Full 2-way MZ helical rear LSD for the R180 differential across GC8, GDB, GRB, and GVB Subaru STI platforms, from the 1/2-way selectable range. All-phases lock-up in a helical design — the rear stays planted on corner entry under decel as much as on exit under power.

Multiple STI generations on a single part number; check your carrier housing size against R180 specs before ordering.
