I was looking in to getting a locker or limited slip differential for my 06 Ranger, and I narrowed it down to 3 that I can afford. I was wondering if any of you know the pro's and con's of each, and could reccomend one to get. I was looking at the Auburn H/P limited slip, Auburn pro series limited slip, and the Eaton posi.

 

if you're looking for L/S, look into the Ford TracLock. $255 at Summit and it's a whole lot better than the Auburn. Not near as many moving parts, simple as a clutch pack with a spring. Buddy of mine threw one into his Bronco II after he blew his Auburn up, says the difference is night and day.

 

yup, Auburns are garbage.

 

Ok thanks for the help.

 

for a limited slip you can't beat a detroit truetrac. It is a full geared limited slip with no clutch packs to ever wear out or have to rebuild. Keep in mind that with a limited slip it is going to need to be installed by someone who knows how to setup the backlash on the gears after intall because it replaces the carrier.

 

Oh yea I know, I would not **** with the gears by myself, I will leave that to my mechanic. I see your in Methuen, so am I. Where about Methuen are you?

 

right by presentation of mary, lived here all my life, you?

 

I have the Eaton Posi myself and I can say from experience it does a damn good job.

 

Lived here all my life too, right down 110 past the Whirlaway.

 

I finally bit the bullet and got a truetrac installed last weekend in my 7.5" rear end. Can't feel any difference on the street, its basically invisible except my tires don't spin on wet roads anymore. I tried it out on a dirt road and if I really jam the gas both tires spin equally. So it really works! I read on another site that it is engaged a little all the time, and it seems like its true because there is no clunk or hesitation.

I was attracted to the truetrac because like TireIron says above it has no clutches to replace and I had a stock Ford LS in a previous truck wear out before 100K. And the truetrac doesn't require any special oil additives or anything. It costs more than the ford one and about the same as the auburn pro, but installation costs the same for all of them. The only one that is cheaper to install is the Powertrax no slip but they don't make one for a 7.5. And its not supposed to be as smooth.

The guy who installed it only charged 3 hours labor. He was easy to choose--out of all the shops around he was the only one who had done it before. He didn't have to take out the ring/pinion so didn't change the pinion seal or anything, but he did need new bearings for the limited slip because he broke one swapping it off the open diff. All told the unit cost me $475 for the part (delivered) and $215 to have it installed (with parts and oil).

Can't wait to try it in the snow and camping in the spring!!
