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.
1. What’s Upgraded
Free Upgrade for All Orders
All shipped engines will now come with metal piston rings installed, replacing the previous fluororubber O-rings for improved durability and performance.
2. Pre-Order Bonus
Free Gifts for Pre-Order Customers
All customers who placed orders during the pre-sale period will receive the following gifts for free:
- Water container
- Fuel funnel
- Fuel dropper (plastic bottle)
These will be included in the shipment package.
⚠️ Orders placed after the first batch has been shipped will not include these gifts.
3. Shipping Priority
First Come, First Served
The first batch is limited in quantity. Orders will be shipped based on purchase time — earlier orders will be fulfilled first.
4. Shipping Timeline
Estimated Shipping Schedule
We are currently accelerating production and working overtime to fulfill orders:
- A small batch is expected to be completed within this month
- All orders are expected to be shipped by mid-April at the latest
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.
