Hot Rods 1937 Chevy Pickup Rear end compatiblity

1937 Chevy Pickup

My rear end froze up and I am looking at getting a different one. I was reading online and saw that a Ford 9" rear would work. I would like this truck to stay all GM part (no offense). A rear end that has a low ratio, will allow me go drive on the freeway without the loud gear noise.

Does anyone know what would be compatible for my 1937 Chevy Pickup?

Thank you,

What rear end is in the truck now?

 

4x4 s-10

 

Freeway without gear noise? I think you mean without high engine rpms...


Is this still the original torque tube rearend?

If so, and you are wanting to switch to an open rearend, then you have alot more to do then you think. You'll need to change the transmission too, which means an adapter plate to put an open drive style trans on the original bellhousing, or swapping out the bellhousing for a '48-57 truck one if you want to keep the foot starter. If your stock bell has the pedals attached to it, then keeping it and going with the adapter plate is your best option.
Then there's the wheel bolt pattern. Stock is 6 lug. Did you want to stay with 6, or change to 5?

You will not need a 9" Ford behind a stovebolt six....

 

I would take the rearend apart and determine what parts I needed and go to VCCA old chivvy club forums, google, http://www.hemmings.com/, http://www.oldparts.com/, etc., etc. and buy the parts I needed.

 

Mine has a '57 chevy car diffy out of a powerglide car (3.36 gears, 5 lug bolt pattern).

 

Is that a 5 or 6 lug rear end in your truck? Original Torque tube?
I did a bolt in swap on my 56 GMC for an 85 GMC rear.

It was a Stock Rear end, I have an LT1 Motor with a Turbo 350 Transmission. And I am choosing the 6 bolt pattern.

Thank you everyone that responed.

 

Wife's family has a 37 Chevy PU that was rodded in the 70's and has a complete 56 Chevy driveline. Inline 6, P-Glide and rear-end. It has a flat-bed though, so I'm not sure if the rear-end would fit under a factory bed and fenders. Just curious, why are you sticking with 6-lugs?

 

Not possitive on the width, but I would look at a full size Blazer from the 70's for 6 lug. Maybe a Bronco, if they were 6 lug?

Better off going with 5 lug and updating the frontend as well. Those stock brakes aren't going to be good enough if you want to get on it at all... same goes for the stock master cylinder.

 

When I changed over to disk brakes on my 56 GMC it made a BIG difference
I used the parts from CPP
