What is the purpose of dual valve springs?

Dual valve springs create a stronger spring assembly that can better handle the increased lift from performance camshafts. This helps prevent valve float, ensuring more consistent engine performance and protecting against potential damage.

What is the installed height for these springs?

These COMP Cams valve springs are designed to be installed at a height of 1.770 inches. It's important to ensure your valve spring seats and retainers are compatible with this measurement for proper function.

Are these springs suitable for stock GM LS1 engines?

While these springs are well-built and offer improved stability, they are particularly beneficial for LS1 engines that have been modified with high-lift camshafts or are intended for racing applications. For a completely stock engine, they may be more than necessary, but they offer a robust upgrade.
