GSC P-D Mitsubishi 4B11T Beehive Valve Springs & Ti Retainer Kit (Use w/OE Spring Seats)

The GSC Power-Division Beehive Spring Kit with Titanium Retainers is a high-performance valve spring set designed specifically for the Mitsubishi Evo X equipped with the 4B11T engine. This kit includes 16 titanium retainers and 16 beehive valve springs, engineered to provide superior load retention and durability under high-stress conditions. Constructed with ovate wire and advanced heat treatment processes, these springs deliver excellent fatigue resistance and consistent performance throughout their lifespan. The use of titanium retainers reduces overall weight, contributing to improved valve response and engine efficiency, making them ideal for high-revving applications and performance tuning.

Designed for Mitsubishi Evo X models, the kit is suitable for engines with the 4B11T configuration, typically from 2008 to 2015. These springs are intended as an upgrade for stock components, offering enhanced spring load capacity and longevity for aggressive driving, track use, or high-performance builds. Installation involves replacing the stock valve springs and retainers with these direct-fit components, ensuring compatibility and reliable operation. The kit provides all necessary retainers and springs for a complete upgrade, supporting increased valve control and engine stability during high RPM operation.
