4th GENERATION H-BEAM RODS
The long-awaited next generation Eagle H-Beam rods is here! Our third design has been used for over 20 years with tremendous success. Our third design has been tweaked and improved slightly over the course of it' life, but has never undergone a serious redesign until now. Our fourth generation ("4D" for 4th Design) features several design improvements around the big end bore to improve big end bore rigidity to help maintain a perfect shape in high rpm and high power applications. Also included is a thicker beam and webbing to handle even more power and load than before. The pin end is also strengthened. Eagle 4D rods are also 100% CNC machined eliminating any change for human error in manufacturing. Racers are making more power than ever with increased use of turbocharging and alcohol fuels. Eagle has risen to the challenge to meet those demands with our 4th Generation connecting rod design. Our new 4D rods will be sold along side our current production 3D rods in many applications.
