What material are these Manley connecting rods made from?

These Pro Series I-Beam connecting rods are forged from 4340 vacuum degassed steel alloy. This is a strong material chosen for its ability to withstand the high stresses found in performance engines.

Are these rods a direct replacement for my stock LS-1 connecting rods?

These rods are .025 inches longer than the stock LS-1 connecting rod and measure 6.125 inches in length. While they are designed for LS-1 engines and compatible vehicles, you should confirm that this specific length and the overall build specifications are appropriate for your engine's configuration.

Do these connecting rods come with bearings?

The manufacturer's description does not specify if bearings are included with this set of connecting rods. It is common for performance connecting rods to be sold separately from bearings, so you may need to purchase them as a separate item.
