4.6L & 5.4L Engine Rod Bearings
If you're building a high-level competition engine, you'll definitely want to check out Sealed Power CH-Series rod bearings 8-7250-CH. They were developed in the trenches in NASCAR and Pro Stock competition, so you know they're tough. They're built on premium 1020AK steel backings and overlaid with Sealed Power's super-duty H-14 alloy. That's covered with a nickel barrier, followed by a thin lead-tin-copper overplate. However, unlike other performance bearings, there is no flash tin layer on top of that. That's because Sealed Powers engineers have determined that such a layer can actually move around under high performance conditions, sometimes resulting in undesirable consequences.
