Eagle B12311L030 Rotating Assembly Kit balanced - 8-Cylinder 0.030

The Eagle B12311L030 is a complete balanced rotating assembly designed for 8-cylinder engines. Eagle Specialty Products engineers each rotating assembly as a matched, balanced unit, eliminating the time-consuming and costly process of individually sourcing and balancing crankshafts, connecting rods, pistons, and bearings separately.

Eagle rotating assemblies are a popular choice among engine builders — from weekend performance enthusiasts to professional race shops — because they deliver precision-matched components straight out of the box. The +0.030" overbore specification makes this assembly ideal for engine rebuilds where the block has been bored to accommodate worn or damaged cylinder walls.

Key Features:

• Complete balanced rotating assembly for 8-cylinder engines
• +0.030" overbore pistons for freshly bored engine blocks
• Components precision-matched and factory balanced for smooth operation
• Designed to reduce engine vibration and extend component life
• Saves labor time compared to sourcing and balancing individual components
• Manufactured by Eagle Specialty Products, a trusted name in performance engine building

This assembly is a go-to solution for engine rebuilders seeking a cost-effective, high-quality rotating assembly. Always verify bore size and stroke requirements against your specific block before installation.
