Cummins ISB and QSB Overhaul Kits | 3.9 L | 5.9 | 6.7
Cummins ISB and QSB Overhaul Kits comprise a collection of replacement components designed to bring an engine back to its factory condition. These kits generally include items like pistons, rings, bearings, gaskets, and seals. They serve to substitute parts that are worn out or damaged, ensuring the engine operates optimally.
In-frame Cummins ISB and QSB Overhaul Kits
These kits are intended for minor engine repairs and typically feature only the essential components needed to fix the engine without removing it from the vehicle. Commonly included in these kits are gaskets, seals, bearings, and other vital internal engine parts.
Out-of-frame Cummins ISB and QSB Overhaul Kits
These kits are for more extensive engine repairs and require the engine to be taken out of the vehicle for a complete overhaul. They usually encompass all elements found in the in-frame kits, along with additional items such as pistons, liners, and connecting rods.
