they're M/T drag radials. why?

 

^^^ha^^^. my tahoe is 2x4 and doesnt have a prob with the boat. i wont put my truck in the water

 

The DTT doesn't use clutches, it uses gears. Failure of the LSD is not inevitable. The clips are intact and even if they come loose, there's no surety they'll do anything more than fall to the bottom of the pumpkin.

I can't see spending $1,000-$1,200 on something that's doing just fine. If the diff needs to be opened up beyond maintenance and inspection, I'll put in a set of 4.10s with the DTT.

 

Normally I'd agree with you 100% Mikey, if it ain't broke - don't fix it, unless you're moddin' it.
But in this case, WAY too many people have the stock LSD fail AND do damage when it does so. Not saying it's gonna happen, but I ain't too crazy about the odds.

Personally, if I had the means to make that one component a mod, I'd do it sooner rather than later...

 

Shoot, I can't even decide if I'd wanna get shorter gears. A little more jump would be fun, but I only put about 3,500 miles a year on it, almost all highway, north of 70mph.

 

Well, there is nothing saying you gotta do gears AND LSD. Although if the idea is to have both eventually, the labor would be a lot less doing both in one shot.

First year I had my truck was right after I got divorced so it was my only vehicle. Put 18k on it, then bought my Grand Cherokee mid way thru the following year. Truck averages 6k a year now and almost all of that is trips from Florida up to the farm. If I had to do it over again, I'da still done the 4.56s, but I'm running 35" tires. If it was stock height, I'd prolly live with the 3.92s it came with. Now if it had 3.55s, they'd be out of there in a heartbeat...

 

I'm curious about tires as well.

You can also look into siping your tires if it is offered in your area. There are a number of passenger grade tires (Uniroyal Tiger Paw comes to mind) that come with smaller tread blocks that allow each tread to move and grip. Think of a tread block as either one big finger, or 5 smaller finers trying to grab the same thing, as well as the 5 small fingers have more flexability. I live in Phoenix Az, so our local tire stores stopped offering siping years ago due to lack of interest. I have to have mine siped in flagstaff and shipped here if I want it done, or I have to do it myself. As we see here all of the time, everyone has an opinion, but I believe that the $7 per tire to sipe it more than makes up for it in additional life out of the tire as well as better grip in the rain and at the boat ramp. The only downfall here is that the siping does not reach the bottom of the origional treadblock, so as the tire wears the extra treadblocks from the siping will eventually dissappear. Tire stoers will not resipe when your tread is low. I have taken a modified Exacto knife blade and cut my own sipes. It really tedious and hand cramping, and it's hard to make the sipes look even.

Do a Google search on siping.

The video at the end of the DTT applying different torque values whilst on different surfaces is interesting.

First of all.....Thanks for all the replies. I love this forum.

I went to the dealership today and provided them with my VIN. Truck is actually fully loaded. Within the optional equipment that the truck has, it list CODE DSA and that equates to Anti-Spin Differential Rear Axle. Another interesting fact is that it already has CODE NHBP which is Auxilary Transmission Oil Cooler.

Now my question is.....The Anti Spin that is on my truck how does that compare to the Detroit TrueTrac? I am sure the TrueTrac is better. Is it worth replacing for my specific issue which is the boat ramp. Or do I just winch the boat up all the way up onto the trailer and just live with it?

Opinions are appreciated.

Thanks again!

 

I am also a fellow boater. My 98 Ram pulls my 20' cuddy out without any problems whatsoever in 2WD. I do have a 4x4, but never use it. Now when I first bought my boat I didn't have my truck yet so I borrowed my friends F-150 and I did have to throw that into 4WD because of his tires.

I have some beefy tread on my truck. I think that made the difference.
