Connecting Rods

One of the last components to design in your new engine, the Connecting Rod transfers the power of the pistons to the Crankshaft. 

 

There’s 3 basic types of Connecting Rods, listed in order of increasing cost

 

· Stock —> Whether it’s from your tractor or a whole other model, if we can find a connecting rod that meets the needs of the engine, this is an economical way to put the pistons where they need to be. 

· Welded —> If you’re new to this tractor pulling stuff, this is going to sound crazy…  Imagine this…  We’ve designed a killer motor for you and we need a connecting rod between 14.0” and 14.5” long with a 1.25” pin and 3” Crankpin.  No such critter exists in nature.  Now what do you do?  Simple, using carefully designed fixtures, we take 2 rods, cut each one in half, put them in the fixture and TIG weld them together.  On bigger motors, for added strength, a steel plate is added to the side of the rod to “box” It in.  This results in a strong, economical connecting rod.

· Billet —> For the ultimate connecting rod, you can’t beat Billet.  Although this is the highest cost option, there is no limitations.  You don’t need to find rods, there’s no welding involved, they are just made from solid high strength steel.  Computer Designed and CNC machined.
