What materials are these connecting rods made from?

These Manley Pro Series I-Beam connecting rods are available in either forged 4340 or 300M vacuum degassed steel alloys. Both materials are selected for their high strength and durability under demanding engine conditions.

Do these connecting rods come with bearings?

The manufacturer's description does not specify if bearings are included with this connecting rod set. It is recommended to check the product packaging or contact Manley Performance directly for confirmation.

Are these rods suitable for a stock engine rebuild?

While these rods are very well-built and some versions are NHRA legal for racing, they are primarily designed for performance and high-stress applications. For a standard stock rebuild, you might consider a different rod series unless you plan to significantly increase horsepower.
