Works good
So far so good. Had it for about 8 months now. Can handle the high torque when I torque crank bolt and can handle breaking loose a crank bolt manually with beaker bar when weighted 24mm socket isn’t available. I’m a GM tech

Worked perfectly on my L83
I bought this to do a cam swap on my 2017 Tahoe 5.3. I saw mixed reviews about how well it fit, and based on the price, I expected mediocrity. Turns out it engaged the flywheel perfectly on my truck with the engine at TDC, held steady throughout the entire process, no issues whatsoever.

Works, but could be better
The actual function of locking the flexplate works as it should, and the price was fine. The issue that cost this product one star is that the included bolts have a 14mm head. Nothing on a GM vehicle requires a 14mm socket. The starter bolts that have to be removed to install this fixture have 13mm heads; why wouldn't the manufacturer include bolts with the same head size so you can use the tool you already have in your hand while you're under the vehicle? Minus one star for having to crawl out from underneath to fetch a different tool.

Works well for the home mechanic
Mounts right up to starter location on my LS3. Held the flywheel in place well enough for the crank bolt to be buzzed off. Would give it 5 stars but the webpage won't allow me to click the 5th star.

Had to put the flywheel on WITHOUT spacer for the lq4. Just took out the bolt without issue.
