Mountain13x15mm Double Box Universal Spline Reversible Ratcheting Wrench; 90 Tooth Design, Long, Flexible, Reversible; MTNRM1315

This double box ended wrench is low profile and the ratchets are reversible. I bought this to work between my engine and firewall to remove the EFI harness. It was ideal for the tight space and long enough to reach down to the nuts and lower profile than all of my shallowest sockets. Use caution though, you have the ability to over torque small bolts easily.

I had to install a cam synchronizer sensor on my 2000 Jeep TJ and this wrench was long enough and narrow to turn the crank and stay more clear of the fan blades.

They worked well while replacing water pump, crossover pipe, serpentine belt, pulleys and hard to reach hoses on my Ram Promaster 2500 Cargo van! Can’t tell you about durability yet but they are a must when dealing with No space, 11 to 17 degree weather, snowing and exposed to the elements! Very happy!!!……April 29, 2023 and the 8mm failed! Going to drop down to 3 stars until I receive a replacement!Update: Brand new replacement immediately! Than you American Tool!

As an auto tech I have had these for over a year but only used them a few times when I really need to get deep into a dash panel, around a steering shaft, or down in the middle of an engine compartment, or get to an exhaust nut- ie, the 5.3 Chevy exhaust manifold nut that I have no other tool for because the frame and wire harness is in the way. If you have replaced the cylinder heads on these engines you know the challenge. All the engines I have worked on so far have been fairly new so the nut wasn't completely rusted out but still I was very impressed that it tool off the nut without a problem.As Bob mentioned in another review- the wrenches will stick to the nut or bolt when they are new so they can be a bit difficult to get off the fastener after loosening. I use these wrenches very rarely but for the cost they are completely worth it and a time and knuckle saver for those tight spots where nothing else works. I think they will last a lifetime for me. I imagine they would wear out if used every day but most gear style and flex head wrenches will.

While these are solid wrenches that could definitely withstand a long life in the shop, beware of possible quality control issues in your individual purchase. I'm extremely happy with the robustness and overall machining,(tactile and functional, nice polished finish)Despite all this, the 8mm's black toothed insert was loose in the package. The retaining ring that should've held the mechanism firmly together was nowhere to be found within the sealed plastic enclosure or in the cardboard shipping box, so natural assumption is it was never installed in the factory, and yet somehow made it through their quality control. It's hard to imagine it could be lost anywhere else given the difficulty it would take to remove one that was properly assembled.That said, I imagine the seller would probably handle that, if it happens to you given people's positive experiences.In my personal case, I'm impatient and handy with plenty of junk lying around, so I robbed the clip out of a broken cheapo ratcheting wrench I had lying around, and fixed the issue myself. I simply couldn't wait the time it would entail to go through replacing the incomplete unit.Seriously though, these things mean the business. While I have only just gotten them, and have yet to put them through their paces, they radiate the same sense of quality as the tool truck equivalents I used every day in life back when I was working full time at the shop. If you can catch them on sale, I wouldn't think twice to pull the trigger on a set. I do however hope you have better luck than I did with respect to quality control. I imagine I was just rather unfortunate mishap, and that it doesn't speak to the character of the company who produces them.

It worked. It worked like a charm. I was changing out a serpentine belt on my Honda. The way they have the tensioner, you have no way to get a ratchet set in there to get enough lag to put the new belt on. I tried the belt removal tool and tried flat ratcheting wrench but did not work. Regular wrench doesn't have enough angle to really get a good pull on the tensioner with out it popping off the bolt.But this one, this one has a sort of an extention to the wrench where it goes on just right on the tensioner bolt and you can remove and replace belt with ease. I spent half a day trying to use the inadequte tools to put on the serpentine belt. Ordered and bought 2 other type of tools and still ended up failing. Then comes along the Mountain wrench.... Ahhhh, it was great.......... Just the right tool for the job.

I like the reverse ratcheting feature. They are very long for the added torque you may need. Nice little box holds them in place.

I've used these swiveling ratchet wrench a few times now, and they do come in handy. I like the length.The racheting mechanism is a little stiff, so once one breaks the nut / bolt free, you might have to help it along. I had to put my other hand on the top part of the bolt to keep the mechanism from just rotating the bolt back and forth. And the little button / switch to make the wrench switch the operation from loosen to tighten wasn't very sure fire. I had to press that switch rather firmly to get the ratchet out of the free wheeling mode that it ended up in when I first tried to change it from loosen to tighten. I have these soaking in a light oil now to see if that helps. I'm starting with 4 stars here and we'll see how these work out. Not bad for the money at this point.

I ve been a car tech for 25 years and those are what u need for those hard to reach places..,the design is perfect and they feel really strong ...great product...highly recommend.

It is amazing. Really nice and very convenient. I should have used earlier. Especially, it is very useful to take the belt off.

Awesome tools . The length make it so easy to leverage rusty bolts . They fitting in ties spots. I highly recommend

A must-have wrench set for mechanic. Those wrenches are perfect for tight spot such as tensioner or adjust rear toes or cambers. Love it

The tools are great. My issue is with that the box, and subsequently the wrench holder, arrived damaged and cracked. Poor shipping caused my brand new wrench set to look aged and I was left with A bit of a sour taste in my mouth
