What's typically the axle ratio in 2 ton trucks with 2 speed rear end ?  Have the option of upgrading to Dana 110 4.88 with disc brakes .  Splitter rear end really necessary?  Thx

Tried , but only let's 3mb and pic is 3.85.  Will try tomorrow when back at shop.

Common ratio is 5.83-8.11 Eaton 2 speed axle. 13,500 lb rating.

The first # ratio is stamped on the top of the differential next to the plug. Wire brush it well to see it.

If you haul heavy loads the 2 speed is necessary for sure.unless a Cummins is installed.

Awesome.   I would love to put a 5.9 in it but it's more work than I want to get into.  So I should be ok with 4.88 without loading truck to its capacity.  

Thx .

If it has a stock engine (Six?) I'd leave it as is.

2 speed axles are fun to run.

Found the axle #s 

Yes it is a 6 .

Your last picture shows a "Timken" rear axle differential case dated 1949.

Your truck is as you have posted is a C-1-H...1954 2 ton with a single speed axle.

if there were a "A" letter after the H that would define the truck as a factory installed 2 speed rear axle. IE...C-1-HA

See the 1st  picture of Vin data plate examples

All this does not matter much other than what ratio Timken Double reduction axle ratio you have

I have not seen exactly what axle you have but the ratio is stamped on the top flat sqaure pad as shown in the 2nd picture of a Timken 2 Speed axle.

Great .. my axle is round and different than the one in your picture . 

So apparently the truck didnt have factory two speed rear end then.  I am struggling to exactly understand what I have on the truck . Learning more and more and becoming more work, really trying to figure out a build direction and forgo as many surprises as possible . Appreciate all the info . Here is the vin plate

Here is a shot of a typical Dodge truck 1948-60 Eaton 1350 series 2 speed axle used in most 1-1/2 ton through 2 ton medium duty Dodge trucks...

I cannot read the model number on your tag.

[Greg698]

That looks similar.  Sorry about the pic . 

Serial # is 93253314

C1H  71 

I have no clue what any of this means , but learning slowly .  I idea was to find a rare dodge truck , restore and improve along the way. 

[Dodgeb4ya]

"C" means the series of truck... used from 1954-56

"1" indicates the year=1954

'H" indicates the tonnage rating=2 tons

"71"  actually "171" tells the wheelbase= 171"
