Molnar Technologies Engine Connecting Rod Set

Molnar Technologies Connecting Rod Sets: Race-Proven Performance

When it comes to engine connecting rod sets, few names carry as much credibility as Molnar Technologies. Founded by Tom Molnar — a connecting rod engineer with decades of hands-on experience at Oliver Rods and K1 Technologies before launching his own company — Molnar Technologies has built a reputation for delivering race-caliber connecting rods with the precision tolerances that serious engine builders demand.

Built from the Ground Up in 4340 Billet Steel

Every Molnar connecting rod set starts with a strong foundation. 4340 billet steel forms the core material, which is then heat treated to improve tensile strength. After heat treatment, the rods are shot peened to further improve durability and increase fatigue life, adding an extra layer of protection against the cyclical stresses of high-rpm operation. Critical rod dimensions are held to tolerances of +/- .0001 of an inch — among the tightest specs available in the performance and racing aftermarket.

All Molnar H-beam rod sets are fitted with precision-machined bronze bushings for use with floating wrist pin pistons, and every set includes high-quality ARP2000 cap screws as standard hardware — not as an upgrade. Unlike 8740 material hardware, ARP2000 bolts do not require replacement at every engine rebuild, making these sets a smart long-term investment for repeat builds.

Standard, Power Adder, and Power Adder Plus Series

Molnar's lineup is designed to match the demands of the application. For naturally aspirated street and track builds, the standard H-beam rod sets deliver excellent strength-to-weight balance. For forced induction and nitrous builds, the PWR ADR™ (Power Adder) series features additional strength engineered specifically for turbocharged, supercharged, and nitrous-assisted engines — without adding unnecessary mass in areas that don't contribute to rod strength. Builders pushing the limits of extreme-boost or large-shot nitrous applications can step up to the Power Adder Plus series, developed in response to demand for rods capable of surviving very high boost superchargers, large-displacement twin-turbo setups, and massive nitrous shots.

Wide Application Coverage

One of the most compelling aspects of the Molnar connecting rod lineup is its breadth. The catalog spans an enormous range, from 3-cylinder personal watercraft engines to the Dodge V10 Viper, and includes coverage for popular platforms like GM LS/LT engines, Gen III Hemi, Ford 4.6L/5.0L Coyote, Chevy small block, and many more. Rod sets are available for both stock-stroke and stroker configurations, with options designed to accommodate smaller rod journal diameters to ease clearance issues in stroker applications and reduce rotating assembly weight. All Molnar rods are finished at the company's Michigan facility in the United States.
