All internal engine wear surfaces become worn over time.
This is true for crankshaft journals, connecting rods, camshaft lobes, piston rings, bearings, etc.
When rebuilding a worn out engine, you'll need to replace them all to regain the engine's original performance.
Let's face it, Jeep's need all the power we can get.
