Picked up a few Ko-ken things from drpd on the Memorial Day sale. Just got around to opening the box.
Finally got one of their ratchets with the quick release button (3725ZB). I like it, the button sticks out quite a bit, unlike Nepros ratchets where the button is flush. Much easier to depress the button. Might not be ideal if you’re working in a tight area where there is a chance of something hitting that button. For that scenario, I have other ratchets. My old 36 tooth 3/8 ratchet will get relegated to my car tool kit.
Finally got some 3/8 SAE Ko-ken sockets. Now all my old Craftsman tools can go to the basement.
Now onto the “quick spinner” 4711XZ. This is my first disappointment in a Ko-ken tool. Where to begin:
1) The grip portion has some play in it. It wobbles a bit. This is supposedly better than the non-Z version, so that one must have been really bad.
2) Looking at listings on ebay, it is advertised with a Ko-ken-branded cloth case/roll for it. Mine did not come with one, just the typical Ko-ken plastic zip-lock packaging. I thought about returning it because of no case, but DRPD did not advertise it with one, and I didn’t want to go through the hassle.
3) The lever bar is too short for removing lug nuts, plain and simple. I tried it on both my BRZ (M12x1.25 studs) and my 4Runner (M14 studs I think…). I torque both to 90 ft-lbs when I change wheels. BRZ came loose with a moderately high effort (“this *****, I wouldn’t use this”). 4Runner lugs required way too much effort (“f-this, never again”).
4) The handle you yank on has no grip section, and since it is oval, your hand is actually on the narrow side, if that makes sense. So it’s worse than no grip, it’s actually like yanking on a smaller diameter bar. I tried my 3/8 z-series breaker bar that has a handle and is about 2” longer, and it was a much better experience.
5) It’s quite expensive, which is why I held off on it so long. You can find it for about $100 on ebay, DRPD was more expensive, around $120 on sale. I recently had a bad experience buying something from Amazon Japan, and was willing to pay the $20 for an American seller and it got me free shipping on the other stuff.
I suspect if this “quick spinner” is not meant for our market, at least not for
removing lug nuts. This might be suitable for a kei-car with smaller wheel studs. But I would not want to rely on this for changing a wheel on the side of the road at night in the rain or snow. An 18” breaker bar is far cheaper, more versatile, more comfortable to use, and mechanically simpler.
Where this quick spinner could be useful would be threading
on lug nuts prior to torquing. But with how cheap cordless impact wrenches have become, everyone who regularly changes wheels at home should have one. I would not recommend this 4711XZ to anyone, other than a collector.
