Fits select 1993-2006 Mitsubishi Lancer Evolution (Evo 4-9), Eclipse, Eagle Talon, and Plymouth Laser models with the 7-bolt 4G63 engine.

Designed for high-output stroker builds, this Eagle 100mm crankshaft is manufactured from forged 4340 steel using a non-twist forging process for superior grain flow and structural integrity. Each unit is nitrided for increased surface hardness and features micropolished journals to minimize friction and wear in high-RPM applications.

To maximize strength, these cranks are engineered with .125-inch fillet radiuses. This design reduces stress concentrations at the journal corners but requires the use of narrowed or chamfered high-performance bearings for proper clearance.
