BadAss Build short block is assembled and/or timed incorrectly by non EMS associates. Even though they are just four cylinder engines, they are more complex than one may think. We strongly encourage that if at any point that you or your mechanic are in doubt on how to proceed, please contact us to schedule a Facetime, WebEx, or Zoom consultation. Consultations are $75 per hour and can be scheduled by calling us at (423)500-4901.
