Hey all, i took my suby for a bit of a bush bash today, and ive realised that it does need one thing, an LSD. but the thing is, i really dont know much about them and i've had a skim through the website and see theres all different gear ratios. I have a 88' L series, EA82 Carby. Part time 4WD(HI&LO).
what would my gear ratio be? and what car would i be looking to get a LSD from? and what process is involved in it? is it a big job, or not too bad.
I mainly want one for a bit of offroad purposes and going on the sand. cheers, any info or knowledge would be great as i'm clueless on diffs or what itd take to get and LSD going in my baby.
cheers.

Most probably you have a 3.7 (You can look on the back of your existing diff - it probably says "3.7". You can find an LSD from an RX L Series - all of which I think are 3.7 - unless they have been modified. They are a bolt in swap as well.

I have one in my L Series wagon - its great on the sand.

thanks for the info mate its greatly appreciated, did you have much trouble finding yours? whereabouts did you pick yours up from and what sorta price would be reasonable? cheers mate.

LSD diff are starting to get a bit hard to find now....you will pay anything up to $500 for one....average was about $300 mark

yeah theyre getting rare these days. Its a relatively easy swap too, just need some muscles haha.

where are you located? i might have my 3.7 lsd for sale soon.

wellll unfortunatley i'm located in NSW, lol which is a bit out of the way. but i'd be more then happy to organise some sort of freight and pay a bit extra for the hassles if one was to come for sale

Indy - my first one was $370 and the second one was $440 (which I begrudingly paid from a wrecker). People know what they are worth - and Datsun guys love them too coz they fit in their cars.

Your best bet is try to asking on here.. or go the wrecker option.

Hey can any one help PLEASE
I have a 7-86 L series RX Retro fitted EJ20t 3speed auto (Manualised)
with a 3.7 rear diff i belive to be open (with the rear jacked up i can spin one, the other is stationary)
My quiestion is can i get seme 4.44s diffs for it as I have not seen anything about changing ratios in autos ,how hard is this and is the ratio in the auto the same or could it be different.

If you've got a l series 3speed auto, 4.44 won't be doable.A ej auto with a 4.44 is .

Ta what is the lowest for an l series please
i need a good 1500 rpm so i need a real ratio change
and have spent some serious money on this box so sort of need to stick with it

all L 3sp auto's were 3.7 front diff. Some had a reduction in the rear transfer that gave you a 3.9 rear but the front was still 3.7.Maybe get a bigger stall on the converter.What are you trying to achieve?

There's always the welded option - I've just done mine and am very impressed so far!

Mick... just a little bit of useless info that is locked away in my brain cells... RS Legacy AUTO from Japan had 4.44 ratio as standard (Australian non-turbo auto was 4.11). I'd be asking some of your local Importers or someone on this forum if they have 1. You would need to use the Crown Wheel and Pinion Shaft to make it work tho but not retro'd into a L. Series auto

Sorry to jump in on someones thread
