R&R Aluminum 5.669 Long Connecting Rods L19 Bolts Lexus Toyota Supra MK4 2JZ-GE 2JZ-GTE 2JZGTE

Aluminum Connecting Rods offer the benefit of absorbing vibration and load that may cause a steel rod to bend or break. While they are sometimes lighter than steel rods, the real benefit comes from the increase in abuse they can handle over a steel rod. 


The downside to an aluminum rod is that the steel rod will live longer, however the aluminum rod will usually live as long as the aluminum piston is attached to, so if the engine has to come apart to replace pistons, you will replace rods at the same time when using an aluminum rod.
