Author Topic: What is better? 4.7's or dual cases (Read 2681 times)

Ok heres how i see it. Marlin has 4.7's for $429.00, Advanced adapters has 5.0' for $395.00. Now what are the down sides to running these instead of dual cases. Are they weeker or just a better route to go? My worries about dual cases is finding a cases cause they are hard to come by for a fair price. I know it would be nice to have that extra lenth in front driveline but am keepin it lower for better stability. Any help would be greatly aprreciated.

you would have alot more options with duels or even duels and a 4.7 gear set personaly i wouldent buy advanced stuff unless i had to id rather go with marlin but thats just me $Beer Chug\'n$

Well is there a difference? I think they both have same products just different names on them. Not only that but there prices are much different. If they are stronger i would like to know cause then i would spend the extra cash.

I say go duals...

If you do go the 4.7's or 5's, read this http://board.marlincrawler.com/index.php?topic=4310.0 why marlins are so much better. I read this thread and the $30 more is a better rout to go.

Correct me if I am wrong someone but, I believe the dual cases is a tad lower in ratio than the single 4.7 so it isn't a totally equal comparison in respect to gear ratio. I have the 4.7 single box and one of the things is that when reversing the gear ratio is still low, I have no choice other than to shift to 4hi to speed up my reverse. This becomes kind of irritating after a while when there's a lot of other trucks you are trail riding with and there are tight spots that require reversing. Other than that, Marlin's stuff works awesome! My

How far you driving that you have to be Mr. Speedy Turtle in reverse...besides, even with dual cases you will still have to shift out of low on one case to change the reverse ratio.
Hehehe, 50 MPH k-turn. Patience is a virtue, no

A lot of trail riding done approximately 1 - 3 miles. I find that with this box, I can use 3rd gear low to simulate 1st gear 4low with a stock box. It's just that when I have to reverse and if I need to speed it up some I shift to 4hi. It all boils down to having more options available with 2 cases. If I had 2 cases, I would trail ride in 4low 2.28 (stock gear ratio with one case in 1:1 and the second case in low) and reverse at normal speed. Again, not a biggie but, is a consideration.

Yup, that's the only problem with a single case, Once you're in low range you are stuck in super low.

Dual cases give you the option of using the same stock gear ratio that you are now and then shifting the Crawler into low when you need to be super low (doubled down).

A Dual case setup is 2.28x2.28 = 5.2:1 which is lower then just a single case with aftermarket gears.

About the A/A 5.0 gears I would HIGHLY recommend reading what I have here:

I meant speedy turtle in reverse...I suppose I have just never been in a situation that required backing up at more than 1-2 miles an hour. I know in tight situations I take it slow, and the guys I wheel with do too. Anybody screaming with impatience behind you oughta suck it up and realize that wheelin is fun and relaxing...this ain't no race.

BigMike, this is a

observation, but I want to hold you to the same standard as you do Advanced Adapters. In your comparison you note that the AA case is really 4.97:1 rather than the 5.0:1 that they advertise. 2.28x2.28 = 5.198:1...ok I will accept 5.2:1 as technically correct, I failed to notice the third decimal.

There is no question that the Marlin gears, case or any other product are superior to the competition. I have a single 4.70:1 case and it can be a pain to back up in low range, but it has never been a problem on the trail. It almost takes as long to shift it twice as it does to just backup.

What are you, or did you, take in school? You knowledge is amazing and I'm curious about your background.

the third decimal.

I did the same rounding with A/A..
(37/20) x (43/16) = 4.971875:1 = 4.972:1 = 4.97:1 (rounds down)
I've always told people that two cases are a 5.19 but I've tried to stop that since it rounds up to 5.2

I've just had one to many road trips sitting next to Marlin

And to be perfectly honest, I'm only good with what I know, which happens to fit this world perfectly (Toyotas)
Put me somewhere else and I'll be par at best

As for school Im getting my butt kicked by Mechanical Engineering. Finally gonna transfer to State this Fall

You do Essays in English, and then word problems in math. Then you will learn about Calculus and then go into deep study about ordinary differential equations. Now I am learning how to mix ODE's with Matrices, and now we are getting into Word problems using a high order ODE Matrix. Then I hear I will have to start doing Essays again about why 1+1 = 2.

I thought it equaled 3 ?

My math teacher in High school got pissed when I told her I wasnt doing imaginnary numbers. I turned in a blank sheet of hwk, and he said you didnt do your hwk, I said yes I did, we're doing imaginary numbers right? I spent a lot of time outside her door that semester

BigMike - I got the feeling that you were of the engineering mind from what I have read in your posts. The transfer case comparison was the most obvious followed by your AMSoil Denny's conversation. I'm sure that you aren't the expert at everything, but who needs to be great at more than a few things. I'm dumb as a post on many topics...auto mechanics to name one, but I'm learning. Does your dad have any engineering background? The things he figures out and designs are simply amazing (fwd t-case for example), how much are you involved in those projects? Your senior design project should be a snap.

I started doing the mechanical engineering thing and it

so I switched to civil engineering and did well. Linear Network Analysis and Feedback & Controls ran me out. Year 3 of 5 was the hardest for me, I hit the books at least 6 hours a day plus classes, but it was worth it in the end.

Marlin is a hard working self taught prodigy child. His older brother is hobby-less and lives by himself and his younger brother is an excellent electrician but also lived alone for most of his life. In HS Marlin had 3 different paper routes and repaired his teachers cars as he paid his own way through private school. His parents were very poor and Marlin had to do everything he wanted to by himself. But because of his hard work, he got a full 2-year scholarship to a Private college because his HS teachers wrote a letter to the college and told them how hard of a worker Marlin was and that he could never afford to go to college. He graduated with a AS in Industrial Tech I believe and then got hired as a Machinist where he worked for I think 6 years. And then in 1986? he started doing Mechanic work out of his garage and 1 year later opened up Marlin's Automotive.
He was into sand rails and buggys and hit the dunes all the time. He was a avid backpacker/hiker and he can get lost in the forest and survive of the nature without any problems. He has amazing confidence when it comes to the mountains and hiking. He will just head straight off the trail and we wont see him until night fall where he will already be at camp with a fire going .. the whole way without even using the actual trail.

Then he got out of dune buggies and bought a 1980 Toyota truck back in 1984. He is the 2nd owner. He wheeled it for a while and then around 1994 he found out how to build a Crawler and the rest is history.

He's the smartest guy I know.
