Does A 4WD Truck Need Limited Slip

[ramffml]

You are entitled to your opinion. The places i am talking about needing to turn TCS off is not a parking lot, there are zero Honda anythings there. You need clearnace and horsepower as well as 4x4 or you are going nowhere.

If your driving pavement and good gravel, sure LSD is optional. It is inexpensive when ordered new, but you can get away without it 99% of the time. Mud or snow up to your running boards, no longer optional because TCS both applies brakes and cuts power, neither of which works well when navigating 30 miles of wet, snowy or muddy, deeply rutted road. On those roads an open diff is a big handicap.

I've already said many posts ago that offroad is a somewhat different story (and in the examples you gave I'd actually want a real locker, not the LS). If you are burying your running boards or regularly driving in spots that ordinary traffic can't go, then that would qualify as "offroad", don't you think?

Why not argue for 38 inch mud terrains? How about winches, are those a requirement in your mind? Front lockers? 4 inch lift? Why not push him in the direction of a powerwagon? One can always make up more and more demanding situations to justify better equipment. If that's how you want to argue then go for it but if you read the OP's original question its quite clear that LS is absolutely not a requirement.

Get limited slip. It is a real cheap option new and a REALLY expensive option to add later. No upside to open differential in the rear. Whether you need a locker up front (limited slip on the front is a BAD idea) depends on how much off roading you do. Mostly pavement, not needed and not usually a factory option on most pickups anyhow.

Same hold true of getting the right gears. 4:10 are a $100 option, swapping them later is a couple of thousand. Order the truck exactly how you want it, moding them later is very expensive. Guys that complain about the cost of options packages have never paid to do the add-ons later.

I was the second guy to answer the OPs original question. Answer above. The discussion moved a LONG ways from where it started. Most threads evolve, this one did too. I think a lot of great info got shared in here.

At this point, I don't think there is much more to be added or said on the topic of LSD so I am moving on to other topics.

Wouldn't have been the same if he wasn't wearing the jacket

Well it looks like it will be LS for me. I found a new 2023 2500 Laramie about 200 miles from me. This dealer seems to order all the trucks for the lot the same. L/S ,410, protection group, Level 1 option, tow hooks, towing technology, performance tuned shocks (whatever those are) and spray in bedliner. A person of course can order other options if you want something different but they have/had a variety of these in different colors and interior. As mentioned above this topic got a bit technical but I got the info I needed for my climate zone. Thanks again for the education.

Looks like a dealer that knows how to order a pickup properly for performance rather than for show. Glad you found what you are looking for.

I agree. He is located in farm country west of Sacramento. Probably has a lot of business from them and then pulls people from the burbs as well because he doesn't have a glitsy showroom. The salesmen are in a portable trailer but the lot is huge and full of 1500, 2500 and 3500 trucks. There is also a shop there. Same family has been in business for over 80 years. Can't say I got a killer deal but I did get 5K off MSRP. That's good in this state (of confusion).

I haven't tried to buy a truck since the pandemic, but we recently bought my wife a new Telluride. We looked at them 1.5 years ago and dealers were asking $10k OVER list. This summer they were asking $3k but we settled on $1500. So I would say that you got a Good deal, if not a killer one.

We got my wife a 2022 Telluride new for $45K. Great vehicle.

...it's torque that spins a tire, not horsepower.

This is where you are going off the rails.

Torque is only a force. HP is force x distance/time.

Put 100# on the end of a 1 foot long bar that is perpendicular to the ground and anchored so that the fixed end cannot move. Like on a lug nut that you've already set to 100 #/ft. The torque is there for eternity, even though the tire is not moving.

Now, if that lug nut is attached to a wheel/tire that is in contact with the ground, and there is little enough resistance that the wheel will start to turn, you then have HP. If you maintain force perpendicular to the bar, HP is the result and will vary based on how fast the wheel turns and how much force is applied.

An open diff (apart from extremely small, generally unmeasurable differences due to manufacturing tolerances) will ALWAYS apply equal torque to both wheels. It's physics 101. Ok, maybe 102.
