What does '.025 Oversize' mean for these rod bearings?

This means the bearings are manufactured to be 0.025mm smaller in diameter than the standard size. This is necessary when the crankshaft journals have been ground down to this specific undersize during an engine rebuild to achieve the correct oil clearance.

What Hemi engines does this bearing set fit?

This set is designed for 5.7L Hemi V8 engines from 2003-2008 and 2009 onwards, 6.1L Hemi engines from 2005-2010, 6.4L Hemi engines from 2011 onwards, and 6.2L Supercharged Hemi engines from 2014 onwards, including Hellcat variants.

Do these bearings come with installation instructions?

While these bearings are designed as direct replacements for the specified Hemi engines, it is always recommended to refer to the manufacturer's installation guide or a professional mechanic for proper installation procedures and torque specifications.

Product Details

Already running a built Hemi engine? This rod bearing set is the next piece of the puzzle for a precise rebuild. These ACL bearings are made to the original equipment specifications for Chrysler 345 and 370 cubic inch (5.7L and 6.1L) Hemi V8 engines, but they come in a .025mm (0.001 inch) undersize. This is crucial when you've had your crankshaft journals ground down during a rebuild to ensure you get the correct oil clearance.

ACL has been a well-known name in engine bearings for a long time. They use a multi-layer material that's designed to handle the stresses of performance engines. The .025mm undersize means these are intended for use with crankshafts that have been machined to match this specific size, which is common practice in performance engine building to achieve optimal oil flow and bearing life. This set includes the bearings for all eight connecting rods.

When rebuilding your Hemi, getting the bearing clearances just right is critical for engine longevity and performance. These ACL bearings are a solid option for anyone looking to put their engine back together with precision components. Make sure to check your crankshaft journal dimensions to confirm they have been machined to the .025mm undersize before ordering.
