Quality parts!
Better put your big boy pants on when installing these springs! Without the right tools you'll lose an eye! Don't cheap out on a valve spring compressor that will break. Be sure to get the LS style compressor that bolts down through the rocker bolt. These springs have some serious pressure for serious applications!
