Molnar Technologies H Beam Mopar connecting rods for the B, RB and Gen2 Chrysler, Dodge and Plymouth engines are machined from billet 4340 steel, and then heat treated to provide improved strength. To make the rods even stronger, they are shot peened which also increases fatigue life.

Each rod set for the Big Block Mopar engines includes ARP2000 fasteners, lubricant and installation guidelines.
