Hard fitment gate — engine code and serial number, not displacement alone:

This kit does not fit the 14.0L Series 60, which uses different cylinder kits.

Series 60 cylinder kits changed across the production run. Confirm your engine code against the list above and your engine serial number before ordering. If your engine code is not listed, contact us before purchasing — ordering the wrong inframe kit is discovered only after the engine is apart.

Conclusion:

This FP Diesel inframe kit rebuilds Detroit Diesel Series 60 11.1L and 12.7L engines using Detroit cylinder kit 23532555, with TLC liners and 2.50 mm top ring pistons. Verify your engine code and serial number first — Series 60 inframe kits are not interchangeable across the production run.
