Engine & Performance Warehouse MS2216AL020 Engine Crankshaft Main Bearing Set 0.020" Undersize

The Engine & Performance Warehouse MS2216AL020 is a crankshaft main bearing set in 0.020-inch undersize, designed for use during engine rebuilds where crankshaft journals have been reground to the first standard undersize. This aluminum bimetal bearing set delivers reliable crankshaft support and wear resistance suited for OEM-replacement engine rebuilding applications.

Key Features:

• Aluminum bimetal construction — the relatively harder aluminum alloy provides excellent wear characteristics and close conformability with journal surfaces
• 0.020" (0.508mm) undersize — engineered for use with crankshafts that have been reground to the first standard undersize specification
• Complete main bearing set — includes all upper and lower bearing shells required for a full crankshaft main bearing replacement
• Manufactured to meet or exceed OEM dimensional and material specifications
• Precision-finished bearing bores for consistent oil film thickness and load distribution

The "AL" designation confirms aluminum bimetal bearing material, ideal for standard and light-duty rebuild applications. Always verify crankshaft journal diameter with a micrometer prior to installation to confirm 0.020" undersize is the correct specification for your application.
