Eagle’s new Extreme Duty connecting rods are forged in our unique twopiece forging using our proprietary nickel/chromium steel that exceedes ASME E-4340 steel standards for tensile strength and yield strength. Extreme Duty rods feature extensive surface finishing engineered to remove surface imperfections to further enhance fatigue strength. 3/8” ARP Custom Age 625+ bolts hold everything together for the ultimate in extreme power handling and durability. Eagle Extreme Duty connecting rods are the ultimate connecting rod for your extreme powerplant.


270,000 psi tensile strength,
3/8” ARP Custom Age 625+ bolts
Additional stress relieving
and surface finishing removes
imperfections resulting in
improved fatigue life.

ESP ARMOR
ESP Armor is a revolutionary new surface finishing process that is available only through Eagle. Similar processes exist, but ESP armor is unique because it is NOT A COATING, nor is it a chemical etching process. ESP Armor is a unique suface finishing process that results in an incredibly slick surface. This has many benefits. First and foremost is reduce bearing friction. By giving the oil a slicker surface to slide along, the bearing friction is reduced. This will also be evident in slower oil heating, reduced windage losses, and improved corrosion resistance. You will also notice that your bearings will live longer as a result of ESP Armor. The finish is unmistakable. Although it resembles chrome, it is not a coating that might flake off or wear out. Eagle is so confident in the effects ESP Armor has on our rods and cranks that we include a ONE YEAR LIMITED WARRANTY against breakage when ESP Armor is used on any 4340 steel crankshaft or H-beam rod. Many customers have tried it and all have been not only pleased, but surprised by the results. You’ve got to see it, and use it, to believe it!



ESP Armor Dyno Test
Our test engine was a 700 hp big block Chevy (496
CID) drag race engine. The test was performed in
a controlled environment by an independent dyno
tuning facility. Absolutely nothing was changed
in the second session except the crankshaft had
been finished with ESP Armor. The engine gained
30 hp in two seperate rpm points, and gained 19
hp at peak. These results are consistent with our
first test done with a typical street 383 CID Chevy
small block.

CRANKSHAFT OPTIONS












PENDULUM UNDERCUTTING
Most any crankshaft can have the counterweights pendulum undercut. This process reduces weight by removing material in low-stress locations so the effect on strength is minimal. these areas are difficult to reach and require specialized CNC equipment and tooling. Typical weight reductions are from 2-4 pounds depending on the original design of the crankshaft.


PART NO.
Your Cost
NOTES
P100 $273.71 Pendulum undercut counterweights














SECOND KEYWAY FOR BLOWER
Due to the added shearing forces a blower pulley puts on the crankshaft key, a second keyway machined 180 degrees from the original keyway is a popular option. Available on most crankshafts, this is a great way to help reduce key breakages on blower applications.

NOTES
A100 $63.03 for second 3/16” keyway
A110 $63.03 for second 1/4” keyway
















ROUND REAR FLANGE FOR SPRINT CAR
A typical rear flywheel flange cannot be used in a sprint car application due to the unique drive system. Eagle can machine the rear flywheel flange round for use in spint cars. This, of course, should be done before balancing.
