Quality Molnar Technologies connecting rods and crankshafts are intricate components for a performance or race engine. Speedfactor Ltd is proud to be associated with Molnar Technologies who have over 30+ years experience in the design, manufacture and exceptional finish quality for crankshafts and H beam billet conrods.
Designed with target horsepower and torque requirements for different engines, means the rods are produced with different target weights, conrod beam widths and bolt dimensions. They are either manufactured in a lightweight normally aspirated connecting rod form or in a heavier H beam section with longer rod bolts, for engines with supercharged or turbocharged induction.
Molnar technologies H beam connecting rods feature state of the art materials, manufactured from 4340 billet material, heat treated to increase tensile strength and are shot pened to increase fatigue life. All rods have a wear resistant bronze small end bushes for long wrist pin life.
All rods are fitted with ARP 2000 series Asymmetrical rod bolts and offer some of the closest tolerances in connecting rod accuracy in the market place today!
Reliability, strength at an affordable price!
