Custom Engine Parts Manufacturing — OEM & ODM Services
Can't find the part you need in our catalog? We manufacture custom diesel engine components based on your drawings, samples, or specifications. From one-off prototypes to full production runs.
Customization Options
Choose the approach that best fits your needs.
Drawing-Based Custom
Provide technical drawings (CAD, PDF, or DXF) and we manufacture parts to your exact specifications. Ideal when you have precise dimensional requirements.
Sample-Based Custom
Send us a physical sample and we will reverse-engineer it with full dimensional analysis. Best for parts where original drawings are unavailable.
Full Custom Development
From concept to finished part — our engineering team works with you to design and develop new components tailored to your application.
What We Can Customize
Our custom manufacturing covers a wide range of engine components.
- Cylinder liners and liner kits
- Pistons and piston rings
- Crankshafts and camshafts
- Cylinder heads and engine blocks
- Fuel injection pumps and injectors
- Gaskets and seals (custom dimensions)
- Brackets, mounts, and adapters
Our Custom Parts Process
A transparent, step-by-step workflow from inquiry to delivery.

Quality Assurance
Every custom part undergoes the same rigorous 4-stage quality control process as our catalog products. From raw material inspection to final pre-shipment verification, we ensure every component meets your specifications.
Our quality team provides dimensional inspection reports, material certificates, hardness test results, and — upon request — video inspection of finished parts before shipping. We stand behind every part we produce with our standard 12-month warranty against manufacturing defects.
For custom parts, we also perform first-article inspection (FAI) on initial samples and in-process checks during bulk production to maintain consistency across your entire order.
