What is the purpose of the extra oil clearance in this bearing set?

The extra 0.025mm (0.001 inch) of oil clearance allows for a slightly thicker oil film between the crankshaft and the bearing. This can help reduce friction and wear, especially in high-performance or heavily used engines.

Are these bearings suitable for a stock Hemi engine rebuild?

Yes, these standard size bearings with extra clearance are suitable for stock rebuilds and are often preferred for performance applications. They are designed to meet the demands of Hemi engines.

What is required for installing main bearings?

Proper installation requires meticulous cleanliness, the correct torque specifications for the main caps, and often specialized tools for handling and seating the bearings. Always refer to the service manual for your specific vehicle.

About this part

Product Details

You get a full set of main bearings with extra oil clearance in this kit, which means you can precisely set up your Hemi engine for optimal lubrication. This ACL set is designed for Chrysler 5.7L Hemi V8 engines from 2003-2008 and also fits the 6.1L Hemi V8 from 2005-2010. Getting the oil clearance just right is crucial for engine longevity and performance, especially when you're building or rebuilding a Hemi.

These bearings are standard size but feature an extra 0.025mm (0.001 inch) of oil clearance. This is a popular modification for performance builds or engines that might see harder use, as it allows for a slightly thicker oil film. This can help reduce friction and wear, particularly under high-load conditions. ACL is a well-known name in engine bearings, and this set is a solid option for anyone looking to get their Hemi engine's bottom end dialed in.

When installing main bearings, it's important to have the correct tools and to follow the manufacturer's specifications for torque and assembly sequence. Cleanliness is also paramount; any debris can compromise the new bearing surfaces. If you're unsure about the process, it's always best to consult a professional mechanic.
