Supertech Mitsubishi EVO X 4B11 Beehive Valve Springs Kit

This kit includes a full set of Supertech Beehive Valve Springs and matching retainers specifically for the Mitsubishi Lancer Evolution X with the 4B11 engine. These components are crucial for ensuring your engine's valvetrain operates correctly, especially when you're looking to push the engine's performance limits or rebuild the top end.

Beehive springs are a popular choice for performance builds because their tapered shape allows for lighter retainers compared to traditional dual springs. This reduction in mass at the top of the valvetrain means less inertia, which helps prevent valve float at higher RPMs. The springs themselves are made from well-built materials designed to handle the increased stress and higher engine speeds often found in modified 4B11 engines. This improved valvetrain stability is key to making more power reliably and safely. The kit is designed to be a direct replacement for your stock components, simplifying the installation process for those rebuilding or upgrading their engine.

When installing these, it's important to follow the manufacturer's recommended procedures for valvetrain assembly. Ensuring proper spring seat pressures and retainer installation is critical for the longevity and performance of your engine. This kit is a solid option for anyone serious about optimizing their Evo X's engine for performance driving or track use.
