Molnar Technologies H Beam BBC rods are machined from billet 4340 steel, and then heat treated to provide improved strength. To make the rods even stronger, they are shot peened to increase fatigue life.

Each rod set includes ARP2000 fasteners, moly lubricant and installation guidelines.
All Molnar rods are finished in the United States at the Molnar Technologies shop in Michigan. Critical rod dimensions are are held to very precise tolerances of +/- .0001 of an inch, which is the tightest tolerance you will find in the performance and racing aftermarket.
