BoostLine Mitsubishi Evo X 4B11T 143.7mm - Connecting Rod Kit

Forged from 4340 steel, these BoostLine connecting rods are built to handle the increased stress of a performance-tuned Mitsubishi Evo X with the 4B11T engine. At 143.7mm in length, they are a direct replacement for the stock rods, but with a significant upgrade in strength and durability. This is crucial for engines that see higher boost levels or are used in demanding track conditions, where factory components can become a weak point.

The 4340 steel construction offers improved tensile strength and fatigue resistance compared to standard materials. This means these rods are less likely to bend or fail under extreme cylinder pressures. BoostLine also uses a robust I-beam design, which is a popular choice for performance applications because it balances strength with weight. The kit includes the connecting rods and the necessary connecting rod bolts, which are also upgraded for this application. When you're pushing your Evo X's engine hard, having well-built internal components like these rods is essential for reliability and performance.

For installation, it's important to ensure your crankshaft journals are within factory specifications and properly prepped. These rods are designed to fit right into the 4B11T engine, but proper balancing of the rotating assembly is always recommended for high-performance builds. This kit is a solid foundation for anyone looking to build a more powerful and reliable engine for their Evo X.
