What does '0.010 inch undersize' mean for these bearings?

This means the bearings are designed to fit a crankshaft that has been machined down by 0.010 inches. This is a common practice during engine rebuilds to clean up worn crankshaft journals.

Are these bearings compatible with all 4.0L Jeep engines?

This set is specifically for the AMC/Jeep 4.0L engine and fits the listed Jeep Cherokee, Comanche, Grand Cherokee, and Wrangler models from 1991-2006. Always verify your specific engine and vehicle fitment.

What else might I need when installing main bearings?

When rebuilding an engine, you'll typically need new engine oil, an oil filter, and potentially main bearing cap bolts if yours are stretched or damaged. It's also crucial to ensure the crankshaft journals are clean and within the specified tolerance.

About this part

Product Details

This Clevite main bearing set is 0.010 inch undersize, meaning it's designed for crankshafts that have been machined down by 0.010 inches during an engine rebuild. These bearings are built for the AMC/Jeep 4.0L engine found in a range of Jeep vehicles from 1991 through 2006.

Main bearings are critical for supporting the crankshaft and ensuring it spins smoothly within the engine block. When rebuilding an engine, especially one with a lot of miles, it's common to have the crankshaft ground undersize to clean up any wear. This set from Clevite is well-built to handle the demands of the 4.0L inline-six, helping to restore proper oil clearance and reduce friction for a healthy engine.

This set includes the main bearings needed for a complete engine rebuild on your Jeep. Ensure you have the correct crankshaft journal size before ordering, as these are specifically 0.010 inch undersize.
