I just found out that my Dak has 3/4 ton leaf springs out of an 06 Ram instead of the original ones from the factory. Since I picked the truck up a couple weeks ago I noticed it rode really rough. I finally had time to take it back to the dealer. That's when they informed the previous owner modified the leaf springs to handle a heavier load. Followed by the 3.9? gears. The bad news... 265/75/16's, hauling heavier loads then originally intended and swapped gears ALL on a V6!!! phew... just had to let you all know, anybody else heard of anything like this, or have these leaf's or gears?

 

3.92 gearing was a stock available option on our trucks, not sure about on the V6 though. Haven't heard of anyone swapping in leaf springs off the 3/4 ton, seems rather excessive to me as the 1500 springs should have still been a step up.

 

That's what I thought.. it is more or less like putting the 3.7 into a 2500?!?!? Oh well, I guess it's a "unique" upgrade. I wondered why my truck has some "zip", it was because I thought it was the 3.55...

 

Is the rear sitting awkwardly high? I would image it would be with a 3/4 ton leaf pack...

is the leaf pack the same length or something...it just bolted right up??

 

No the the rear end isnt that much higher. 35 inches in the back and 32.5 in the front. not that much difference. The leaf pack is 7/8 of an inch longer than OEM.

 

Count how mony bolts you have on the rear diff? I want to get me some 3.9 gears

 

Oh, that wouldn't be too difficult to bolt up at all. This is actually good to know if anyone wants to make a Dakota Heavy Duty if they are big on towing and hitting that max payload.

 

Did they use different shackles on those leaf springs? Could ya take some pics too please.

 

mmmm i wonder how much sag the truck would get... sounds like a good idea... but a v6.. wow when i was reading i was thinking u got the v8 and was like sweet...then read v6 and then was like dam that sucks... but 3.7 have sum power for there size.. good luck with it. if i find a ram springs... i might grab em lol

 

Sorry I have yet to get you guys pics. Been working 12 hour nights, six days a week. After I get out I barely feel like doing anything lol. I will get pics up ASAP,hopefully today if not, tomorrow at the latest.
