there is the factory clutch pack limited slip diff, this is ok if you put fresh clutches in it or wind in a bit of extra preload.

Lokkas are legal but you are unlikely to enjoy the driving experience.

any reason why you don't want an Air Locker? are you aiming for street grip or offroad ability?

cheers

Go for air locker, either on or off!!

There's always the toyota factory electric locker, mainly found on 80 and 100 series. You'd have to change the whole axle.

this hilux diff is in my gemini (not my 4x4 )..

want it to be nice for street driving and curcuit work.. able to handle 250-300hp at the wheels.. iv heard the factory clutch LSD arnt very strong in this kind of aplication? or is that just a myth? i woudl assum 4x4 abuse to be more punishing then street/track thrashing.... in a 1000kg vehical

The Lokka will work a treat on the set up you have. What motor is in the Gem ? 300 hp would be a weapon .

air locker is ideal. leave it open for mild street, then lock it up for strip/circuit.

yes the factory clutch pack is weak but that's nothing to worry about, 300HP will shred hilux crownwheel and pinion easily. If that is really the sort of power you are running perhaps consider a 9.5" diff from a landcruiser.

I still say you will not be happy with the street performance of the lokka, especially in the wet - they are esentially a spool with the ability to allow one wheen to turn faster than the driven wheel, but if any slip is detected at the driven (ie inside wheel in a turn) then it will lock instantly - if this is a road vehicle, imagine squeezing the the go pedal a bit in a corner in the wet and instantly having no traction as both wheels spin. tops.

air locker might not be the best for cuircut work, could cause the rear to break loose easyer then a conventional LSD.. air locker would be perfect for drag racing tho

not changing from teh hilux diff now. spent to much getting this one set up for the gemini already.. theres a lot of mazdas and dattos runign the hilux diff with similare and even more power the this, runing under 10second passes.. so there must be somehtign out there that there using to tuffen them up (crown and pinion)... might have to ring around some of the "go fast" shops

yeah the LOKKA does sound a bit iffy with the how "locking up when u give it some power" could get dangerous on teh street

do the new hilux (2001, 2002, 2003 etc) clutch LSD's fit inside the older diffs??

I would look into a Detroit series 4 softlocker it has the similiar theory to the lokka but it delivers the end result a lot better. I think it would suit your needs perfectly. My vehicle does not make the hp yours does and I find the open diff of the Airlocker to be a pita on the street at times.

booflux, ill check out there web site and have a read
thanks

anyone know about the above ^^^ ???????

I've got a Hilux LSD for sale if you need one.

is it just the standard clutch style one?
what ratio? or is it just the LSD part?
price?

Gday
The lsd centre holds the ring gear stronger than an open centre,with two wondows in it.... go an lsd, and put some extra spacers in the clutch spring if you need it to be stronger.....torsens are ok, but do suffer i hear from stripping their worm gears...the lsd and washer under the spring will give you strength cheaply. Stay away from the auto lockers.

yeah after reading the about the auto lockers ... they sound a bit sketchy..


i found a 2002 LSD center hemispher thing.... will this fit inside/replace the open planetry gears my early hilux diff?

anyone?

Detroit make an LSD called a Truetrack and i have heard they are far better than a standard LSD.

that true track looks pretty good.. .. from what i read its a mechanical LSD.. not an auto locker like the others

might look around for some prices

i'd say the hilux diff will handle the hp because the car is so light. i'd be gettin an lsd and shiming up the clutch pack. you might have to pull it out a couple of times to get it just how you want it. would not even consider an auto locker.

I knew of a guy who had one in the front of his GU patrol and it worked really well and didnt affect his steering too much.

the truetrack has my vote for sure, but i came across a supra torsen center yesterday and bought that

same as this
