Different Applications Require Different Connecting Rod Designs

Every application is different, which is one of the reasons we have so many different piston rod choices available. It is important to choose the right rod when considering the many forces created by factors such as engine displacement, crank stroke, con rod length, piston speed, compression, horsepower, boost, nitrous, and the type of racing you are involved in. All of these factors are important to consider when choosing a rod.

In addition to standard weight class rods, we have extra heavy duty models for extreme boost and nitrous applications, as well as extra lightweight models for use in limited or restricted racing classes. If you need assistance, please do not hesitate to contact us and we will be happy to help.

Molnar Power Adder Rods

example of a new design for specific applications is the Molnar power adder rods series. As more and more performance enthusiast and racers use turbochargers, superchargers and nitrous with their engines the demands for heavier duty rods for those applications has become greater. The PWR ADR™ rods feature additional strength to handle these higher output engines without adding additional mass in areas that do not contribute to a stronger more durable rod.

Molnar Power Adder Plus Rods

You asked for it and Molnar Technologies responded by delivering a line of extreme duty connecting rods. The number of people building extremely high output engines these days using very high boost superchargers, large displacement very high boost twin turbo set ups and very large NOS shots created the need for even stronger rods for certain applications.

Stroker Engines

When installing a stroker crank there are sometimes clearance issues due to the longer moving the rods closer to the oil pan rail and the bottom of the cylinders and also the camshaft in some engine blocks. To improve clearance many Molnar stroker cranks use smaller diameter con rod journals. This makes the external dimensions on the rods smaller which increases clearance and makes fitting stroker cranks into engine blocks far easier.

Small Journal Rod Sets

One of the more recent trends in racing cranks and rods is the use of smaller crankshaft rod journal diameters. Modern materials and designs allow the use of decreased rod pin diameters while still maintaining strength. In addition to decreasing rotating assembly weight this also reduces bearing surface speed, friction and windage losses all of which provided increases in torque and horsepower. In our product listing you will find several piston rod sets that are made to work with small journal diameters.

This wealth of experience is an important factor in designing con rods which provide lightweight while delivering proven reliability at higher rpms by removing weight from non-critical areas but retaining material in areas that are the most important for strength and durability for the application.

4340 Steel Billet Molnar Connecting Rods

Molnar Technologies steel H-beam connecting rods are manufactured from 4340 billet steel material and heat treated to provide increased tensile strength. The con rods are then shot peened to further improve durability and increase fatigue life. Except for a few specialty press fit rods, Molnar Technologies rods all include high quality bronze bushings, precision machined, for use with floating wrist pin type pistons. With Molnar rod sets there is no extra charge to step up to ARP2000 hardware which provide superior clamping force, as they come standard in every piston rod set along with lube and installation instructions.

All Molnar piston 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. Close examination of these rods will make evident the pride in workmanship and the obsessive attention to detail that are common in all Molnar performance parts.
