MR HELLO LS Valve Spring Compressor Tool Compatible for Chevy LSX LS1 LS2 LS3 LS6 4.8 5.3 5.7 6.0 6.2 Engine 67605

Works as advertised. Old school tech works, simple, direct, easy to use. functions and is a good value

Super easy to use and works great

I have only done 8 of 16 valve springs so far, but have had ZERO issues. Changing from stock springs to BTR SK018 springs. If used as intended, I don't see how anyone would have any issues with this product. Price point is great, took is easy to use, and so far, it seems to be very durable, as nothing appears to have any wear at all after changing 8 valve springs.

Threads we’re not cut clean to run the large bolt through which made the tool harder to use. Still got the job done

Quality is a little iffy, but I was able to replace an exhaust valve.

I have a Chevy 4.8 and could not for the love of God find a valve spring compressor tool that work I even bought one that was $125 that would not even work for these heads I bought this tool right here and let me tell you if you put it on right it works like a champ the tool is very well made good fast shipping and easy-to-use

Worked perfectly & as advertised. I set this up incorrectly at first. The long bolt used to compress the springs does not sit flush with the clamp, so you’ll have to mess with that a bit but overall I am very satisfied with this purchase.

Well it worked great on one side, then started the other side and the bolt started to bend and the washers started shaving. Very glad they have two bolts and nuts in the box. But just beware of the metal shavings and watch the bolt if it starts to bend replace it with the other one, you don’t want the springs flying off and hitting you! All in all worked great, and great price.

Worked great saved alot of time. Did exactly what it should with no issues

This is a decent tool. I would use some engine oil on the threads to prevent them from wearing out. It will work well for replacing valve springs while the heads are still on.
