HOT RODS Connecting Rod 8140

When you're pushing your engine to its limits, a stock connecting rod becomes a liability. The HOT RODS 8140 Connecting Rod is engineered to handle the extreme pressures and RPM loads that separate reliable performance builds from catastrophic failures. Built with precision metallurgy and meticulous manufacturing, this heavy-duty rod delivers the strength and longevity required for serious racing and high-output applications.

Every detail on the 8140 is designed to perform under stress. The caged needle roller bearing design minimizes friction at high RPM, while the strategically scalloped big end reduces bearing race distortion—a critical advantage when operating near the limits. Double drilling in the small end ensures your wrist pin bearing stays properly lubricated and cool, even under sustained high-load conditions. Shot peening eliminates surface stress concentrations that lead to premature failure, and double honing produces the bearing surface geometry your engine demands.
