Описание товара:
Коленвал SUBARU 12200-AA390 EJ207 Черный.
Самый крепкий оригинальный коленьчатый вал от Subaru.
The '430 crankshaft from Subaru is their latest and greatest factory EJ crankshaft. The crank is nitride treated to be extremely hard and reduce the chances of wear and damage from foreign material. Through nitriding, surface hardness is doubled on the Rockwell scale, and fatigue life is increased by 25 percent. The dark finish is due to the temp and duration of processing for a deeper hardness. Rebuild your motor using Subaru's finest.

Nitride treatment hardens the surface of the crank, which prevents scoring caused by a piece metal getting stuck between the bearing and the crank.

By increasing the hardness of the crankshaft surface, any material which gets caught between the new surfaces is simply ground down and filtered out through the oil, potentially preventing bearing failure.
