No Spin and Shift on fly??

[DocDetonancour]

Most lot rigs have the no spin. Why would anyone want it? Won't it pull the rear around on slick stuff? Howe about the shift on the fly? Is it worth $600? How fast does it engage? thanks, Doc

Must be a regional thing - it's hard to find one around here without the limited slip option. I wouldn't even consider a truck without - 4x4 or not.



As for "on the fly" - Come on!!!! Real men have STICKS. Its a bit of a misnomar that you can't shift on the fly with the manual transfer case. I believe the manual tells you not to attempt above 40 mph.



The electronic engagement is just something else electrical to worry about (In my opinon)

 

[Mopar_Mudder]

They are both "shift on the fly" one just has an elect motor instead of a stick.

The reason that the "anti-spin" option (limited slip diff) is desireable is because it can help you get unstuck, and do so without the penalty of a locker. Especially desireable with an empty truck on a slick surface...



It still lets the outside tire rotate faster than the inside tire in a turn (its still a differential) but when you're stuck and one wheel just spins (getting you no where), the anti-spin will transfer some torque to the stationary wheel.



remember that a 4x4 with open differentials is really only 2wd (one front and one rear wheel) and if those happen to be on slick surfaces or in the air, you don't move.

Doc,



The anti-spin was mandatory on the 4:10 and the AA version actually works. I have the Laramie and have both the anti-spin and the electronic shift and am very pleased with both.

The anti spin works pretty well, too well sometimes, with the stiff suspension and the anti spin the truck gets sideways when it's wet very easily. I will be putting it in 4 wheel as soon as there is any snow at all on the roads.

The 4wd lever takes up space on the floor, I prefer to mount radios there.



The AAM LS is the best factory diff I've had. Very nice. Would'nt own an open diff truck ever again. Use less go power if your fish tailing! Let off and it will straighten up. Or go and buy an open diff and let that right rear tire spin and spin and spin. I can only imagine what cummins torque would do to a single tire on wet pavement.



What I hate the most about my old open diff truck was coming to a stop on a slick hill with a load. In the rain I needed 4wd at an intersection in the Emory area or I had to ride the brakes to keep from sliding backwards. Empty that truck would spin tires even with a light foot. Forget pulling out fast in trafic. My dad's open ford is the same way. The LS trucks had zero wheel spin on the same hill/red light. I'll never have an open diff again.

agreed, for the Autos. I looked at a 6-speed with electronic xfer case and didn't like the interior presentation. They take up that floor space with a console/cup holder thingie that is a waste.



so for 6-speeds I like the manual xfer case the best and ordered my 04 accordingly. the manual xfer case is just as "shift on the fly" as the electronic one is.

I prefer the limited slip diff in my trucks, although I've rarely needed it. Those who launch at steep wet boat ramps usually rave about LS's, and a boat has been in my near future for years.



Off-road, a LS can more easily get you through the rough stuff, but so can proper use of the emergency brake.



For me, the LS is just too inexpensive not to get. Isn't it something like $125? For that little bit of a cost, it definitely seems like I get that much use out of it.



The push button 4wd, on the other hand, didn't feel very necessary to me. I don't need the floor space, and I like to grind the gears myself. Plus I know I won't accidentally shift into 4wd like happens occassionally in our Suburban, which has the same feature. I don't think I've ever accidentally shifted the lever into 4wd.

My Cobra wx75 fits under where the transfer case shift stalk would go. I find the console pretty handy for smaller items. After you get used to it, the cup holder works pretty well, too.

Thanks guys. Sounds like the anti spin is popular. Doesn't sound like many would spend $600 for the "anti-spin". Doc

 

[DLeno]

I'm confused as to where the $600 comes from. anti-spin itself is not an expensive option, but are you thinking of the "offroad group" which includes a 4. 10 LSD, skid plates and tow hooks. What exactly is the option that costs $600?

 

[SSage]

I've spent $600 on diffs before. Well worth it on my 4x4 farm/trail trucks where true lockers really help in the mud and on very rough roads. When the factory LS's wear out, the selectable lockers go in. I put a full time Lock Right in my 98, not good for towing but makes a good budget locker for trail rigs with mild tires. Cost less than $600 installed.



The factory limited slips are a steal. Pick up a 4x4 magazine and check out the prices on the diffs.

$600

Sorry for the confusion. The $600 was what the local dealer had on the "shift on the fly" option. sound like most wouldn't buy it? Thanks, Doc

I'm hoping mine is just a fluke. One day I pulled out onto the main road, a little heavy on the throttle. Next thing I know, the tackometer pegged and the inside rear tire broke traction & spun like crazy. I thought I smoked LS unit, but when putting both tires in gravel or mud and hitting the throttle both tires spun equally. Yet when leaving a stop sign, light or whatever (just a normal pull-out, not flooring it) and making a right or left turn it always felt like the inside tire wanted to go. A few weekends ago my wife took the truck out run a errand, and cutting the corner in my folk's paved driveway too tight (go figure), one wheel stayed on the pavement and the other splattered a 20 foot strip of grass & sod on the side of my truck. The wheel on the pavement didn't break traction, but the other spun un-checked. Later that weekend, we went to a family reunion where everyone had to park in a grassy field that was on a slope. Unfortunately a heavy rainstorm came along. To make a short story long, it took 9 guys and some 2x10 planks to get the front of my truck out of the hole it dug. While the front tire was tossing mud balls, I looked back at the rear tire and it was just sitting there waiting for a ride. If this unit couldn't hold up to a SO cummins, what's going to happen with the HO's...

You slide side ways, same as every body else. My truck was the perfect truck off the lot (for me)... with the exception of the LSD.



I bought it anyway. It is easy to cook one tire with the open rear. If I have the truck long enough I will outfit it with electric lockers if and when they become available.



It still goes very well with a trailer in dirt, simply because of the weight. If it were to loose tractions though, you would be stuck, where the LSD could make the difference.



If I could I would get the LSD but for me it did not kill the deal.

Just remember that both xfer case options are shift on the fly. That is, you can shift the manual one while rolling too. The core mechanisms of each transfer case are identical -- just that one has an electric mechanism to operate the shift, versus the manual shift lever.



I wasn't worth $600 to me, but I have a 6 shooter. I got the 6-spd because I like control, and I passed on the electronic xfer case because it didn't fit conceptually with the 6 speed nor cosmetically in my opinion.



I actually think its a great option for the automatic transmissions, just my opinion of course.

 

[Jaylor]

After reading the posts regarding the "electronic shift on the fly" option. I'm thinking maybe I don't want it (dependability issues) However, my ordered truck is in "BX" status, is it possible to delete this option or am I too late and hope it works right ?????

 

[SMorneau]

I didn't see where anyone mentioned it but with a LSD (I have one) you will tend to go sideways much easier than with an open diff. It's great when you want to slide around a corner with the tires squealing! You will be able double your rear axle traction.



Now the downside. Your diff lube will not stay clean as long and when you are on off-camber ice situtations your rear end will go sideways when you break loose. With both tires breaking traction there is nothing to hold the rear of truck on the hill. They are not the best in all icy road situations. If you let someone drive your high torque truck with a LSD who doesn't know what they are doing odds are good they will put your truck in the ditch in icey conditions or at least have a lifelong memory of your truck.



My unloaded std cab truck has virtually no traction in 2wd in the snow so I really don't think the LSD helps me very much (2 x 0 = 0). I would order it for sure but I wouldn't pass up a truck only because it had an open diff.

 

[Briman]

Joe, yes, it is too late to do anything about it except turn down the truck when it comes in. I for one (along with others on this board) really like my electric transfer case. I think you will like it as well. If you do a search you will find many positive posts regarding it. I forget what the other guys are calling it. Dial a drive or something like that.
