Different applications require different connecting rod designs

Every application is different, which is one of the reasons we have so many different rod options available. It’s important to choose the right rod when considering the many forces created by factors such as engine displacement, crank stroke, connecting rod length, piston speed, compression, power, booster, nitrous and the type of racing you do. These factors are important to consider when choosing a rod.

In addition to the standard rods for the weight category, we have extra heavy models for extreme boost and nitro’s applications, as well as extra light models for use in restricted or restricted racing classes. If you need help, don’t hesitate to contact us and we will be happy to help.

Molnar Power Adder bars


an example of a new design for specific applications is the Molnar range of counting rods. As more and more performance enthusiasts and racers use turbos, superchargers and nitro’s in their engines, the demands for heavier rods for these applications have grown. PWR ADR™ rods feature the added strength to handle these higher horsepower engines without adding extra mass in areas that don’t contribute to a stronger, more durable rod.

Molnar Power Adder Plus Rods

You asked for it and Molnar Technologies answered by delivering a range of extreme duty connecting rods. The number of people today building extremely high-performance engines using very high-performance superchargers, large displacements with very high charge with twin turbos, and very large NOS strokes has created the need for even stronger rods for certain applications.

Stroker engines

When installing a lifter crank, there are sometimes clearance problems due to the longer movement of the rods closer to the oil pan rail and cylinder bottoms, as well as the camshafts in some engine blocks. To improve clearance, many Molnar cranks use smaller diameter connecting rod pins. This reduces the outer dimensions on the rods, which increases the clearance and makes it easier to mount the crank arms to the engine block.

Small Journal Bar Sets

One of the more recent trends in racing cranks and rods is the use of smaller crankshaft journal diameters. Modern materials and construction allow the use of reduced rod pin diameters while maintaining strength. In addition to reducing the weight of the rotating assembly, this also reduces bearing surface velocity, friction and windage loss, all of which ensure increased torque and power. In our product list, you will find several sets of piston rods that are made to work with small pin diameters.
