K20A Connecting Rods Lightweight and Turbo K20A Rods

Molnar Technologies

Molnar Technologies H Beam K20A 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 Honda K20A connecting rods are fitted with highly durable premium bronze bushings for use with floating pin type pistons. Each rod set for the K20A engines includes ARP fasteners, lubricant and installation guidelines.

All Molnar Honda K20A connecting 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. These rods are an excellent upgrade component for high performance and racing K20A engines.

We have two different rod sets for use in the K20a engine. The lightweight set is intended for use in normally aspirated engines with no power adders. The Turbo set is for use in turbocharged, supercharged or nitrous boosted engines. If you have any questions about which set is the best choice for your engine project please do not hesitate to contact us for assistance.
