Speedmaster PCE234.1006.01 Compatible with Chevy SBC 350 Std Narrow Conrod Bearings (Large Journal & Large Radius Crank)

These Speedmaster connecting rod bearings are just what you need to freshen up your engine. Why? They use silicon aluminum bi-metal construction. Silicon aluminum is the choice for many of today's engine manufacturers because of its high fatigue strength and superior temperature threshold. Bearing wear is dramatically reduced and the fatigue strength is greatly improved.
