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 produces -RACEREADY- rods and cranks at very affordable prices. Our connecting rods and crankshafts are a cut above the average imported rod. They are made to our designs and are held to some of the tightest accepted tolerances in the racing industry. More attention is shown to finish work than comparable products. A wide variety of sizes and applications are available, from the Sport Compact sizes through Small Block and Big Block Chevy and Mopar, including some custom and specialty sizes. Our unique design, which is original to the K1 Technologies line of connecting rods, saves weight without sacrificing strength. We use ARP bolts exclusively.
