Molnar Technologies H Beam Subaru EJ25 connecting 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 which also increases fatigue life. All Molnar EJ25 rods are fitted with highly durable premium bronze bushings for use with floating pin type pistons. Each rod set for the EJ25 turbo and non turbo engine includes ARP fasteners, lubricant and installation guidelines.
All Molnar EJ25 conrods 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. These rods are an excellent upgrade component for street, high performance and racing EJ25 engines.
