Torque Lock LSD (1 Viewer)

[CruisingSned]

Has anyone had any actual experience with torque lock LSD’s? Working through options for the rear of my HZJ105 with not so fantastic Mr Toyota LSD. It’s being setup as an over lander to tow a camper trailer. Can’t seem to find a lot on them.

Don’t need to be told I should buy an e locker or air locker, plenty of opinion threads out there

Thanks

No experience with that LSD...though it looks to be quite strong. The Toyota unit is rough looking..but robust. It works O.K. but needs quite a bit of wheel spin before it actuates. Any 'original to the vehicle' unit is no doubt in need of new Friction Discs and maybe the 'steels'.

Since you are 'down under'....you might contact 4x4 World there. They might be able to shed some light on the various LSD's.

The Toyota LSD is a clutch type LSD and the Torque Lock LSD looks to be a Torsen type LSD.

Clutch LSD: will have lockup when a tire is in the air but wears out over time. The clutch lockup action will work all of the time.

Torsen LSD: will spin a tire when it's in the air but will never wear out. The Torsen lockup action only works when power is being applied and gears are turning AND both wheels have at least minimal traction.

Just curious if you are unsatisfied with a current LSD why not get an air or E locker?

@CruisingSned i was asking bc if you are currently unhappy with the LSD why take the time and expense to put another one in?

LSD's vary widely in design, performance and longevity, so swapping one for another could definitely be a move up . There are pro's and con's attendant with LSD vs. Locker (full time or select-able) but there are definitely conditions where a LSD might be the better choice for a person vs. a locker.

That's fair enough. I'm on night shift at the moment. Brings out the patient sparkling side of my personality.
Looking at expense versus result. I like the idea of an auto/lunchbox locker but not 100% on noise/change of driving characteristics.
The LSD is considerably cheaper than an e or air locker
Hoping someone had installed one. The only review I found was someone who was doing fully sick burnouts in a Commodore.

I have one of these in mine, its the best thing I have done to it, don't have to think about it just got traction all the time, also got a torsen in the front, lock the center diff and it just drives up pretty much anything where the tires can grip with zero fuss, even with a wheel in the air the ATRAC hardly activates

Would love to get specs on that locking diff @CruisingSned . Like @flintknapper mentioned, you may be able to get more info from down under. I have searched all previous years of LSD thread related topics and they get burden with all the locker nonsense. If we can get insight to what type of locking LSD, 1.5 way/2 way, helical, etc that are available for the rear axle, it can shed some light to the 98-99 folks that don't have atrac and don't want a locking diff. Especially since pricing has become even between the 2 options. Great experiment to those that have ATRAC but anyways, I have looked into LSD type transfer cases like those on the 200 series and was wondering if that could be more beneficial and cost saving vs having the open center diff / transfer case we have currently. I feel like that could benefit the 4WD dynamic of all years as well as being of help to those who have ATRAC a tiny bit more.

I am also curious about that front LSD you are talking about @03SaharaV8, that sounds very interesting. I'd imagine a Torsen style LSD + ATRAC would work way better than a clutch LSD only and maybe even better than a clutch LSD + ATRAC based on the way a Torsen diff works. But once you're in there you might as well just install lockers. One use-case where a LSD would be better than lockers would be for a sand dune or race truck where speed and handling is important.

No air lines or wires and cheap are the main points.

They are always working, lockers you might use 1% of a track these are on all the time and make it all very comfortable set and forget low range and just drive, no clunks bangs or axle wind up. for me if all diffs where the same price i'd still go the Torsens.

I ran a LSD when I rebuilt my front diff approximately 4 years ago. I didn't mind the heavy steering. Would be a viable option if converted to part time potentially. Ultimately lasted approximately one month before the carrier broke where the axles slip in. Luckily it didn't ruin my brand new ring and pinion, and do to budget constraints at the time a stock carrier went back in.

 

[ClassyJalopy]

What LSD are you guys running in the front diff?

Bwell, was it an Auburn? You inquired about these in a previous 2016 thread.

 

[bwell]

This was it. Once again definitely cannot recommend unless you have converted to a part time kit.

Back in my Rover days, front and rear Detroit TruTrac LSD's were a somewhat popular option in the Discovery II. My understanding was that the LSD and traction control complimented each other well. Never got to drive a rig with that setup personally, but it definitely peaked my interest.

A full time locked Detroit rear with TruTrac front was another popular option. I don't know if either of these are an option for our 100's, however.
