If you’re looking for an easier way to swap out valvesprings in your LS powerplant, then this is a tool you need to check out. The trick design allows you to get into tight spaces, enabling you to remove one or two valvesprings at a time—even within the confines of an engine bay. Of course, you can also use it with the cylinder heads mounted or with the cylinders heads off the engine block.
This gem is good for all ’97 to ’11 Gen III/IV LS-based engines.
