This is NEW Easy mount version which doesn’t require machining of spider gear to be fitted, so it is a lot easier for installation than before! 

Forget about the one-wheel spin! With our Progressive LSD Conversion set, you will no longer suffer from losing grip! The set is mounted on your standard differential transforming it into a clutch-type 2-way limited slip differential. 

The set is mounted on your standard differential transforming it into a clutch-type 2-way limited slip differential. 

No more one-wheel spin on start, and sloppy turns around the corner. With this conversion set, you will gain the true performance of a proper limited slip differential.

*Important note 1: before installation of LSD conversion set, please inspect inner surface of small spider gears. It is important that it isn’t damaged from previous usage. Needs to be smooth, otherwise it will cause premature wear of new central pin and possible break down. If it isn’t completely smooth, please take gears to machine shop to process the surface.

*If you are not sure about your fitment, please send us the last 7 digits of your VIN so we can check it for you.

The set is made from extremely strong s6 tool steel. Parts are heat-treated and hardened to 40HRC under the protection of argon to avoid deformation.

For friction shims, we use the same material as OEM LSD clutches to avoid metal shredding. Therefore, shims are perfectly safe for long term usage! Preload is provided with high rate springs, and we get a dynamic lock from 37.5° angled ramps. All of this together gives 25% progressive lock which increases with revs and vice versa.

All parts are made in the N7 quality standard.

*Professional installation is required. Use oil for limited slip differentials ONLY.

Instructions will be provided with the purchase of the product.

This is a completely NEW Design product, CLUTCH TYPE, PROGRESSIVE, NOT Phantom Grip Or Cheap Copy Parts From CHINA

Since we had a lot of questions about what the difference is between the infamous Phantom Grip or CHINA Copy Parts and our product, we decided to write them down.

Many people tried Phantom Grip or CHINA copy parts and left disappointed with the feeling that they had thrown their money away. Since our product looks similar at first sight, some of you are scared to try it which is quite reasonable.

We want to emphasize that our product only looks similar to Phantom Grip or CHINA copy parts and that’s where every similarity ends. Without any further delay, here is the in-depth explanation:

1. Phantom grip or CHINA copy parts locks a differential only by using high rated springs. However, our product has ramp angle on the central channel where the central axle passes through. This ramp angle provides dynamic/progressive lock exactly the same as OEM ZF LSD. When you press the accelerator, large gear attends to spin the plate around pushing the ramp of the central channel against axle increasing pressure several times more than preload.

Conclusion – Phantom or CHINA copy parts has a radial channel and relays only on high rated springs. In contrast, our product has both high rated springs to create preload, and a dynamic lock from ramp angles.

2. Everyone is afraid of metal shavings as a side effect of Phantom grip or CHINA copy parts which often destroys transmission in front wheel drive cars. Therefore we use friction shims between gears and plates. We use the same materials for friction shims from which we are making our LSD clutch plates. This material gives them high resistance and longevity.

3. Materials that we use in production are only the highest quality tool steel. We harden and nitrate the materials to achieve the highest quality surface finish possible. That gives our product the maximum durability and lifespan.

4. Our products have proven themselves on many race cars on Hill climb, Circuit, and autocross tracks. The drivers using our products achieved up to 5 to 10 seconds better times than personal bests with factory differentials.

關於 LSD 油選用?

MOTUL Gear Competition SAE 75W140

LSD (限滑差速器) 目前主要分為兩大類:摩擦片式以及蟲型齒輪式,摩擦片式 LSD 可以有效的提供傳動輪穩定且優異的性能,他擁有許多蟲型結構 LSD 所無法達到的特性,除了可設置起始 Preload (預載) 外、還可透過改變壓板扭力孔坡道角度來設置鎖定方向以及比例,循序漸進的鎖定特性讓車輛可以平順且穩定的隨著油門深淺來控制驅動輪的穩定性,不依賴車輪接地壓力差來觸發做動是讓這這類結構能全時發揮優異性能,更不會像蟲型齒輪形式的 LSD 會因為單輪失去接地壓力而直接解除鎖定。

除特定用途下(如飄移賽),摩擦片形式的 LSD 為眾多車廠在性能車款以及標準化工廠賽車上所配置的主要 LSD 結構,也是全球眾多比賽廠隊優先選用的 LSD 形式。

然而摩擦片結構的 LSD 需要使用專用油品來控制溫度、壽命以及性能,並且讓摩擦片在超過額定負載下能允許進入漸進式打滑狀態來釋放多餘的壓力,我們了解市面上有各式各樣不同品牌、型號、濃度的摩擦片 LSD 專用油,也許您不知道該如何選擇,所以在多項考核測試後,強烈建議使用來自 MOTUL 的 Gear Competition SAE 75W140 在我們所有販售的 LSD 組件上,他可以有效減少高鎖定率的自然噪音以及提供優異的溫度抑制,並且發揮 LSD 的最佳性能。
