Waaaaaaaaay Back in the Days, International Auto Salon

found a pic from IAS (International Auto Salon) back in… back in… when was this? lol 7 years ago? or maybe 8? i dont know shiets too ancient lol it was when OS Giken first came out to the US and Enonvativ Force distributing them.

IAS(インターナショナルオートサロン)での写真を見つけた。これいつだっけ…どのぐらい前なんだ…?笑。7年前とか?8年前?イニシエ過ぎて覚えてないわ(笑。OS技研が初めてアメリカに来た時だね。Enonvativ Forceがまだ卸してた時だわ。

Nancy, me, and Yuki.


damn, its been a long time lol


the aftermarket industry was doing MUCH better these days.


Gotta Organize My Office,

too much stuff in my office right now 😦

オフィスになんだか物が多すぎる 😦

OS Giken LSD cut model.


some random trophy.


love for GUNDAM 🙂 bought two Sazabi. one home, and one for office lol

愛ラブGUNDAM :) サザビーに関しては二個買った。家用とオフィス用(笑

Monday Day Off,

yes, monday we had a day off 🙂

そうなんです、月曜日はお休みでした 🙂

went toMarukai to have a lunch with Kana-chan. here at Shinsengumi.


see those gyozas on the right? mang they were cold!! wtf mang. how come it wasnt heated? the microwaves were broken or something? shiet. they even wroted on the menu “PANFRIED DUMPLINGS”.

右の餃子が目に見えますでしょうか?スンゲー冷めてたんだけど!!どうなってるわけよ。なんで温まってなかったの?電子レンジでも壊れてたのか?ったくよぉ。メニューにも書いてあったんだよ「PANFRIED SUMPLINGS」って。

after eating that cold gyoza, i went to Signal to get my differential oils change.


for all OS Giken LSD users, dont use Mobile 1 oils. they dont match and will make noises. OS does have differential oils at 80W250. let me know if you want them 🙂

OS技デユーザーの皆さん、モービル1のオイルはお勧めしません。オイル合わないし異音が出ます。OSでは専用のデフオイルもあります。80W250っていう。誰か必要な人居たら連絡下さいまし 🙂

gotta call from Kana-chan to ride along to IKEA, so i did.


we went to go get some seats for her nail salon which is the above, and was sold out 😦 we went to IKEA just for their frozen yogurt?? fail… hahahah

彼女のネイルサロンのためのイスを買いに。上のヤツなんだけど、売り切れでした :( IKEA何しに行ったかってフローズンヨグルト食いに行っただけ??やっちまったなぁー…ww

that night was a meeting the Reiko and Yuki at Tea Station.


Reiko deciding on the pics for to use on her business card.


my good old buddy Yuki is working on the photo-chopp’n process.


and look what i got.


huge lol

look what i found on the way.


i hate these. ugly.


and another stop to pick up shirts.


where? ICON!!


well, it wasnt ready yet lol i will go back tomorrow.


and now to i Logistics to pick up some OS Giken stuffs 🙂

さぁて、お次はiロジスティクスにOS技研の商品取りに 🙂

and now on the 2 freeway, heading to Chevy Chase Dr. in Glendale. why? cuz i got the OS Giken LSD installed 🙂 take it out for a drive.

そして、高速道路の2号線に乗って、グレンデールにあるチェビーチェイス・ドライブに向かってます。なんでって?OS技研のデフが入ったからこれから試運転も兼ねて峠で遊んでくるとこッス 🙂

arrived at Chevy Chase Dr.


and here i go!!


poooooooowerrrrrrrrrrr shiiiiiiiiiiiiiiiiftttttttt!!! lol


gotta watch out for deers,


and horse-riders.


cigarette break on the side 🙂 lots of people were here i guess… lotta skid doughnut marks.

横でタバコ休憩 🙂 結構人が溜まってたんだろうね…定常円かましたタイヤマークがイッパイ。

went to go get some gas now, changed my camera settings to Tv. and Rd. 2!!


poooooooowerrrrrrrrrrr shiiiiiiiiiiiiiiiiftttttttt!!! again, lol


i hate this turn… arghhh


hahahha i look so fast… lol thanks to the OS Giken LSD, the car feels much more fun 🙂 unlike the other LSDs, the locking is smooth. the car will have its head inward and turns with the accel pedal control. i will something more detailed soon.

ウケる、俺超速そうじゃん…笑。OSのデフに感謝ですねぇ。車が全然楽しくなったよ 🙂 他のデフと違ってロックがガツンって効かないからいいね。車はアクセルのコントロールで頭入る感じになってきたし。もっと細かい事はそのウチ書きます。

on the way back, found a dog sticking his head out from the window.


a fun Sunday it was.



OS Giken,

i was at,


Toyota Tsusho America, to pick up a OS Giken LSD for a customer 🙂

トヨタ通商にOS技研さんのお客様のデフ拾いに行きました 🙂

get back to work Mark.


Sean re-doing the initial torque and stuff. i use to do this too, so laborious… lol




IAS Long Time Ago

heres a pic i found from International Auto Salon 200…. two thousand… hmm cant quite remember. was it 2003? dont remember… yea Enonvativ use to distribute OS Giken. hahaha that was long time ago. picture with Nancy (to the left) and Yuki ( to the right)


OS Giken Limited Slip Differential

so why choose a OS Giken LSD? well, lets take a look at the picture below first.

and here is a random LSD i found online. i had to crop the name off since i will be talking shmack about it… lol hahahha well, i will save the shmack talking for later. please take a look at the picture below.


***Courtesy of Google Image Finder*** …lol

now do you see the difference? yes the number of the clutch plates, also known as the friction plates. OS Giken has twice the number of the plates inside the differential. and its springs in the pressure ring is to pull the two rings together unlike the others where it tries to keep it open as much as possible. with all the patent received mechanism, OS Giken’s LSD for lock 100%. below is the simple steps of how the OS Giken LSD works.


1.) the spring inside the pressure ring will switch from free to lock in split second.

2.) the drive force thats been flown from the engine to transmission will revolve the differential case, and at the same time, spins the pressure ring simultaneously.

3.) the pinion gears and the cross shaft will push open the pressure ring.

4.) the stretched open pressure ring will push out the pressure plates to lock.

5.) the pressure plate locks perfectly to rotate the side gear which is hot forged.

6.) the drive force will be transmitted to the drive shaft upon the rotation of the side gear. 


1.) プレッシャーリング内のスプリングがオープンとロックの状態を瞬時に切り替えます。

2.) エンジンからミッションを通って来た駆動力がデフケースを公転させてプレッシャーリングを回転させます。

3.) ピニオンと十字軸がプレッシャーリングを押し広げます。

4.) 広げられたプレッシャーリングがプレッシャープレートを押し広げてロックします。

5.) 確実にロックされたプレッシャープレートがサイドギア(熱間精密鍛造加工済み)を回転させます。

6.) 回転したサイドギアがドライブシャフトに駆動力を送ります。

one of the LSD out in the market is the same type as the OS Giken LSD since they use the OS LSD as for OEM. i’m not sure if they still do OEMs. i believe some people do know which company i am talking about. but still, the mechanism within the LSD is different. there is this one company that tried to make it like the OS Giken. not mentioning who though.. and this guys is the one i would like to bash on lol. here is how the story goes. one of the engineers went to this lawn mower factory in Okayama Japan with all the blue prints memorized (not completely though since he was doing minor works) and made a mock up of the differential. but of course the product was a complete fail. just kept on breaking. and yes they been doing more and more research. then one of te engineers have took all the tech info and started his own company. to fill in gaps of the quality, they used carbon fibers for clutches and differentials. not gonna mention who though… hahha this was long time ago. i bet some people do know about this pretty famous john dory in the industry. well, copy is only a copy even though they added their originality. they cannot copy the mechanism of their STSG (Spline Through Side Gear) and the LTCS (Lock Timing Control System). the number of the pressure plate and the diameter size is one and only from OS Giken. that is the reason why i recommend OS Giken LSD.

OSのデフと近い構造の物がマーケット内にあります。今はどうかわかりませんけど、以前はOSさんがOEMで卸していたので。知ってる人も多分多いでしょうねそのメーカーがどこなのか。でもやっぱ本物のOSの機構は違いますね。誰とは言いませんが一社似せようとした奴等が居ますねぇ。そこまで言いませんけどね(笑。話はこんな感じです。開発陣の一人が設計図を丸暗記して(完璧に覚えれなかった様ですねぇ)岡山県にある某芝刈り機の専門工場に駆け込んだらしいです。そこで似せたデフを作り始めたそうです。まぁ当たり前ですけど、失敗に終りました。それでも開発などを続けて行くウチに独立したそうです。技術の足りない部分は素材で補おうって事でカーボンを使用し始めたそうで。誰とは言いませんがねぇ…笑。もぅかなり昔の話らしいですよ。知ってる人も意外と多いでしょうねこの業界内はかなり狭いので。まぁ、所詮コピーはコピーです。OSの機構は簡単には真似出来ないでしょう。STSG(Spline Through Side Gear)やLTCS(Lock Timing Contorl System)とか。プレッシャープレートの枚数や直径の大きさはOSが群を抜いています。それが僕がOS技研をお勧めする理由です。
