Yea he hit it on the head with more detail than I did lol. The best you can hope for from a stock truck is a 4x3 haha. But hey it's still better than being stuck with a RWD like me

 

Exactly lol but even with an open diff up front, its still a million times better than a 2wd truck and even with a open front it is usually more than enough than is ever needed unless you are constantly offroading alot. But for things like snow or normal uses of 4x4, the open diff up front isn't to bad atleast thats my experience here in KY. Obviously we aren't having 30 ft a snow a year like other places but we do get a fair share of all around uses.

Just the simple act of having a front wheel helping pull the truck vs just the rear trying to push is truly a night and day difference. You can be stuck in 2wd in snow and just sitting and spinning. Put it in 4wd and jush barely push on the gas and you will just walk right out like nothing even happened. Its almost retarded how much of a small difference the front pulling makes a difference.

 

Its actually from my buddies 07 1500 4wd.When he got it a while back (on my recommendation) He called it a "heavy half" and I thought it was a 2500 too becuz there was no 1500 badge on the truck just the RAM logo but he emailed me his build sheet and it had alot of HD components on it. But its rated a 1500.
Isn't Chryslers marketing wonderful.

 

It has to be a Mega Cab then or the build sheet is wrong because a 1500 would never ship with a 10.5" rear axle

 

Oh ok so RP is worth the money

 

RP or Amsoil are good for the diffs and tranny. I think most synthetic brands will have it in it already but you can always check the bottle or call the company directly

 

Good call

 

I know the rep from amsoil always had me buy the additive for my rear diffs so just keep that in mind for amsoil.

 

Might as well just put it in there whats it going to hurt, when i replaced my rear end the guy told me poor design by dodge plus no additive change so ill just be safe and put it in

 

Well to much additive is and can be a big deal. It can cause the limited slip to not work correctly or even at all plus it can decrease the resistance/viscosity as well as how it performs against oxidation resistance of the oil. Obviously I assume it would have to be a significant amount to affect things drastically but if you had an oil like RP that was already made with it in mind, then you add 2 bottles of additive because that's what the manual calls for with some specific vehicle; then you could have a problem.

Some aftermarket lsd's and lockers recommend against even synthetic oil because it can affect how their clutches work and how it was designed. Im sure gear driven ones probably aren't as bad.

You just really need to check with the manufacturer of the oil or fluid you plan on using and what they recommend for your vehicle or what the manufacturer of your lsd or locker recommend for their product if you have an aftermarket setup.

Like stated Amsoil wanted me to use additive in mine even with their synthetic fluid but not the same amount that you pick up at the factory. They actually had a separate one that they developed and had a big difference in the amount in the bottle. While alot of Royal Purple people say it specifically states to not use additive with it because it has already been created with that in mind as well as a few other brands do that.

The best is to check for your specific setup and brand your going to use.
