Molnar LS1 Connecting Rods

Molnar Technologies H Beam LS1 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 GM LS connecting rods are fitted with highly durable premium bronze bushings for use with floating pin type pistons. Each rod set for the LS engines includes ARP fasteners, lubricant and installation guidelines.

All Molnar LS, LS1, LS2, LS7 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.

    I have a Dragon slayer Callies crankshaft for a LS1. It has a 3.500 stroke with a 2″ pin size. Would you have a connecting rod for this setup? It will be going into a boosted motor but it will be for street use only so boost levels will not be very high (probably only 8-10 lbs).

  2. molnarrods says:

    Hello Charles,

    At this time there are no Molnar Rods LS series engine connecting rods that are made for use with the 2.000 rod pin size. Thank you for checking with us, sorry we could not provide the rods you need at this time.
