About this part

Product Details

Manley Performance is well-known for making strong engine components for serious builds. If you're working on a Nissan GT-R with the 3.8L VR38DETT engine, these Pro Series Tri Beam connecting rods are a serious upgrade. They are designed to handle the demands of high-horsepower applications, especially those involving turbocharging.

These rods are crafted from 300M alloy steel, a material chosen for its exceptional strength and durability under extreme stress. The "L/W" in the name stands for Lightweight, meaning these are designed to reduce rotating mass in your engine, which can help with quicker engine response and higher RPM potential. The Tri Beam design is a specific Manley feature that offers a strong yet relatively light profile, balancing rigidity with weight savings. This set is built to be a direct replacement for your stock rods, but with a significant increase in capability for boosted or modified engines.

When you're building an engine like the VR38DETT, the connecting rods are a critical link. Choosing a well-built set like these from Manley means you're investing in reliability for your high-performance build. Make sure you have the proper supporting components, like balanced crankshaft and pistons, to get the most out of these rods.
