New to the game.

What are the do's and dont's on using limited slip?

And what advantages/disadvantegas does it have over an open carrier?

I was hoping to find out that it would work for hills butI found out it doesn't so I'm all ears...

Advantage: It puts the power to both wheels, giving you better traction.

Disadvantage: None that I know of, except cost of the part and cost of installation.

How bout turning a corner? I thought I heard about spinning out. What about part throttle around a corner? Or should one wait to use the throttle untill the truck/car is straight...

 

That condition depends on the "posi" unit you select. Clutch/cone types (like OEM GM) are not good for road racing or taking turns under throttle. The way the "posi" works is by transferring torque to one side, then the other and back and forth (during slip conditions) ... basically if you are under throttle, your rear end will start to wag. Promoting a spin out.

Limited slip unit have no draw backs over an open.

How are Eaton's posi's? I like the price obviously. Any drawbacks over Auburn?

 

Are you working on a 1/2 ton truck or a third gen. The page for the 7.5 rear at Tom's is http://www.tomsdifferentials.com/cat38.htm

For those who don't know, I have a 63 Chevy 1/2 ton Stepside with a 12 bolt rear. It's not original, so I have to check the rear end tube (from what they told me) to check what year it is from and what it came off of.

 

Contrary to others posts, Auburn limited slip diffs are for road racing. With any car that has power, if you don't pedal a car properly it will spin out. Most people nowdays are too use to driving sofas on wheels- what I men by this is the cars with the ABS and traction control basically drive themself and noone needs to learn to trailbrake anymore in them.

Now put a person that drives a sofa into a car that doesn't do this and they learn real quick that they can no longer just stab the gas, stab the brake. They need to learn to pedal things properly.

With an open diff going around a corner, if you ease onto the power too much the inner wheel will start to spin and the car will not accelerate. With an Auburn, the power will load both rear tires properly and plant the car nicely coming out of the corner. Again if you just stab it, it'll come around.

I personally like the Auburn over the Eaton. I've broken two Eaton's over the years. Never had a problem with an Auburn unit. I also run a detroit locker (new style) on my Chevy truck with a 9" Currie rearend. That hits hard around a corner, more for street/dragracing than cornering.

 

It's a Hot L6 mated to a 2004R and it hits hard once the cam kicks in all the way to it's limit of 5500 upstairs...and that's skaten' with one shoe...It's pretty torquey(sp) down low too.

My brother and nephew are trying to get me to go to the 1/8 mile at Irwindale. Before I go I want to install the posi. I need all the help I can get. I hope it can get the engine to it's sweet spot sooner than the open does. It kinda takes a lttle while. I'm hoping it wil take off 1second ...That will be good enough.

Would it work for small hills? For those of you who have been to like Echo Park or Highland Park, areas like that where the hills are freaking steep! If yer haulin stuff and punch the gas to get to the top, will the posi help?

It's not a crazy torque monster so I think I'll go with a Eaton and hope it don't break. I'm on a budget since I will be tuning the chip . Need to save the pesos. Works tight right now.

In a word - YES.

 

Now that's what I'm talkin' bout.

I guess it's time to do it.

Thanks HOMETOWNS!
