This Eagle forged 4340 steel crankshaft for Chrysler RB engines features a 4.150" stroke and is produced from a non-twist forging with .125" fillet radiuses for superior strength. The journal surfaces are nitrided and micropolished; chamfered or narrowed bearings are required for the fillet radiuses. Built to meet demanding applications, the crank compresses robust forging and surface treatments into a serviceable replacement.
