Molnar Technologies H Beam 400 B Engine 450 Stroker Connecting Rods

Molnar Technologies H Beam 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 which also increases fatigue life. All Molnar connecting rods are fitted with highly durable premium bronze bushings for use with floating pin type pistons. Each rod set includes ARP 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.

Eagle 4340 Steel H beam rods are manufactured from a TWO-PIECE FORGING. The forging process forces the grain into the shape of a connecting rod, resulting in a superior fatigue life. The rod cap is forged separately so that the grain runs perpendicular to the load forces, which strengthens the rod.

• Installation instructions, torque specs and bolt lubricant included
• ARP 8740 Capscrews are included, ARP 2000 bolt upgrade available at an additional cost
• Silicon bronze bushings installed for use with floating wrist pins
• Heat treated
• Packaged in weight matched sets
• Certified 4340 steel, vacuum degassed to remove impurities
• Each forging is X-rayed, sonic tested and magnafluxed to insure quality
• Shot peened to stress relieve the metal
• Precision Alignment Sleeves positively locate the rod cap, maintaining big end bore size and eliminating cap walk.
