The stock torsen is always sending more power to one wheel or the other.

A TRD LSD can essentially "lock" both wheels to be even.


A TRD LSD costs $950.

You don't see them used much, as $950 can buy alot of better things to help your car go faster, if that is what you are after.

I'm pretty sure Jay Marks Toyota sells them for around that price. Also Toysport had them listed on their web page at around that price under specials or something.

Don't forget that the TRD LSD will essential "help" keep you from hitting the wall a bit...I do believe.

Instead of one tire spinning more, thus pulling you to one side....both would spin...kinda keeping you straight....or so i hear.

Torsen is on a few N/As.


The only drawback to the TRD LSD is that it may lock going around a corner. It's more suited for straight drag use, not road race.

I do not think this is correct. A torsen will apply a torque split to the drive wheels. If the torque split exceeds the Torsen's maximum bias ratio, the torsen will lock up, trasnfering all power to the most loaded wheel. I think Kent Rafferty had this problem in low speed autocrosses, and drag racers have this problem running slicks. AFAIK the torsen is preffered in road racing.

That is incorrect. I spoke with Jeff Watson about the TRD LSD unit last week and he gave me a price of $850. There are also some extra misc. parts that will be required so you can count on it costing closer to $1000 without labor. Labor could run you another $500 if you pay a competent shop.

I believe that you are correct, Grant.

I just looked on the Toysport site and its listed in their Kazuma parts specials at $715. Maybe its old. Also someone else posted they were selling it at ~$739. Then again maybe these are old or incomplete prices because you need other additional parts.
