K1 Technologies Chevrolet LS7 Crankshaft, 4.000 in. Stroke, 2.650 .in Main Journal, 2.100 .in Rod Journal, 6 Bolt Flange Type, Forged 4340 Steel.
K1 Technologies crankshafts are 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.
Manufactured from forged or billet premium 4340 steel ~ Engineered specifically for high-stress racing applications ~ Nitrided for improved strength and bearing life ~ Large fillet radii for improved strength ~ Straight hole oiling system for improved lubrication ~ Size tolerances held to +/- .0001 in.
K1 Technologies crankshafts offer world-class performance at an affordable price. Our crankshafts are made from 4340 forged steel and core hardened to reduce stress and optimize tensile strength. Each crank is designed with counterweights placed for optimal load reduction and ease of balancing.
