13" given the OPs question. My most used 3/8 is ~10" long because it fits and does the job. I use the 12-13" ones occasionally, and the 15 and 18" almost never, in comparison. Yes, there will be an application where you'll need the 15-18", but for me that's a 1% thing.
GM wheel bearing hub assembly. I'm under the car with my 11 1/2'' long flex head ratchet with both hands on the handle pulling with every ounce of strength I got to tighten those 3 bolts. My 17 1/2'' long 1/2'' drive version had too big of a head to get in there. The extra long 3/8'' drive flex head ratchet is on my list of tools to get. I don't know if I need the locking flex though.
I dont know if they exist, but someone probably makes a 20" 3/8" drive breaker bar. If it's really a 1% thing that's pretty rare, what if OP paired the 13" locking flex head with a 20" breaker bar. And that 1% scenario at least he isn't stuck, he can use the breaker bar. Maybe just to break and then finish with the 13"
Looks like Snap On makes an 18"

Kind of weird they make a ratchet that's longer than their breaker bar.
I am so stealing your saying!<SNIP>
In the flow chart of life, you gotta start with the shorter ratchet before going for the longer.

Damn you just blew my mind. If I got a job designing cars, I'd come up with a way to have a hole near the belt tensioner. So you could insert a rod in there, and lock that rod to the wrench that's putting tension.The extra long isn't so much about giving you leverage, but reach. These are superb, almost essential in some cases, for holding belt tensioners. Sometimes you can access a tensioner from the "wrong" direction, cable tie the ratchet handle, and remove the belt relatively unobstructed. Sometimes you need these even from the right direction.
On further thought, would a 1/2 drive breaker bar with Koken Zeal sockets have had low enough clearance to work?GM wheel bearing hub assembly.

That would be an excellent idea. Or even just a locking pin.Damn you just blew my mind. If I got a job designing cars, I'd come up with a way to have a hole near the belt tensioner. So you could insert a rod in there, and lock that rod to the wrench that's putting tension.
I only change my belt every 5 or so years, but it's enough of a pain in the **** that I'd love this feature. Actually, come to think of it, I should probably just have a friend pull tension while I do the belt with two hands.![]()
If you could only have one long locking flex 3/8 ratchet would you go with a long one like snapon makes one in 13 inches or would you go extra long like snap on is 20 inches?
Basic car repair work. Youre allowed only one.
That would be an excellent idea. Or even just a locking pin.
Unfortunately, while most of us here are practical people and can see the need for such things, engine designers are not.
If you work on older vehicles, which I generally do, you have to remove the belt before swapping an alternator, water pump, idler pulley, ore even the tensioner itself, so the requirement comes up fairly often.
Perhaps check some of the prices on Japanese websites. The weak Yen is giving some competitive prices at the mo.I've been eyeballing Koken Zeal low profile sockets lately and looking for excuses to buy them in 1/2 drive.
As I was writing that I was thinking the same, but can't remember either. Not something I've worked on recently.I've seen that on a brand of European or Japanese cars, but I can't remember which one![]()

A lot of tensioners have the ability to pin, even some BMWs.As I was writing that I was thinking the same, but can't remember either. Not something I've worked on recently.
Not BMW's I can say for sure...



Did my B8 Audi tensioner about a month ago and it had a pin. I can't recall a single tensioner that hasn't had the ability to pin, which is why I keep a handful of pins in my top drawer!

That might've worked, but I would've had to use a 12-point socket to get the handle out of the way of the floor.On further thought, would a 1/2 drive breaker bar with Koken Zeal sockets have had low enough clearance to work?

Sounds like I need to look at mine more closely.

Except of course, that I can barely see it at all, hence I'm using my extra long ratchet to even reach it...!

That ratchet would be perfect for rotating the engine over by the crank bolt, but it's more of a under-car ratchet.Not many places under the hood you'll have room to swing a 20" handle. If you need that much leverage chances are you should step up drive size.
Interesting! What's changed with modern ratchets to negate the need for breaker bars? Are they just so much stronger that they can handle more torque without breaking?Maybe it’s because, like so many on here have been saying for years, modern ratchet design has made the breaker bar near obsolete.
Yes.Interesting! What's changed with modern ratchets to negate the need for breaker bars? Are they just so much stronger that they can handle more torque without breaking?
I became a convert using flex ratchets after getting a long 3/8 drive flex ratchet. 1/4 and 1/2 drive extra long on order. Reading GJ and ordering with a few clicks of the mouse is dangerous.Damn the more I read the more I see people saying they don’t like locking flex head. So now I’m wondering if I should just go with regular flex
