Upgrading no-LSD diff to LSD one

[Mux213]

Snejk,

The problem is the axle itself, if you orignally have an open diff rear end you probably need to swap out more then just the diff, the axle is different.

Now I have to admit, I am not sure about the difference between an SR5 open diff rear end with drum brakes, which definately is a different axle then the GTS one, and a GTS open diff rear end compared to a GTS with LSD which might actually be the same and means that you can simply drop in an LSD. There aren't many open diff GTSs around here so

However you mentioned that you found an open diff, so the question is, what do you currently have on your car? You do not change the diff unit itself to LSD, you probably can throw away the spare unit you have bought depending on what you got on your car.

If you have a normal GTS rear end with (broken) LSD with disc brakes, good chance you simply either buy a new LSD unit and get it installed by a profesional (simply take out and replace the LSD, the trick is getting it adjusted just right so you don't mess up the RNP gears), or buy the whole unit with RNP installed second hand but they are hard to find.

SYM (USA), Max (USA) and Speed-inc (Swiss) here on the forum can get you a brand new LSD from several brands.

Owh, you have a zenki levin, make sure you buy a zenki LSD or it won't fit, kouki is slightly different size.
