locking diff option not??
I'm getting my options together 4 ordering and just wanted to know if I'm not seeing a locking diff option.Will there be a locking diff available?
What is the fords so called "traction control" on the 2008 SD (new idea or not)?
Thanks.

When I ordered my '08 350, there was no locking differential, only limited slip. I think that GM is the only one with a locker.
As for DSC, that's a computer system that intervenes when the vehicle is going into a slide (i.e. not in the direction your are steering it). It either applies power or braking to bring the vehicle back in line.
Check out this article on Wikipedia that explains what it does much better than I can.

Did I ask for info about the 06 duramax traction control? NO!(EATON)
buzz off
I asked about the "2008 SD"

LOL the gov-loc is a POS! it only locks when it detects a 300RPM difference between the 2 drive wheels. that means that youll be on the gas when you want the locker to engage, causing a huge shock when both axles lock. and the gov in the 10 is known to be a bomb.

I thought the new powerstrokes just had traction control, and not stabiltrac. Both of which are different things.
I didn't post to brag or to start a pissing match. sorry sheesh. BTW i thought it just applied the brakes to help keep from spinning not to to actually control the vehicle like the stabltrac does.
FYI, it is 1.5 turns of a rear tire before the locker locks on a max and it won't engage at speeds over 30 mph and I have never heard of 1 breaking unlike the limited slips. But when a locker does break, you have nothing, when a LS goes out you just have an open diff. Advantages and disadvantages to both.

ok buddy. even the most diehard GM fans(besides your self) agree that the gov-loc in the 10 bolt is a straight up bomb just ticking away.
i will give you that, i was off by 200RPM.
if a basic limited slip can withstand more abuse than this "locker", then that doesnt speak much for its durability at all. not to mention, most people who build up a GM into an offroad truck(for some reason...) trash the gov-loc for a REAL locker anyways. your basic ratchet autolockers are better than those damn things.

The smaller designs are fairly weak and the 8.5" and 12 bolt truck designs are especially weak. The 9.5" and 10.5" 14T units are fairly strong and will hold up well to towing and moderate abuse. The Gov-Lock is designed to act as an open differential during normal driving with no force being applied to clutches. This fact that no force is applied to the clutches keeps the clutches from chattering during normal every day driving. When either wheel slips and spins approximately 100 rpm faster than the other a governor assembly senses the difference in speed and activates a ramp system. The ramp system causes the clutches to engage and transfer power to the wheel with traction. One other feature of the Gov-Lock is that it will not engage at vehicle speed above 30 mph. This no lock-up feature keeps the vehicle more stable at higher speeds where both wheels spinning could cause an inexperienced driver to spin out or slide off of the road. This is a great design in theory and works as designed in a stock vehicle that is not abused. The problem is that most of us modify our trucks and many of us abuse them. When this unit is asked to deliver under extreme conditions it tends to self-destruct. The force generated by the ramp system that is used to lock-up the clutches works well, except that same force has to be contained by the case and the case is not always up to the job. (factory)

while i see what you are saying, I have never and I do mean never seen a locker go out even at the many truck pulling events I have participated in and also watched. There are many duramax's with well over 500rwhp that have never blown a diff lock out, but I don't know of many people that make a diesel and extreme off road vehicle.
Day to day durability can be debated either way, but the average 4x4 barely ever goes off road. LOL

no, the factory rear end stays just as it is, where i know some ford guys that have to rebuild the limited slips because the hp chews them up. we also put e lockers in the front diffs when we pull.
IMO it is a toss up, depending on how it is used. If the locker is engaged before high wheel speed is incured, the locker will generally outlast the limited slip. But for engaging at high wheel speed, the LS will be more reliable (long term) but also require more maintance. GM's locker doesn't engage over 35mph, so the hardest abuse on it is limited. But with a limited slip, it works no matter the speed. That can be an advantage, but also cost more in maintance.

sorry I don't remember. after searching, I see you are right. Sorry. So chalk up one.
BTW I read more on the traction control on the duramax even if know one cares, it is relative, because all it does is allow the vehicle to start out in 2nd gear rather than first. This is something ford has had for years if I am not mistaking. Maybe now they are just calling it traction control, and not changing anything but advertising it more.

Alrighty then, back to the topic. When I was at SEMA in early November, the FORD Engineers urged me not to get the Traction Control package. According to them it is an ABS based traction system that senses slippage in a wheel brakes that wheel.
I guess it and places the power elsewhere. Sounds to me like this is for the soccer mom SUV types driving a Super Duty IMHO.
I like to have the control myself, I don't need to have some computer telling me when to brake or accelerate.
