Product Description
K1 4.000" LS Stroker 24x Forged 4340 Crankshaft
Fits 1997-2013 LS-Based Engines when using Gen 3 PCM or Aftermarket EFI
K1 Technologies crankshafts offer outstanding performance at an affordable price! This 24x LS stroker crankshaft is made from 4340 forged steel, core hardened and nitride hardened for optimum strength, increased fatigue life and minimized distortion. To help ensure consistent quality each crankshaft is magnetic particle tested to ensure it is free of flaws and journal tolerances are held to +/- .0001” to ensure consistent bearing clearances. A .125" fillet radii on the journals vastly increases strength and stiffness over factory crankshafts, and straight-hole oiling improves lubrication.
