Description

The Sealed Power 4924MA engine crankshaft main bearing set is an OE replacement for Chrysler and Dodge big block engines from 1959 to 1974. Designed for 426 and 440 cubic inch displacement engines, it ensures reliable performance in classic passenger vehicles. This set is constructed with A-series bi-metal aluminum alloy, providing greater seizure resistance than tri-metal materials and reducing bearing wear.

They are made with silicon for greater surface hardness, ensuring durability and performance even under extreme heat and loads.
