Our 4340 forged crankshafts are heat treated to increase tensile strength, shot peened to increase fatigue life, nitrided for wear resistance and 100% mag particle inspected to ensure against cracks. Molnar Technologies has been one of the leaders in the GEN III Hemi platform. These forged cranks are designed to hold up and have proven it time and time again. Made to fit 5.7L, 6.1L, 6.4L or 6.2L HEMI engine block.
*The 5.7L Eagle, 6.2L Hellcat, and 6.4L Apache require a crank spacer.  

Sizes are held to the tightest tolerances you'll find in the racing industry!
