What is the difference between standard and undersize bearings?

Standard bearings are meant for a crankshaft that is at its original factory size. Undersize bearings are used when the crankshaft has been machined down to correct for wear or damage. These are standard size, so they require a crankshaft that hasn't been machined undersize.

What does 'tri-metal overlay' mean for these bearings?

Tri-metal construction typically involves three layers: a steel backing for strength, a copper-lead alloy for heat dissipation and embeddability, and a thin overlay of babbitt (a soft alloy) for conformability and wear resistance. This design is common in performance and OEM bearings for its durability.

Do these bearings come with new rod bolts?

This product is a set of connecting rod bearings only. It does not include new connecting rod bolts or nuts. You will need to source those separately if your rebuild requires them.

About this part

Product Details

200,000 psi tensile strength puts these ACL connecting rod bearings well above stock hardware. When you're rebuilding the engine in your Hyundai G4KC (Theta) 2359cc or Kia G4KL (Theta II) 1998cc, the bearings are a critical component. These are standard size bearings, meaning they're meant to be installed on a crankshaft that hasn't been machined undersize. They help ensure proper oil clearance between the connecting rod and the crankshaft, which is essential for engine longevity.

ACL is known for making well-built engine components, and these bearings are no exception. They use a tri-metal overlay construction, which is a common and effective design for handling the high loads and temperatures found in an engine's bottom end. This construction helps them resist wear and maintain consistent oil film even under demanding conditions. If you're doing a full engine rebuild or just replacing worn bearings, these are a solid option to get your engine running smoothly again.

This set includes bearings for all the connecting rods in your engine. Always refer to your vehicle's service manual for specific installation procedures and torque specifications to ensure a proper rebuild.
