Your cart is empty.When slipped on the end of a crankshaft, these specially designed sockets let you use a 1/2 inch drive ratchet or breaker bar to rotate the engine assembly. Our sockets also have the unique feature of a provision to hold our degree wheels or any wheel with a 1 inch or larger center hole. The knurled retaining nut actually sandwiches the degree wheel and holds it in place. This can then be loosened while on the crank snout so that you can turn the degree wheel independent of the engine, which is really handy when finding TDC.

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

This crankshaft socket will not fit a gen 1V 6.2 engine. Too small of diameter where it fits onto crankshaft.

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

Well have many Comp cams tools. Disappointed with this one. Tool fits on crank ok as it should. Problem is the hole bored for the crank snout. My crank was 1.482" . The id of the tool was 1.535" . Problem there is - it only has one set screw. So the one set screw pulled the tool crooked. The degree wheel did not rotate true anymore. There is .050" of total clearance between the crank snout and tool id once tightened. So i had to dig through the garbage. Find a old kleenex box with .012" paper board. Double it up and stick it inside my tool. So that took up the .025" . Tightened my ONLY set screw. And my degree wheel ran true now. Long story short tool needs to have the correct id or have a 2nd opposing set screw or a filler spacer supplied. Id be more understanding if i bought no name white box from Ch1na. Cmon guys - its a Comp tool. Ls stuff and tools are the biggest seller now.

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.

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

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

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
