For example- rods that need
to accept needle bearings, such as outboard engines, fit this need. The
roller action of the bearings reduces the drag on the crank,
therefore increasing overhall horsepower and
Recently we have
developed fractured rods for small block Chevy engines. "The results are
amazing," commented Greg Cunningham, "the engines are outlasting those with
standard style rods; and fractured rods let the engines rev smoother and

We are the premier
manufacturer for tractor rods. All of our rods are made with a wider web at the
beam for longer life and durability. The H-I design is made from 4340 billet
steel, which is stronger than the stock tractor rods.
We have designed the perfect
rod for John Deere owners. Our special billet rods eliminate welding of two
rods! Each rod uses our cross grain
manufacturing process. All of the rods we make come complete with full floating
bronze bushings and our own rod bolts. The bolts are rated at 296,000
OUTBOARD ENGINE RODS
We make these unique rods.
Each rod is:
- Made from one-piece
- Fully CNC machined
- The cap is fractured off,
and the cap is then bolted into position, similar to a puzzle piece that fits
only one way!
- Both the big end and pin
end are heat treated to 60 rockwell to accommodate the needle bearings
designed a special, precision MPR (Marine Power Racing) rod because of
the high demand that is placed on the internal engine parts from outboard
The MPRs are fully CNC
machined and made from one-piece billet material. To make the rods superior
required a precise process called FRACTURED. After the rod has been machined,
the rod cap portion needs to be fractured off. Then the cap is bolted back into
position. It is similar to a puzzle piece that can fit only one way.
The big end and pin of the
rod undergo a heat treatment to 60 rockwell, which accommodates the needle
The MPR rods have been race
proven to outlast conventional rods. MPRs are ideal for Formula I and Drag
