please identify my zenki t series lsd

[cooter]

hey all
im wondering if anyone can identify this lsd that came out of my te71 levin with a zenki t series disk diff.
im leaning towards it being the oem lsd as it doesnt lock hard and has the old skool toyota symbol next to the OG but yeah just want confirmation. ive never seen a standard unit







also sorry if this sounds a bit stupid but the gears running it are 8t pinion and 39t crown. that means 4.87:1 ratio yeah?

cheers for any help

Looks like a TRD one from what I remember, OEM ones have like a rounded corner inspection window.

Also, I believe the crown wheel should have the ratio stamped on it somewhere on the side.

[cooter]

yeah the crown has 8/39 stamped. id be pretty stoked if it was a trd unit cause it turns out the other trd unit ive got is a kouki. but this one looks nothing like the other

[cooter]

just for arguments sake heres the other one. now bare in mind i dont know that this one is definately a trd unit as when i bought it i also got told its zenki but my axles are real loose in it but still go in. so i dont know whether to trust that info.



cheers

My bad, I think I got that around the wrong way. The rounded window is the TRD and the one installed is the OEM unit.

Edit. Yeah if the axles are real loose, it could be a kouki model. I got hit by the exact same thing a while back also.

Correct.
First picture is an oem (rubbish) lsd, the trd 2way is the one you want.
Make sure its not a kouki though if your diff is in fact a zenki

[cooter]

yeah it is a kouki as ive had a bit of a look through the forums and the axle sizes are only slightly off which is why the axle is "loose" in the trd unit. just wanted to make sure it was also infact a trd unit

dont spose anyone wants to buy a kouki trd lsd?? lol

cheers for your help guys

its OEM. there are kits to overhaul/iprove them but its not really worth it these days. 2nd hand aftermarket LSDs are pretty cheap now.
