King Engine Bearings CR 819CP0.25 Connecting Rod Bearing Set 0.25mm Oversize Tri-Metal

The King Engine Bearings CR 819CP0.25 is a connecting rod bearing set engineered for General Motors 250, 273, and 300 16-valve engines. Manufactured by King Engine Bearings — a globally recognized leader in precision engine bearing technology — this set delivers reliable performance for medium-load engine applications.

These bearings are constructed using a tri-metal, copper-based material equivalent to SAE-794, a time-tested bearing alloy that provides an excellent balance of strength, wear resistance, and conformability. The tri-metal design consists of a steel backing, a copper-lead intermediate layer, and a lead-tin or lead-indium overlay, offering superior load-carrying capacity and embeddability compared to bi-metal alternatives.

Key Features:

• Tri-Metal Copper-Based Construction — SAE-794 equivalent material for proven durability
• Medium-Load Engine Rating — Suitable for standard performance General Motors engines
• +0.25mm Undersize — Designed for use with journals ground 0.25mm (approximately 0.010 in.) undersize
