K1 Technologies strive to bring their customers a high-quality connecting rod at an affordable price, while providing world-class customer service. 4340 steel is used to manufacture all of our connecting rods and crankshafts. We only use ARP fasteners, with the option of either 8740 or ARP 2000 material. Bearing bore tolerances are held to +/- 0.025 mm. Bronze bushings allow for a full-floating pin. Press-fit pins are available on some rod sizes. All of our crankshafts are made from 4340 material; core hardened for increased tensile strength and fatigue life and are 100% magna flux particle inspected. Bearing surfaces are polished and nitrided for wear resistance.
Before any finish work is done, our rods are 100% magna flux 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.Carrillo
