Do these valve springs come with retainers and seats?

No, these GSC Power Division Stage 1 Beehive valve springs are designed to utilize your vehicle's factory retainers and spring seats. You will need to reuse your original parts or source compatible replacements separately.

What kind of performance improvement can I expect?

These springs are designed to handle higher RPMs and prevent valve float, which is common with engine modifications. They offer improved valve train stability compared to stock springs, allowing your engine to perform more reliably when pushed.

Are these suitable for a mild build or a more aggressive one?

The Stage 1 designation suggests these are well-suited for mild to moderate performance builds. They offer an upgrade over stock for engines with intake and exhaust modifications, or light turbo upgrades, helping to keep the valve train stable.

Product Details

If you're looking to get more out of your 4G63T engine, especially if you're planning on some performance upgrades, a good set of valve springs is essential. These GSC Power Division Stage 1 Beehive valve springs are specifically made for the 4G63T engine found in models like the Mitsubishi Eclipse, Eagle Talon, and Plymouth Laser. They're designed to handle increased RPMs and the demands of a modified engine, helping to prevent valve float when you're pushing the limits.

What's neat about these is that they're designed to work with your factory retainers and spring seats. This can simplify installation and potentially save you some money on extra parts. The beehive shape helps reduce mass on the valve stem, which can improve valve train stability at higher engine speeds. They offer a solid improvement over stock springs, making them a popular choice for builds that are stepping up from a completely stock setup.

When installing these, remember they are designed to work with the original equipment retainers and seats. Make sure to follow the manufacturer's instructions for proper installation to ensure they perform as expected and last a long time in your engine.
