This is the crankshaft for the Mazda B2300. The crankshaft converts the pistons' up-and-down motion into the rotation that drives the transmission, and it must run true and balanced for the engine to be smooth. A damaged or worn crankshaft causes knocking, vibration, and eventually engine failure, so it is replaced during a rebuild. This one is forged steel with internal balance.
On fitment, the Mazda B2300 is the US-market gas pickup, a rebadged Ford Ranger with the 2.3L inline-4. The early trucks used the Ford 2.3L 'Lima' engine and the later trucks the 2.3L Duratec, which are different engines with different crankshafts, so confirm the engine code by VIN; the live FAQ states the listing is for the 2.3L in B2300 models from 1994 to 2001. Unlike the B2500, which spans a gas and a diesel engine, the B2300 is unambiguously the US gas engine.
On condition, the journal diameters listed (2.398 in main, 2.123 in rod) are the standard specs, so for a used crankshaft the actual measured journal diameters, straightness, and whether it is standard or reground undersize must be confirmed. The live page is honest that fitting a crankshaft is an internal engine job requiring full teardown, torque specs, and balancing, for experienced mechanics; that framing is kept, and the bearing clearances should be checked with plastigage and the bearing sizes confirmed.

Not sure which B2300 crankshaft you need? Call (240) 301-0095 with your VIN. Our team confirms the engine code and the measured journal sizes before your order ships.
Quality control for this part includes:
Engine code confirmed for your VIN before shipping
Main and rod journals measured
Straightness checked
Standard-versus-reground confirmed
Matching bearing sizes identified before purchase
Because this is a used internal engine part, we confirm the measured main and rod journal diameters, the straightness, and whether the crankshaft is standard or reground undersize, along with the matching bearing sizes. Fitting a crankshaft is an internal engine job requiring full teardown, bearing fit, torque specs, and balancing, so we route the install to an experienced mechanic.
