Description
Description
The Industrial Injection Torque Lock Injector Cup Kit is the proven solution for one of the most common failures on Cummins ISX15, QSX15, and X15 engines: leaking press-fit injector cups.
If you’re dealing with coolant in fuel on your Cummins ISX15, the root cause is often a loose factory press-fit injector cup. This kit provides a permanent fix by replacing the OEM sleeve with a threaded billet injector cup design.
