Mine never had a hiccup at the track. Foose also runs one. And based off experience here, id say the trutrac is much more commonly used then the eaton lsd
Simple reason for that. Monkey see monkey do bull ****.

Good to know.

I'll be installing a truetrac, its got great road manners and I simply prefer the torsen like diffs. I've had clutch based LSD which worked OK as well, but the chatter in tight turns was annoying. I also don't want to worry about more things to wear out.

You gotta know how to "use"? the trutrac. In a tight spot you can get them to lock up quickly by lightly applying the brakes with throttle.

I'm an expert, I've watched youtube videos.

The trutrac has impeccable street manors, dead quiet, and holds 1000 hp at the track. What more do you want from an LSD?

They don't lock up.... ever..... they can't. They don't have that capability unless the thing welded itself together for whatever reason.

As far as the comment about Foose having no issues with one.... read this:

They are an internet Koolaid thing like a lot of other stuff.

This guy has 2 in his 4x4. They look locked to me. Are we speaking of different things?


He also does what I talk about, light braking to get things locked up.

They shift power..... they don't lock.... they physically can't lock. Look at the design of how they work internally which is available on Youtube too and then get back. If they do lock it's because the worm gears have welded themselves to the carrier somehow..... They need the brake action and thus friction to try and shift power from one tire to the other...... at which point you may as well install individual wheel brakes and just use an open diff lol. They work pretty good in a front axle application because they let you turn nicely like an open carrier but I would never, ever, install one in the back unless I was road racing or something... which is the primary application they were designed for lol.

Watch that video a little more closely..... neither of the opposing side tires are actually turning at the same rate of speed... one is slower than the other. That does show them working but no they are not "locked". Yes guys doing burnouts and whatnot will almost always get 2 wheels leaving black as they constantly shift power to the wheel with the most resistance to turn... provided both tires have at least some resistance in the first place. One on ice and one on pavement they peg leg.. until you jam on the brakes and hopefully make it shift.

Limited slip differentials do NOT lock if one tire is loaded, they are the same as open diff. Ask me how I know:

No offense, but if you took your best 1/4 and mine, and equalized weight between your full blown racetruck and my essentially stock truck on 20s up front, you would have at best, a 0.5 second difference. I've got a pile of timeslips and a couple pounds of caked rubber on my bedsides to show that the trutrac gets the job done for my application and hasn't given a simple wimper, despite twisting a hardened aftermarket axle and snapping DS in half.

Well, you're high sided on the frame, I don't think any diff would help. FYI watch that vid. A little brake apply gets bothw wheels going.

Back to the pic, how in the **** did you do this?!
