Gear Ratio - Pre 1934

[30DodgePanel]

Does anyone know of low gear solutions for pre 1934 vehicles? 

 

As an example, specs for 3/4 trucks say 5.63 or 5.11 depending on a few other factors but was a lower truck gear even an option that anyone is aware of? Excluding the 1/2 ton models...

Also, what were the options for passenger DB's prior to 34?

I've read that the Senior was 4.54

For others that may be looking for info on gear ratios. 

If some of you guys that own passenger cars recognize any interchangeability or the same ratios used in cars please comment so we can know.

 

 

Off topic (oh no, Dave's going down another rabbit hole) note the proof for the 3/4 ton 124" continuation along side even the 1933 models. Sure wish Chrysler Museum would help out with answering what the last U or DA 124, 133 , 135 and the 185 were, but I'm not holding my breath.

 

 

Feb 1933 ad showing the initial Chryco body style post Graham Brothers still in effect just before the 1933/34 passenger car styling took prominence. 

Model charts have the numbers for these trucks ending in Nov 1932 (making them 1933 models technically). Also note the wire wheels on the Chryco panel truck. 

Ads like these are why I've always argued why it's so important to understand when your truck was produced, especially during any carryover lineups. The two in yellow are carryovers into the 1933 lineup. 

 

Most of you truck guys who have followed frame numbers know what this means. For others  that don't and are curious just ask and I'll try and keep it brief.

U124, DA124, U133, DA133, 135, and 185 continued after the cutoff date for 1932 models of July 1st for 1933 new models.

The more I see the more it proves out the serial or frame number sequence in chronological order. It is a shame that they couldn't have seperated the model charts by frame number for each model, but it is challenging and fun figuring it out. The ad above tells me they must have still been making a 1 1/2 ton and 2 ton and both appear to be 150" wb which I've highlighted in lime green below. All of these trucks were still being produced after the July 1st deadline of 1932 as 1933 models. A primary difference between the 1930/31 models were the lack of sun visor.

     I don't know about options but my 24' is 4.16-1.

I am not sure there were options for cars, but I think different body styles got different ratios.
