It does not lock it by any means and is nothing like a welded diff ( I have 240 friends who weld their rear end, horrible way to gain traction unless your a strictly drag car). It works the same way as a traditional clutch type LSD, the difference being instead of several clutch discs being compressed to introduce friction for better traction this produced the same result using 2 solid blocks of hardened metal pushing on the splined driveline gears instead. The result is about 90-95% as efficient as any quaife or Kaaz but at about 1/3-1/4 the price. It is not AS good as them ( I would not expect it to be considering the price difference) but your paying an awful lot more for that extra 5-10%. I did considerable research on this before I dove into it so I am not worried about any metal shavings or anything regarding the operation of this unit. Daily driving you don't even know it is in there until you start getting on the gas. Considering the level of power my car is pushing and the abuse I just put this through yesterday I can say with great enthusiasm its well worth the money and yes I do consider it a poor mans lsd and a damn good one at that. Just went out today in the pouring down rain and I can almost pull all the way through 2nd without spinning (when I do spin its both wheels) before this I could drop my car to 3rd doing 60 and I would break loose and hit the rev limiter lol .

Happy to answer any more questions about this. I was very skeptical when I came across this option when I got serious about finding an lsd option so I read every thread, reviews and anything I could find on it and sifted through to find the BS and the legit info

 

Talk to this dude here ^^ he was a major help to me to make sure I had the correct fitment and answered all my prep questions quickly and thoroughly.

 

Thank you for the reply and taking the plunge with this for people like me. Like you said, the price point made me a little skeptical about this. And you are an auto crosser so I know that if you're happy with it it must be fairly effective, that's a pretty good endorsement. Does it recommend any different weight/type of gear oil or just the stock fluid? Have you come across any other users and what the lifespan of this type of unit is?

 

So is trfguy the one who sells these? I see you referencing him as the contact.....

I really need to find out if it will work 100% for us Automatic guys as well....I really want this if it does....

 

That's another bonus. Unlike clutch type lsd that needs special fluid to keep the disc's conditioned. This does not, I did go with synthetic this time but stock weight. I have read a couple horror stories about people shredding their spider gears from these. HOWEVER not a single story gave detailed information on their story, everything was pretty vague which as far as I am concerned knocks them down some in their credibility. I read plenty of threads with people using them for years with no issues at all and still going, and all the detailed threads I read on this gave high ratings on their effectiveness, durability, and reliability. Anyone I found that seemed legit (mainly meaning I found various thread they posted on unrelated to this and found them to be genuinely knowledgeable on anything they replied to) either had first hand experience with it and praised it highly or they admitted (like yourself) that although it seems sketchy they could not approve or negate any claims since of course they had no personal experience with this.

 

You can buy them a lot of places but yeah I suggest Ryan from TRF, if for no other reason then the fact that he not only sells them but has first hand experience installing one of these in the Lancer transmission.

This is their site

I think you will find this little slideshow a good testament to their intimate knowledge of the lancer lol

He built a 300whp lancer for a member on here too zbailey
I have read his thread but for some reason my computer is being a ***** and wont load so I can copy the URL lol

 

Sweet I'll check it out and get in touch with him and see what he says about it.

 

Wanna throw this up real quick too. Just got it in the mail today. Much better IMOno more crack in the cluster finally.

 

call the dealer and ask if the PN for the diff is the same as the manual?

 

Unfortunately I cant give you a 100% yes but the fsm shows identical parts in an exploded view of the auto trans diff. I cant imagine a different differential for the auto

 

WTF


03...Like the new gauge

Ryan...thx. Mitsu will be able to give me a def answer

 

Kinda wondering the same thing???

 

prob trying 2 bump his post count
