I have a '90 K5. "Peg leg" on front and rear. I would like to go with posi in front and rear. I'm by no means a hard core off roader. In fact, by the standards on this site, my truck would be a "show" truck. It's mostly on the street other than during hunting season. I'd like to have all 4 pull though- like everyone else.
2 questions:
- Am I correct in that an Auburn will enable BOTH wheels to pull at all times, but when turning the clutches will slip allowing the wheels to turn at different speeds so if I put Auburns in both front and rear I'd have true 4x4?

- If this is incorrect is there a diff. that will allow both wheels to pull without being a full locker? I don't know if a locker's lack of street manners might be more than I need.

Thanks.
 
I like my Lock-Right on the street , I only have one in the rear since for now mines full time 4x4.
 
The only thing that will absolutely make both tires spin (on each axle) is a locker or spool. A limited slip can "slip", hence the name. That's what gives it good street manners and ok offroad manners.

It depends on your terrain. Posi's are basically worthless in the rocks but they do pretty well in the mud and snow.
 
My terrain will be mud. No rocks at all.

So is a Lock rite a locker? Seems like it would be hence the name. If it locks how does it have good street manners?
 
A lock-rite is a locker, it has even worse street manners than a detroit (though mechanical lockers aren't all that bad on the street IMO).

If you want posi's then go for it.

Do you have stock axles? If so, I would recommend the Eaton posi.
 
Yes I have stock axles. So you think the Eaton would be better than an Auburn? I thought Eaton made the stock posi's?
 
IMO if you want a LSD front and rear. Detroit Truetrack is the best way to go. Treutracks are prolly the strongest LSD made.
They are a gear type with no clutches to wear out, Dont need maintence, except lube changes, They use regular gear lube and dont need friction additive.
They are the best choice for the front because. Clutch type LSDs tend to wear faster when used on the front axle. Truetracks perform well offroad. They are just there and dont get in the way. by using your brakes to make them work and put traction to both wheels they can perform almost as good as a full locker.

If price is no object. Then Eaton E-lockers front and rear would be the ultimate set up.
Total axle control by just fliping a switch. You can run with 1 or both axles locked as needed. Or open for the street.
How much are you looking to spend?
 
If you have lots of $$$$$ theres the air or elec lockers .That way your locked offroad and open onroad. Or the elec LSD/locker , its a LSD until you hit a switch it becomes a locker..

agreed
 
Well price is definitely an object. Like I said, my truck is a really nice K5. There aren't many that are as nice. I have owned the truck since '92 and have really babied it. I use it to tow my camper, boat, 4 wheeler, and basically carry my family here and there. I don't do alot of off roading but when I hunt I will get in some mud so basically here is what I need as reasonably priced as possible: good mud traction (preferably all 4 wheels pulling) AND good street manners. I've had Auburn, Detroit Tru trac, and Lock Rite suggested to me by some of my friends that supposedly know their stuff.?? Fortunately I've had some of the same suggestions here. I am amazed at the different responses. For instance, one post points out the great street manners of a Lock Rite, while another post points out that a locker (Lock Rite) does not have good street manners. Makes it difficult to make a decision when you are a rookie.
 
I have ran lockrites front and rear. I can honestly say they do not have good street manners. They are a good cheap locker that does what the manufacturer says.
"Provide good offroad traction." peroid. On the street they are noisy, bang, pop and pull left and right when you get on and off the throttle and chirp the tires when you go around a corner. Some people think that is cool . But I really dont like like the way a lockrite makes my truck handle.
No Slips are a whole different thing... As i said eariler they are a good streetable locker. But they do cost more. When you get into the 400 dollar range there are a lot of other choices.

I ask you again ?????
How much do you want to spend???
I have given you 2 very good choices in my previous post. Believe me i have been ther and done that. Even got the tee shirt.
Traction costs money. How far do you want to go?
 
I'm in the same boat, except I'd not call my truck a show truck...I don't try to test my capabilities in it, it's a tool to get me around in the woods during hunting season and the summer.

A true-trac would be my choice in your case. An eaton posi is second. Auburn's are not rebuildable nor adjustable, the eatons are. IIRC, an eaton posi however is pretty pricey for what you get, which is why the Auburns are likely more popular in the aftermarket.

You don't need a locker unless you tend to get a wheel completely off the ground. There can be some legitimate argument with that, but unless you are wheeling hard, the downsides to a posi or true trac are minimal.

No way I'll end up with a true locker, I like cornering hard, and I drive enough compact snow/ice to know that it would hurt more than help me.
 
I'd be willing to spend 400-ish per axle. I'd like to keep it under 400 if I could. I don't plan on any wheels coming off the ground. If that happens I'm definitely somewhere I don't want to be. My thing is that I have a Polaris 4 wheeler so I know the advantages of having all 4 wheels turn. I may not need that often, but when I do need it, I need it badly.
 
So how much can you get the Eaton or True-tracs for? I'm sure Summit sells them...

My gov-lock in the rear seems to be behaving itself for now, until it goes I'm going to stick with it.
 
IIRC truetracks for 10b are right at $400 each. But then you have to set them up
Are you setting it up yourself or paying someone to do it?
I dont think you can find an Eaton or Auburn LSD for under $400. Might look on Ebay.
