Are you looking to squeeze more power and reliability out of your GM 3100 or 3400 V6 engine? One of the simplest and most rewarding modifications you can make is upgrading your valve springs to LS-style springs. At WBodyTech, we’ve detailed exactly what you’ll need, how to do it, and why this upgrade is a game-changer for your build.

Why Upgrade to LS Valve Springs?

Factory springs in GM 3×00 engines often struggle with valve float at higher RPMs, especially when paired with performance cams. Upgrading to LS valve springs provides the stronger seat and open pressures needed to maintain precise valve control, ensuring peak performance, improved reliability, and increased RPM capabilities.

Your LS Spring Options:

• GM LS6 Springs: Perfect for daily-driven builds seeking mild performance enhancements without sacrificing reliability.

• PAC 1218 Springs: Ideal for serious enthusiasts and performance-oriented builds, capable of handling aggressive cam profiles and high RPM operation.

Choosing the Right Supporting Mods:

We’ve laid out all essential supporting modifications—ranging from retainers and valve locks to timing chains and rocker arms. Ensuring compatibility and proper geometry is critical, and we cover it all in detail, from mild to wild setups.

Installation Simplified:

Our guide over on the forums breaks down the installation into straightforward, detailed steps. From measuring installed heights to checking coil bind clearance, you’ll know exactly how to set your valve train up for success.

Pushrod Considerations:

Whether you’re planning a mild upgrade or a high-performance build, we explain when stock pushrods suffice and when custom-length pushrods become necessary, ensuring your valve train operates flawlessly.

Explore Different Setups:

Whether your goals are daily driving with occasional spirited runs or a dedicated high-performance build, we’ve summarized the best configurations tailored to your needs. Find out exactly which setup aligns best with your build goals.
