Valve Spring Installation Tool,Professional Valve Spring Compressor Tool For LS2 LS1 Valve Spring Installation (Red)

Worked perfectly and took about 25 minutes to do all the springs on a head. DON'T waste your time buying the compressor to do 2 springs at once, they bind up and waste your time. This is quick press on and off using a 3/8 ratchet or breaker bar.I am sure after a few hundred springs with the tool, the aluminum would wear enough to be an issue, but for the price, that is a dumb thing to complain about.If you struggle putting the keepers back on, use a small magnet to pull them and place them, which is way easier anyways.

By far the easiest to use. It even works on the Gen V LTx heads. Unfortunately for the LS3 style intake valves, Texas speed is the only one to offer this style in a kit for both valves. But his is perfect for cathedral ports and Gev V. It's much faster than the $5,000 one I use at the machine shop.

Handy little tool!

Will not work for Chevy small block heads without heavy modification. And still at this point I'm assuming it will work. I still need to go buy a very skinny threaded nut. So if you're building a Chevy small block don't waste your time

Professional mechanic and I thought it worked great. I can see that i am going to wear the tips off due to it being aluminum. I used an old rocker arm bolt instead of the supplied ones but that was personal preference

Great little tool. Easy to use. Just a bit of advise, use the bolt from the lifter it will make it work a lot better!

great product for ls valve springs the perfect tool for gen 5 valve springs just a little difficult on ls3 heads you have to leave it loose a little bit so you can compress spring all the way but great price great product can’t go wrong with it@reclusiveperformance

the gap in between is terrible no room to insert keepers, the tool is sloppy it self does not work smoothly
