Additional Info

With many years in the field of designing, engineering and manufacturing connecting rods and crankshafts we will do our best to provide you with great products and world class customer service. We welcome your phone calls, comments, requests and certainly welcome the opportunity to be your company of choice when it comes to connecting rods and crankshafts.

Our Commitment 
We at K1 Technologies strive to bring our customers a high-quality connecting rod at an affordable price, while providing world-class customer service. We will treat our customers with respect, realizing that it is our privilege to be your source of connecting rods and crankshafts.

What Sets Us Apart
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.

Quality and Materials
Premium 4340 steel is used to manufacture all our connecting rods and crankshafts. We only use ARP fasteners, with ARP 2000 included standard and 625+ Custom Age bolts available as an upgrade. 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 connecting rods are 100% designed, finished and inspected in the USA.

Process
All of our 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, our rods are 100% mag particle inspected. ARP bolts are installed and tightened to our 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.
