K1 Technologies Rods and Crankshafts

K1 Technologies strives to bring customers a high-quality connecting rod at an affordable price, while providing world-class customer service.

What Sets Us Apart

K1 Technologies produces "RACEREADY" rods and cranks at very affordable prices. Their connecting rods and crankshafts are a cut above the average imported rod. They are made to specific 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. K1's unique design, which is original to the K1 Technologies line of connecting rods, saves weight without sacrificing strength. They use ARP bolts exclusively.

Quality and Materials

Premium 4340 steel is used to manufacture all of K1s connecting rods and crankshafts. Bearing bore tolerances are held to +/-.0001". Bronze bushings allow for a full-floating pin. Press-fit pins are available on some rod sizes.


All of K1's crankshafts are made from 4340 material; core hardened for increased tensile strength and fatigue life and are 100% mag particle inspected. Bearing surfaces are polished and nitrided for wear resistance. Before any finish work is done, rods are 100% mag particle inspected. ARP bolts are installed and tightened to exacting specifications prior to honing to insure accurate and repeatable bore geometry. All K1 Technologies connecting rods are honed in-house and sizes are held to some of the tightest accepted tolerances in the industry. Rods are weight-matched into sets and boxed, with the rotating, reciprocating and total weights noted for convenient use in the balancing process.
