What does it mean for these bearings to be undersized?

These bearings are undersized by 0.00079 inches (0.020mm). This means they are intended for use when the crankshaft journals have been machined down (ground) during an engine rebuild to ensure a proper fit and oil clearance.

What is the primary function of connecting rod bearings?

Connecting rod bearings sit between the connecting rod and the crankshaft. Their main job is to reduce friction and wear by providing a smooth, low-friction surface for the rotating crankshaft, allowing the connecting rod to pivot freely.

Do I need any special tools or supplies for installation?

Yes, proper installation requires specific tools and supplies. You'll need a torque wrench to tighten the connecting rod bolts to the manufacturer's specifications, and assembly lube is essential to lubricate the bearings and crankshaft journals before initial startup.

Product Details

Already running a built G4KC engine? This connecting rod bearing set from ACL is the next piece of the puzzle. These bearings are crucial for keeping your engine running smoothly by providing a low-friction surface between the connecting rod and the crankshaft. When you're pushing your engine harder, especially after modifications, having a well-built set of bearings like these is essential for reliability.

This set is undersized by 0.00079 inches (0.020mm), which is important if your crankshaft has been ground down during a rebuild. ACL is a well-known name in engine bearings, and this set is made to handle the demands of performance engines. They are built with materials that offer good wear resistance and maintain their integrity under high loads and temperatures, which is exactly what you need when you've got the headers on and are looking to complete the exhaust system build.

When installing these bearings, make sure to follow the manufacturer's torque specifications and use the correct assembly lube. It's always a good idea to check your crankshaft journals for any imperfections before installation to ensure these new bearings perform as they should.
