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.
