BMW 188 / 188K / 188L Plate type LSD | Limited-slip differential

Plate type LSD for BMW  188 / 188K / 188L | Limited slip differential 

BMW  188 / 188K / 188L

Applications:

The 188mm differentials are mainly fitted to BMW E28, E30, E32, E34, E36, while the 188K differentials are found on E39, E53, E46 6cyl and more modern models such as E86, E90, E92, F2x, F3x are fitted with the 188L differential.

This is important:

We recommend using OE or fully synthetic Gear Oil with NO shockproof additives or friction modifiers, known as ¨LS” gear oils which are exclusive for plate type LSDs.

It is also recommended to add some Gear Oil to the LSD when assembling it into the gearbox. We use anti-rust oil during assembling in our factory, but it has no lubrication function.

Our Plate type LSDs (Limited Slip Differentials) are crafted from "FORGED" Nickel Chromoly steel and undergo special heat treatments such as Super Sub-Zero or Cryogenic treatment. Additionally, they are subjected to processes like shot peening and WPC to bolster core and surface strength, increase wear resistance, and extend service life. The high strength material, along with the processes and treatments used, not only minimize friction and enhance fatigue strength, but also contribute to significantly reduced overall weight and internal lubrication improvement, through the use of large windows and multi holes. As a result, our LSDs offer prolonged durability(in average, they don´t require any service during the first 2.000km of special stages) and improved and stable performance.

Technical specifications: 

These plated LSDs stand out as the sole product on the market featuring 16 friction plates design. In addition, they have the added value of being the lightest on the market, weighing only 5.6 kg. These features contribute to enhanced traction and consistent performance, with a stable preload value during a long time, even in endurance races.

As in all our plated LSDs, we use dual ramp bodies and our factory spec version on this application is the 35/67.5 & 35/90. Other ramp angles available upon request.

We include “free or charge” a set of ring gear / crown wheel bolts, made of high tensile steel grade 12.9, along with an extra and thicker belleville/conical washer for those who like to try with higher preload values.

As a proof of our quality and reliability, we offer 1 year of “motorsport warranty” upon material or manufacturing defects in our full range of Plate type LSDs.
