Molnar LS Rods

Molnar LS Rods

Molnar LS rods are premium H beam connecting rods 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 LS connecting rods are fitted with highly durable premium bronze bushings for use with floating pin type pistons. Each set of Molnar LS con rods includes proprietary ARP2000 fasteners made by ARP to Molnar specifications, lubricant and installation guidelines.

All Molnar LS rods are finished in the United States at the Molnar Technologies shop in Michigan. All 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.
