Nope. Only the Power Wagon has those options but it's not IFS. A rear locker is your only possible option but it's not an easy thing to get. I only have seen one guy over on DT whos had a rear locker in his 1500

 

If you find one for an AAM 8 1/2" front axle (which GM also now uses in their 1/2 ton trucks), let me know. I'll buy it that day.



Actually, the Power Wagon uses the same 9 1/2" front axle that all the 2500/3500 Rams plus the 1500 Mega uses. Any option for the Power Wagon would also work in those.

I personally know four guys with a true locker in the rear of their 3rd Gen 1500s (non-mega cab), plus one who welded his spiders (which also locks the axle). All four have a Detroit Locker, but I'd not recommend it for a daily driver truck. Every one of them ratchet pretty bad on pavement when making turns...

 

I just knew like the 04-08 F150's can have the eaton e locker or arb air locker for the front diff so I just assumed they would have developed one that would work for our front differential.

That blows that they dont. Any reason why they could develop one for the aam 9.25 but couldn't find a good way to develop one for our smaller aam front diff?

 

Too much R&D and not enough demand? That's usually the case

 

If it was enough demand for the 04-08 F150 crowd, and us and chevy are using the same front diff so they could kill 2 birds with 1 stone, I dont see how not enough demand could be the reasoning. (now the F150's are using a slightly different style rear 8.8 as their front diff so im assuming it was alot easier to develop one for them, but still come on.)

Acourse when you email them regarding the topic you get a shotty bs answer at best.

 

i have been thinking of doing 4:56 gears how much is involved in doing the front and rear ? do you need and specialty tools for the install?

 

Its a fair amount of work and yes you need specialty tools.

Its one of those things, that if you need to ask you probably shouldn't be doing the install.

Now if you have alot of tools including the specialty ones such as whats needed to properly set up the gears and inch pound beam style torque wrench for your pinion bearing preload, have plenty of time to just let it sit and take your time while you drive another vehicle, and/or have a friend that has done it before than id say go for it.

But if not especially the tools and time part, then id leave it to the professionals and have a warranty to go with it.

 

As far as our discussion on the air locker or e locker for our front diff, I ended up emailing arb about it all. They kind of gave me the bs answer that you'd expect and said that the demand isn't high enough sorry but I wasn't happy with that. So I called them and talked to them on the phone about it all.

My reasoning was the F150 of the same era has one and even though the 8.8 is used in alot of applications, IMO the aam 8.25 is used enough to warrant one.

Not only does dodge/chrysler use it but so does GM, for many things, not just the silverado/sierra lineup. Plus they would be able to kill 2 birds with one stone that way and hit both market brands with one thing.

He called me back later and said they looked into it and discussed and decided long term they will make one for the differential. They are currently making setups for other axles that worldwide meet a bigger demand than just Ford/Dodge/Chevy in the US and they serve strictly based on what the highest demand is for the world first.

While its a popular setup here in the US, the other 100 countries or more that they serve; it is basically non existent. But he can't say for sure when it will be released. It could be a few months or it could be next year, they just honestly can't say at this time.

But hey atleast they are working towards it, just might be awhile.

 

Don't hold your breath. I had the same discussions with both ARB and Auburn at a 4x4 truck show way back in '08 and got the same replies...

 

Yeah I assumed so but figured id try and hope for the best.

On a side note, my 06 4x4 that I just picked up has the LD rear 9.25 which I assume is the open diff. Why they put the LD open diff option for the rear of a 4x4 is beyond me but if I want to switch out to a LSD, do I just need a new carrier and rebuild? Or does the whole rear differential need to changed out?
