What material are these connecting rods made from?

These Manley connecting rods are made from strong forged 4340 vacuum degassed steel alloy. This material is chosen for its durability and ability to handle high performance demands.

Are these rods suitable for a stock engine rebuild?

While these rods are built for high performance, they can be used in a stock engine rebuild if you are aiming for increased reliability or planning future upgrades. However, they are specifically designed to handle the stresses of boosted and performance-oriented MZR 2.3L DISI engines.

Do these connecting rods come with bearings?

This set includes the connecting rods themselves. It is recommended to purchase compatible rod bearings separately, ensuring they meet the specifications for your engine build and are compatible with these Manley rods.
