The RS LSD uses a spring technology which keeps differential noises to a minimum, improves durability due to the clutch plates enduring lower pressures, and better lap times from low power loss for any vehicle. With Cusco’s long time development of LSD’s, they have been able to produce top quality LSD’s for a wide selection of different vehicles. Cusco’s extensive LSD knowledge and experience has produced some of the most versatile, durable and effective LSD’s on the market. In addition, some LSD’s can be changed between the different Way configurations for the best results in different race applications.

Here is a description from Cusco explaining the differences between the differential types available for the aftermarket:

One way LSD – specially suited for front wheel drive cars and 4WD car front axles. Activates under acceleration, and acts as a true LSD when the throttle is off. A great chance for improved lap times. A CUSCO original design.

Cusco LSD – Type RS: The Cusco Type RS LSD had proved to be capable of competition use in the All Japan Gymkhana Championship without overhauling a single time during the season. With all drivers and teams finishing with good or championship results at the end of the season.

According to Cusco’s in house research, initial torque is 50 to 70% lower compared to the conventional cone plate type LSD enabling lower drive friction and better response.

* Low power loss means better lap times for even the mild tuned of cars
* Chattering is kept low
* Improved durability as clutch plates are low pressured
* The LSD efficiency is higher with smoother oil flow between plates.
* Special precision springs, set in the pressure plate, assure steady coil movement
* Clutch plates do not stick together like conventional cone plate type LSDs. Therefore less clutch plate wear or deterioration occurs.

There are three ways to set your Cusco Limited Slip Differentials: 1 way, 1.5 way and 2 way.

* 1 way LSD: Specially suited for front wheel drive cars and AWD front axle cars. Activates under acceleration, and acts as a true LSD when the throttle is off. This CUSCO 1 way LSD will improve lap times without a doubt.
* 1.5 way LSD: Activates under acceleration while the under-steer under deceleration is less than on a 2 way LSD. Recommended for those who have a hard time with under-steer.
* Two way LSD: Recommended on rear wheel drive cars and AWD rear axle cars. Activates on both acceleration and deceleration. Recommended for those who prefer aggressive driving and big angle drifting.
