S14 EVO3 Billet Crankshaft by 5150 AutoSport F35 000 -Due to the challenges in sourcing the S14B25 Evo3 2. 5L crankshaft from BMW, we have decided to offer a 4340 billet steel crankshaft at a comparable or lower price than BMW. The dimensions are identical to the BMW Evo3 specifications, allowing you to use factory main and rod bearings, factory pistons, and factory connecting rods.
