Construction & Design:

These connecting rod bearings are constructed using premium bearing alloys that balance strength and durability with excellent conformability. ACL employs advanced metallurgical processes to produce bearings that resist deformation and maintain dimensional stability under extreme engine conditions. The bearing shells feature a smooth surface finish to minimize friction and wear, while the undersize design (.75mm) allows for precise fitment during engine rebuilds where crankshaft journals have been machined.

The design ensures consistent oil film formation, critical for protecting the connecting rod journals and preventing metal-to-metal contact. This attention to detail in materials and manufacturing results in bearings that contribute to smoother engine operation and longer engine life.
