This is a brand new, never used Cusco 1.5 way Type-RS differential for 89-98 240SX. This is the more expensive version of the Cusco differential that is supposed to keep chattering to a minimum. I installed it in my case but never drove the car. I made a bad decision and decided this type of differential is not for me. I need a grip type differential more suited for circuit racing.
More information on the Cusco Type-RS vs their lower range Type-MZ.
