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.

1.5 way LSD - Activates under acceleration while the understeer is less than on the 2 way LSD. Recommended for drivers having difficulty with 2 way LSD understeer and one way LSD braking.

Two way LSD - Recommended on the rear axle for rear drive cars. Activates on both acceleration and deceleration. Recommended for those who prefer hot driving action and big angle drift.

These differentials have the option to be interchangeable between 1& 2 way, 1.5 & 2 way Please select the switchable combination that you would like and the initial way setup.
