What is the difference between standard and undersize bearings?

Standard size bearings are used when the crankshaft journals are in good condition and have not been machined. Undersize bearings are used when the crankshaft has been ground down to remove damage or wear, and they are sized to match the amount the crank was turned down.

Do I need to measure my crankshaft before ordering?

Yes, it's always a good idea to measure your crankshaft journals to confirm they are within the standard size specifications before ordering bearings. This ensures you get the correct fitment for your engine rebuild.

What else might I need for this engine rebuild?

When rebuilding an engine, you'll typically need a full gasket set, oil pump, oil filter, and potentially piston rings and rod bearings depending on the scope of your rebuild. Always refer to your vehicle's service manual for a complete list.

Product Details

You get a full set of crankshaft main bearings in this kit, which means one box handles the critical bottom-end rebuild for your V8 351C or 351CJ engine. These bearings are what the crankshaft rides on inside the engine block, and they're essential for smooth operation and proper oil pressure. If you're rebuilding your engine or dealing with worn bearings, this set from ACL is a solid option.

ACL has been making engine bearings for a long time, and they build these to handle the demands of a V8. They're made to the correct specifications so they fit right into your Ford's main caps. Proper bearing clearance is key for oil flow and longevity, and this set is designed to provide that when installed correctly. This is a standard size set, meaning it's for a crankshaft that hasn't been machined undersize.
