Factory-Spec Crankshaft Assembly for Subaru Boxer Engines ⚙️

This precision-balanced bottom-end core restores smooth power delivery and protects your engine under daily driving or performance use. Built to OEM geometry, it ensures exact oiling, journal hardness, and balance for long life and quiet operation.

Why you need it 🔧

The crankshaft converts the pistons’ up-and-down motion into clean rotation to drive the flywheel, timing, and accessories. Correct journal sizes and oil passages maintain oil film, cut friction, and stabilize bearing temperatures. A worn or out-of-round unit hurts power and fuel economy.

How it works 🛠️

Rod journals sit offset from the main axis to turn linear force into torque. Main journals ride on pressurized oil in the block bearings. Counterweights cancel boxer engine vibrations, while keyways and reluctor/timing drives keep ignition and timing precise.

What happens if it fails 🚨

Symptoms include knock at idle, metal glitter in oil, low pressure, misfire, harsh vibration, and stalling. Continued use risks spun bearings, thrown rod, or full engine seizure.

Installation tips 🧰

Mic and plastigage all journals, match new bearings, follow torque sequence, use assembly lube, verify endplay, and prime the oiling system before first start. Ideal for rebuilds seeking OEM smoothness and reliability.
