What rear ends on '37
 
I've spent countless hours researching how to build a '37 Chevrolet.

I'd like to get as many opinions as I can about what rear ends fit under a '37 Chevrolet 4 door sedan the best. If possible, I would like to stick with a Chevrolet rear end, but if it truly be worth it I wouldn't mind going with a Ford.

Could others please share their experience and knowledge so I can begin trying to find a rear end.

Thanks,
Brandon

I will be using an 8.8 out of a ford explorer

How close are the measurements from the explorer rear end to the original? If I want to use 8 inch wheels, will the original width get me pretty close to where I need the tires to be in the fender. (I'm just looking for them to look normal and not stick out too far or stick in too far).

Thanks,
Brandon

the 8.8 explorer (drum brake) is about 1.5" wider than stock (I think thats what I remember)

the biggest problem with the explorer rear, is an off-set pinion
super tough and easy to find, and find parts for
but it does have the 5 on 4.5 ford bolt pattern
however you can just make your front end ford also :thumbup:

unless you (or your wife) have your heart set on a specific chevy wheel

I will measure both rears and make sure on the width :thumbup:

Thanks, I appreciate that.

Well, we're pretty set on reproduction wheels, which I'll probably have to buy from Coker, that look just like the original wheels but have an updated bolt pattern and can be obtained in an 8 inch rim. I may be wrong on this, but I *THINK* that Coker may offer a wheel with both bolt patters on the same wheel, so if they do, that would be a great way to go. My only regret is how expensive they are.

I'm thinking a rear end ratio in the 2.7x or 2.9x would give me the best gas mileage without straining the car around town and killing the city mileage. What are your opinions on this?

Thanks,
Brandon

I just measured both rears (by myself)
stock 37 was about 59" -@ wheel mounting surfaces
and the explorer 8.8 was about 59" 1/2" @ wheel mounting surfaces
(I was wrong in the previous post about the difference, its only about a 1/2")
so they are very close in width :thumbup:

they come in a 3.08 ratio, but if you are using an overdrive trans, I would go with a little lower gears
maybe 3.27, 3.55, or even 3.73

here is a good link to a site with some info on the 8.8 rears there is also some good info here if you use the search

maybe someone else can chime in, about some other choices on a rearend and/or gearing choices

Vetteman61 01-14-2012 03:37 PM

Ok, thanks for the info! According to the site, if I wanted rear disc brakes, which I believe I would, I would need to find a 95-01 Explorer (or Mountaineer).

anyone else have a suggestion for a rear end or ratio?

stock width is about 59" @ wheel mounting surface

Vetteman61 01-17-2012 03:45 PM

I have read all the links from all the posts. I have called numerous junkyards and ALL of their books say that there was not a 3.08 installed in the 95-01 Explorers, and to get a 3.08 I would have to go pre-95.

Maybe I have my brainhairs crossed, but I thought the websites I'd read, which were quite lengthy, said there was a 3.08 offered and the code for it was 43, which was an open diff 3.08.

Can anyone clear this up?

Thanks,
Brandon

If you want the Chev rear try the rear from an S-10 4x4 as they are a bit stronger and have the chev bolt pattern. Wheels Speedway may have them or do some shopping..vintique wheel is another source that I am aware of..
