hey guys i have a question for you i am going to be buying a traction adder for the rear of my 98 chevy blazer now should i go with a limited slip or a locker. It is a daily driver, but i wanted someting better then open diffs. I would be driving in alot of snow and offroading alittle on the weekends nothing really major. I was looking at the detroit trutrac or the detroit locker really don't know what would be best for me do you guys have any ideas, and is there anything i can put in the front of my truck for added traction.

oh man... you opened a can of worms now! [:D]
Tell me what type of wheeling you'll be doing... will it mostly be trail rides? Or, will you do more of the rock-crawling type stuff?
Also, regardless of what is said here, there is one universal truth to running a limited slip, it is undisputed and cannot be argued... the clutches WILL wear out and the "limited slip" will eventually become no better than an open carrier. So, when you drop $400 clams on a limited slip carrier, just remember that every time you turn the corner, the clutches slip and wear out a bit more. I've seen them privde traction aiding assistance as long as 2 years, and as little as 6 months (street cars are not included in this thread) and it all greatly depends upon the amount of street driving, how heavy you are on the throttle, tire size, etc. Also remember that limited slips are designed to provide a bit of extra traction, but under load, are absolutely designed to "give way" and allow the tire with the least traction to spin.
So let the debate begin... ding ding! [B)] |

| I will mostly be using the truck for trail rides no rock climbing or anything like that and i will be using it for driving in the snow,rain,mudding. It will also be a daily driver for know. It has stock tires but i want to go alittle bigger maybe 31x10.50 with a lift the reason I asked about limited slip was i thought lockers were not any good in the snow, What would you get? How do lockers work in snowy conditions? |

You're right... Lockers are particularly tough in the snow and will cause your truck to fishtail pretty agressively.
A Detroit TruTrac is a great alternative (I run a Detroit ElecTrac (essentially a TruTrac with the option to fully lock)) up front and swear by it. The great thing about the TruTrac is that it normally functions somewhere between a limited slip and an open diff when you're driving around normally. But, when you need to distribute power evenly to both tires, you simply modulate the brakes when giving it a bit of gas.
What happens is this - when you apply both brakes and throttle, the worm gears that run horizontally around the circumference of the carrier try to screw away from the center, and bind the differentiating gears together via sheer force, thereby locking the differential and poviding equal power to both axles. It's actually a wonderfully ingenious, yet simple design that works very well. It's only drawback is that under hi torque instances they can grenade. Big motor + heavy right foot + big tires + deep gears = explosion. I've never actually seen one break, but I've heard of it (you know how that goes).
If you're conservative on the throttle, this may be a wonderful option for you.
If you want the best of both worlds and don't mind dropping a bunch more money, then go with a selectable locker (e.g. ARB, Electrac, OxLocker, etc.).
For what it's worth, a TruTrac in your truck will hold up very well to 31's. I'm running 35's with a 400 HP motor and still haven't broken it, but I'm really easy on the throttle too.

| I have to back up what Webby has stated. I live in Alaska and know a thing or two about grenading a rearend or two(k maybe more). The Electrac is great as is the ARB, just know that you DO get what you pay for. Rule of thumb. And Ox makes a fine product with warranties to prove it. I know that you are runing a 10 bolt in the rear (please no debate...lol), and those are notoriasly weak(from the factory). And that only gets worse with bigger tires. BUT!!!, you will only be running a 31, so...no worries. Just take care not to have too heavy a foot when you get your locker, otherwise you may be writing to us about which axle or how to fix. Look Rick, I didn't get into the ring!!!! |

| I will tel you another reason that I do not like lockers in snow. I slipped off the edge of a friends driveway a few day ago plow (he had had it repaved and there was a 3 to 4 inch lip that was not there last year) Both right side tires were off drive and spinning a bit (ones on drive were a tiny bit too) while try to crawl back up on slick driveway. If I would have had a locker it would have pushed more against my efforts to crawl out because the push on the high side would have drove it toward the yard more and not helpd tires in rut to get a bite to pul out. The off drive tires needed to spin a bit and bite so there was balanced forward pull to get it back on the drive which it finailly did and it did not destroy yard either. I am not say that there is not any application for lockers, what I am saying is that they are far from a cure all in slick snow and ice situations. I do agree that the best possible setup would be a selectable locker that locks when you want it to, not when it wants to. |

Well lets put it this way, if you go to Eatons sight they have how to instuction on have to install a Elockers and they are using a GM 4x4 with a 10 bolt rear axle which you have.

Yes you do, I am sorry I get kinda stuck on when a blazer used to be a fullsized SUV. They really should have changed the name somehow when they shrunk it. |
