COR FAB GM LS Valve Spring Compressor Tool Made in USA

I changed the valve stem seals on my 2007 Avalanche. I used this tool to remove the valve springs on my LC9 5.3 L engine. Worked perfectly in coordination with a pneumatic valve holder running at 100 psi. No warping of the tool observed. Good tool for the price, but I would recommend the version that compresses 2 springs at once if you were going to be performing this job regularly.

Used this tool for my 5.3 cam install. Use 3n1 oil on threads every other valve. Took me long because I kept dropping keepers in my gravel driveway. Also helps to use a pass thru socket rather than a open end wrench to tighten and loosen.Tool got the job done.

Works as it is designed to. Handy tool. Just removed all 16 springs(two heads) and it only took about 30 minutes.Helps to lightly tap the retainer with a hammer to loosen the keepers before tightening down.

Very easy to use and very sturdy. Used this tool a million times and never had an issue.

Giant POS bent trying to install the first spring. Crude and unfinished. Weak "fabrication" I used that term loosely. Avoid at all cost. Get good proper set of valve spring compressors dont even attempt to use this.

Easily gets the spring keepers off. This tool wont compress the new pac 1218 springs far enough to put the keepers back on it just bends. I knew I should have bought a better tool.

It worked okay...did the job removing the keepers but it started to bend at the end of the job. Thicker would be better.

I got my BT dual valve springs off in no time with this tool on a set of LS3 heads.
