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 surface finish 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, reduce windage loss, 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 off. Eagle is so confident in the effects ESP Armor has on there rod and cranks that they have included a 1 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 go to see it to believe it.

Independent dyno testing has proven the ESP Armor finish to gain as much as 30 horsepower over a non ESP Armor crankshaft.
