D Type Engine Shipping Delay Notice l Stirlingkit
March 17, 2026We would like to inform you of a delay in the shipment of the Lister D engine model.
During the final testing phase, we completed comprehensive performance evaluations of the engine. To further enhance its durability and long-term reliability, we have decided to upgrade the piston ring to a metal piston ring.
This improvement ensures better wear resistance and a more stable operating experience. However, it also requires additional time for production adjustments.
Free Upgrade – No Extra Cost
This is a free upgrade for all customers.
You will receive the improved version at no additional cost.
Updated Shipping Schedule
Due to this upgrade and the additional production adjustments required, the shipping schedule will be slightly delayed:
- Estimated delay: Approximately 1 month
- Estimated shipping time: Mid-April
Our Commitment
We understand that delays can be frustrating. However, we believe this decision is the right one to ensure you receive a product that meets a higher standard of quality and performance.
We sincerely appreciate your patience and understanding.
If you have any questions, please feel free to contact us at any time.
Thank you for your continued support.
