This is a stock Subaru Wrx crankshaft as it not cross drilled, does have the new induction hardening process that to all of its crankshaft, and thrust main on 3rd position. As far I can tell, the rods were not re-balanced after they resized and their bolts replaced. This crankshaft has been re-done.
010 under, just for the process and regrinding of crankshaft itself. This one was done in a short cycle that is commonly to crankshaft want hardening process the surface material of it. I have included some close up photos of the crankshaft counter weights to show that this has been re-balanced after it was re-ground for nitrating.
I am including the set of rods and rod bearings that are for newly sized crankshaft. What I mean by redone is that the crankshaft was re-ground to proper resizing before being sent nitrating process. As a per-caution, I would uninstall the bearings and clean everything before installing this into engine block. As far I could tell the rods have been resized and new rod bolts installed on them.
The only part numbers that I could find on front counter weight of crankshaft is 1RCBB zzzz f a. Up for offer your consideration is a re-manufactured Subaru Wrx crankshaft, resized connecting rods, and set of rod bearings. The parts were described to me as being from a Subaru Wrx and nothing else was said about car it came.
The bearings are new and have been installed into rods.
