How can i tell if i have light or heavy duty axles

 

You have a dana 60 front and the rear is a D70 if you have an automatic or a D80 if you have a 5 speed

No light duty axles with the Cummins

 

ok cool thanks

 

can anyone explain why my truck has a D70 front ?

i was thinking it was a D60, but an "dana expert" read the number on it as a D70, but it has all the stock spring mounts and 4link mounts...

 

Is your dana expert an expert or just someone who says he is

 

He is... i compared my front axle to a friends truck, my axles are way beefier...

he has D70 rear compared to my truck has D80...

 

Some older Dodges had D70's I'm not aware of any 2nd gens with 70's from the factory but maybe it's an overseas thing

 

Price any gauges yet? I might drive to anchorage Friday if I can get a dyno appointment. Going to see if I have broke the 300hp/600torque mark yet. Underground performance has a dyno. I have the d60 front d70 rear with 4.10 gears.

 

haha, i was so intensively aspired to get to know this...

contacted all previous owners, first owner upgraded the front axle to a D70 for towing reasons, not sure what he was towing but i guess he felt the need for a stronger axle..

so nobody needs to worry that their 2500 has a D70 up front, hehe...

D80 rear came stock... guess it's because it's a manual...
