COMP Cams 4914 Crankshaft Socket for GM Gen III/IV LS-Type Engines

Hopefully my review clears up all the wrong and confusing ones. You will revive the tool pictured on the right, the other on the left is a SBC sprocket and not correct. I’m sure revisions have been made to this tool over time to address some tolerance or application issues. I’m building an LS7 stroker and this socket is perfect! Machined very well with approx .003-.004 tolerance for a nice slip fit over oil pump gear and crank snout. My crank sprocket is longer 2009+ one piece cam sprocket style for a katech dry sump pump. You can see in the photos the key way is very long once slipped onto the socket and will work on LS3/LS7 no problem. On an LS7 dry sump this tool slides over the long crank snout and onto the oil pump gear by 3/8- 7/16 which is enough engagement to get the set screw to snug it up and start turning the crankshaft to degree the cam. Very happy with this tool and now on to purchasing the degree wheel of choice.

Sturdy, nice quality and works perfectly

This tool is great for the purpose it was made for. It was totally worth my hard earned dollars.

Fits over the oil pump drive gear as it should. There’s actually 2 different sockets in the picture. 4914 is the correct socket

Nice tool if it fit. The key way on the tool doesn’t reach far enough down crank to engage the key on crank.

works great on ls3 engines with crankshafts with long woodruff keys. some stores online have the wrong pictures with no woodruff key slot make sure the part number is the same as this if you find this some where else cheaper

Did not fit my LS2. The socket cogs would not fit over the oil pump timing sprocket cogs, not even close.

Haven't used it yet - but appears to be a well made unit.
