:whs: If u tighten it up it might cause overheating and premature failure.

The fluid you ad is friction modifier, the more you add the easier it slips. It is used to prevent chatter of the l/s clutches.

The factory l/s unit can be tightened up (shimmed) with the possible side effect of faster clutch wear. It helps, but if I was going to all the trouble I would be installing a detroit locker. Factory unlock specs on the holding strength of the l/s is only 20 ft-lb, which is minimal at best, some are set up tighter from the factory by accident.

I played the "tighten it up" game a bunch of times and it's just a waste of time. First I tried to thicken up the shims, little to no difference. I then added a extra clutch spring to each side, this helped a little but not much. Ended up with a Detroit locker just like ALL my other truck. That 10.5 L/S is a waste of time. Sorry!

:whs: without a doubt, got a locker from Sean and will not settle for anything less.

This may be my next mod. The stock LS rear is a joke w/ the added ponies and torque. My only concern is how brutal is the D. locker when turning?

That rear L/S doesn't impress me at all. I've got a nice one-wheel-peel out in front of my house :( My Cobra lights up BOTH sides like it should

With the one wheel peal i heard adding traction bars can make it go away. my buddy put them on his 6 leaker and it lights them both up now.

Never heard of that as a cure. Tractions bars didn't help my rear light both wheels. The stock LS rear is easily over powered w/ the aftermarket tuning. Maybe its just my rear,(doubtful) and frictions are baked? If they are I think I'd rather just get a Locker and be done w/ it instead of having to nurse the stock rear.

I've got a LS rear(factory) dually and it lights both sides easy!! I've only got 16,500 ml. on it though..

There is a BIG difference between the 10.50 Ford Sterling axle found in the SRW trucks and the Dana 80 found in your dually. The Dana L/S found in your Dana 80 actually works!

For the front or back? And lubeowner, do you know of a driveshaft company in the Minnesota/Wisconsin/Iowa area that upgrades driveshafts and crap? I thought I saw you mention it in another post somewhere.

Back. I know of at least three trucks around here that run or ran them in the back of their pulling trucks and to date I have never seen one fail.

Driveline in Dubuque, Iowa. He builds most of the drive shafts for the pulling trucks around here.
