Cusco RS Rear 1.5 Way (R180) Limited Slip Differential Subaru STI 2004-2014

Featuring high-tensile chrome-moly steel housing and gears, the Cusco LSD is ready for some serious competition. With large oil windows for increased flow and Cusco's original groove-cut tech for improved clutch-plate efficiency, this diff ensures stability and longevity.

The coil-spring tech offers faster, smoother engagement and higher durability than other setups. Plus, this LSD is completely customizable so it can be tailored to the end-user's exact preference. It can even be changed to a 2-way by rotating the center spline!

Cusco's RS diffs utilize springs to absorb some torque, minimizing chatter and extending the life of
