Product Details

The ACL Bearings 5M909P-30 is a precision-engineered tri-metal main bearing set designed for Small Block Chevy (SBC) V8 engines including 267, 305, 327, and 350 cubic inch displacements from 1967-1998. This bearing set features a 0.030 inch (0.30mm) oversized crankshaft journal diameter, making it ideal for engines with machined or worn crankshafts that have been ground undersize.

Key Features:

  • Tri-metal construction with copper-lead alloy for superior durability and wear resistance
  • Duraglide series coating provides excellent friction reduction and heat dissipation
  • Softer bearing material protects crankshaft and engine block from excessive wear
  • Engineered with precise oil clearances to allow crankshaft to "float" on thin oil film
  • Complete main bearing set for all main journals
  • 0.030" (0.30mm) oversized for machined crankshafts
  • Compatible with large journal SBC engines

ACL main bearings are manufactured to exacting tolerances to prevent oscillations and excessive wear that can damage the crankshaft and other critical engine components. The tri-metal construction combines strength with the proper hardness characteristics to protect both the bearing surface and the crankshaft journal during high-performance operation.

Great price and fast shipping! Tech support helped me before the sale to make sure I was ordering the right part

Autoplicity got my air filters shipped next day after I placed my order. Cheap prices, and good customer is what they stand for. I will definitely be looking at their site in the future for my car needs. <br>

Web site has a lot of items without much description.

Had exactly what I was looking for at the best price on the net. Shipped next day. Fuel Pressure Regulator was as described and met my needs.

Great prices with fast shipping
