Lift size question

Posted

Recently bought a 7 owner 2001 2500 for a overland camper project. It has a lift but I have no idea how big. From the center of the hubs to the bottom of the fender measures 26” front 28” rear (I think this is the scientific way to measure)  Any idea what size life she has? Appreciate it!

    I agree that is the best way to measure.  I don't know what size lift you got but I am 36" front and 36.5" back and I'm about 12" front and 10" back.  So just going by that I would guess that you are

    This is the stock 2500 rear blocks, 02 any way. Dont remember the height of the block but can measure later if need be.

    It's been a while since I've had them but I measured before and I think I remember measuring a hair over 4 inches...maybe 4.25ish?

 Did rams come from the factory with LSDs? 

Some did, like mine with a 4:10.

I'm a standard open diff, no limited slip. Prefer the standard diff over limited slip.

Ran into this exact issue on my jeep. Angles all messed up. Wicked death wobble at 55.

Never had death wobble or and steering slop. Always had straight steering and just a bit of free play in the wheel but that is how I adjusted the steering box.

LOL... Working with the wrong ladies. @Wet Vette loves my truck it looks stock and for her hips and back much easier to get into. (We are both in our 50's).

Haha...maybe so.  But I think I'm interested in something a little different you are and hence in a different kind of girl.  I like the shallow ones cuz they are usually not quite as intelligent and thus much less work.  And the kind of qualities I look for in their hips and back have nothing to do with their ability to get into the truck.

    Hard to know what I’ll need without the final weight in the back.

    You can go to Grangetto's in Escondido to weigh the truck before and after the build.  I think I paid $10 for an unofficial weight of my truck's front axle w/ 5th wheel,  both axles w/ 5th wheel attached, and 5th wheel alone.  Real friendly people there.

    You'll want to keep the truck....it will be easier to get the walkers in and out of the back.  90706452_animated-smileys-smaulis-0731.gif.7e48d5e0d036d76fa735b8f52348099a.gif

    I think you misquoted me there big guy.  It was Mike that said "We are both in our 50's" not me.  And he was referring to him and his significant other, not me and him.  Besides getting it completely wrong you nailed it. :punish:

     

    I'm in my 40's and don't have the wear and tear or battle scars of a married guy...so I still look in my 30's...which means I can still pull the 20's. :thumbup2:

    Mike is not married? Congratulations Mike!

    Yeah, im the one that mention we are in our 50s. 

     

    Next reason for not a lift as you get older it gets tougher to keep lifting heavy items into high bed or high cab. For me this one reason I bought the BigTex trailer its only 16 inches above the ground and goes off road too for firewood. Another reason giggle about lift kits, Im dragging my 16 inch clearance trailer off road. Truck got more clearance than the trailer, but I can roll large loacs without lifting.

     

    Yeah I know your only young once, enjoy life, im over the hill and starting to fall apart. Hips and lower back issues.

    Instead of Limited Slip Differential, you might consider an ARB air locker.  Best of both worlds -- open diff until you need it, then basically a spool when locked.

    Been looking at a few lockers for both my jeep and Ram. Really want OX Manual lockers but they don’t make them for a Dana 70. Bummer. So now it’s between air or electronic.

    That's pretty much what I found when I was looking at them.  The Dana 70 is kinda like the wicked stepchild...not much of a selection out there for them.

    Bullet,

     

    Just find a complete 80 axle.  They came behind manual transmissions in the 2500 series (so you get the single rear wheel configuration).  You are going to pay a bit more to have rear discs, since the rear disc was only '01.5 and 02.   Those would bolt right in.  I am unsure what happened with the 3rd gen axles but I can't believe they are significantly different.

    I’m headed to the salvage yard This week. I’ll keep my eye out. Do you really think it’s worth the trouble swapping in an 80?

    The only reason I mentioned it, was there may be a larger variety of different lockers for you.   I thought you were concerned that the locker you wanted was not available in the 70.  If the locker you want is available in the 80, it would help your overall picture just to upgrade to an 80 if you can find one. 

     

    Otherwise, no I wouldn't change to an 80 just for giggles.   In the SRW version they are not really that different.  just a bit bigger ring and pinion and carrier bearings.  Wheel bearings (and we think floater axle diameter) are the same on the 70U and 80 SRW.

    If the locker you want isn't available for a 70 it probably isn't available for the 80 either. 

    FYI - do some research on the e-lockers, they have a built in flaw that you may not like.  When going from forward to reverse or reverse to forward they will unlock for approximately 1/4-to 1/2 a wheel revolution due to the cam locking design (may not be a big deal for you).  ARBs are locked as long as air is supplied.

    Appreciate all the info. Unfortunately Ox doesn’t make a locker for the 70 or 80. Gonna shop around a bit. Still trying to figure out the best gear ratio and tire size. I’m working out my priorities for this build as well 

    • Owner

    Optimal final ratio should be 3.55 to 3.73. 

     

    Example stock mine came with 265/75 R16 tires and 3.55 gears (31.6 inches). Now drop to a 245/75 R16 tire (30.5 inches) not changes the final ratio to 3.69:1 which I'm currently running. When figuring it out you need to start from the stock design typically 265/75 R16 tires.

    Ive been reading through a few of your older posts that cover this issue. I found another more “in-depth calculator” where I was able to put in the 47re gears and see what rpm Is at what speed. http://Www.grimmjeeper.com/gears.html

    So I’m looking at Falken A/T3W 285/70r17 which are exactly 33” in diameter. With 3.73 gears the final ratio is 2.57. 70mph = 1834 rpm. Does that sound about right? What is the ideal cruising rpm for long haul gas mileage?
