King AM-Series Main Bearing Spacers

King AM-Series main bearing spacers are standard, aluminum-based parts designed for passenger cars with low-to-medium engine loads. They're sold as spacer sets for specific swaps, like adapting a Chevy 350 crankshaft into a 400 engine block, providing reliable, cost-effective, environmentally-friendly performance with excellent embeddability to protect crankshafts.

Key features:

* Material: Standard aluminum-based (Alecular) alloy, softest in King's line, ideal for everyday driving
* Performance: Good embeddability to absorb small particles, preventing crank journal scoring, and durable for typical use
* High-precision manufacturing for consistent thickness, ensuring uniform load distribution
