Description

The Cusco Type-RS Rear Limited Slip Differential for the 2015-2019 Subaru WRX uses coil springs between the pressure rings to deliver initial torque, producing a gentler, smoother engagement than conventional cone-plate LSDs with minimal chatter and reduced clutch-plate wear. The unit engages fully under acceleration and partially under deceleration as a 1.5-way, and it can be converted to a full 2-way setup by rotating the center spline, with clutch pack order and spring tension fully customizable to suit the driver.

  • Cusco part number LSD 183 L15
  • Type-RS: 1.5-way, convertible to 2-way by rotating the center spline
  • High-tension chrome-molybdenum steel housing and gears
  • Large oil windows for increased lubrication flow
  • Fully customizable: clutch pack order and spring tension adjustable
  • Designed for the R160 rear differential only - not for WRX STI (R180)
