ARC 6256 Billet Connecting Rod (+.020)
The ARC 6256 billet connecting rod is a high-performance upgrade for Harbor Freight Predator 212cc engines, designed to replace the factory rod with a stronger, more reliable solution for demanding applications.
With a 3.328" center-to-center length (+.020" over stock), this rod improves piston positioning by reducing how far the piston sits below deck, helping increase efficiency and performance when used with stock crankshafts and standard dished or flat-top pistons.
CNC machined from 7075-T651 aircraft-grade aluminum, this rod provides an excellent strength-to-weight ratio, making it ideal for high RPM racing and performance builds.
ARC’s forced oiling dipper system improves lubrication to the crank journal, helping reduce wear and increase reliability under load.
