Cut your valve spring installation time in half with our valve spring tool!  This setup will make any valve spring swap easy!  The LS1/LS2/LS6 tool will only work on cathedral-port cylinder heads, and the LS3 tool will only work on LS3 rectangular-port cylinder heads.

You can also add the 14" compressed air adapter that screws directly into the 14mm spark plug hole to hold your valves up in the cylinder while you change the springs!  This will alleviate the possibility of dropped valves and save time of having to put each piston at TDC before swapping the springs.
