Eminem once’t asked, “who’s got the rubbers?”

Apparently not Cummins, but we do.

ISX15 liners with 2 o-rings for double the protection. Sleep better at night knowing your rubber didn’t break.

🔧 Tired of repeated counterbore failures on your Cummins ISX15?

One of the biggest causes of dropped liners is microscopic liner movement. Over time, even slight movement between the liner and block can contribute to counterbore wear, eventually leading to liner height issues, head gasket failures, and expensive repairs.

We offer a permanent block improvement designed to address that problem.

Our process involves machining the top of the block and installing a precision repair sleeve with a smaller inside diameter. This creates a press-fit liner, helping eliminate the microscopic movement that contributes to counterbore wear.

Benefits include:
✅ Press-fit cylinder liners
✅ Helps reduce liner movement
✅ Helps prevent future counterbore wear
✅ Reduces the risk of dropped liners
✅ Can be performed with the engine still in the truck or with the engine removed

Building a new engine? We can also supply ISX15 blocks that have this upgrade already completed, ready for your next build.

If you’re planning an overhaul or want to improve the long-term durability of your ISX15, send us a message to learn more about this upgrade.

Build it once. Build it right.

New Service: Builder Assist Program

Do the work yourself. Let us handle the precision.

Not everyone wants to pay for a complete engine build—and many mechanics and owner-operators are fully capable of doing most of the work themselves. The challenge is having the specialized tooling and technical experience for the critical parts of the rebuild.

That’s where we come in.

We’ll travel to your shop and perform the precision operations that matter most, so you can confidently finish the rest yourself.

Our service includes:
✔ Counterbore cutting
✔ Counterbore measurement and shim selection
✔ Liner installation
✔ Piston and connecting rod installation
✔ Camshaft installation
✔ Timing gear assembly and engine timing
✔ Cylinder head installation
✔ Rocker arm installation
✔ Complete valve adjustment

Flat Rate: $3,000 + Travel

Counterbore Cutting: $1,000
(Counterbore shims billed separately.)

Once we’re finished, you can complete the remaining assembly at your own pace:
• Oil pan
• Front cover
• Turbocharger
• Intake and exhaust manifolds
• Fuel system components
• Radiator and cooling system
• Wiring and sensors
• Accessories, etc

This service is perfect for:
• Owner-operators
• Independent repair shops
• Fleet maintenance departments
• Anyone wanting to save thousands in labor while still having the most critical engine work completed by an experienced builder.

When it comes to diesel engines, the precision work is what determines whether your overhaul lasts 50,000 miles or 1,000,000 miles.

If you’re planning a rebuild and want professional help where it matters most, send us a message to discuss your project and schedule a visit.
