Molnar Technologies H Beam Rotax 1630 ACE connecting 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 which also increases fatigue life. All Molnar Rotax 1630 engine rods are fitted with highly durable premium bronze bushings for use with floating pin type pistons. Each rod set for the Seadoo Rotax 1630 engine includes ARP fasteners, lubricant and installation guidelines.
All Molnar 1630 Rotax ACE conrods 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 stock rebuild, high performance and racing Rotax 1630 ACE engines. These engines are currently used in the Sea Doo 300 with other marine and snowmobile applications likely to be introduced.
