Fits select 1987-2011 Mazda RX-7 and RX-8 models (13BT, FD3S, SE3P) equipped with manual transmissions.

The OS Giken Super Lock LSD (MZ101-HA) is a premium mechanical limited-slip differential engineered to solve the traction limitations of factory rotary drivetrains. By utilizing a high number of friction plates and a patented pressure-ring design, this unit provides smooth, progressive engagement that can reach 100% lock-up under load. This translates to significantly improved corner-exit speeds, more predictable mid-corner balance, and eliminated wheel-spin during hard acceleration.

  • Designed specifically for manual transmission (MT) Mazda RX-7 (Turbo II/FD3S) and RX-8 applications.
  • Superior friction plate count ensures maximum durability and better heat dissipation than standard units.
  • Predictable performance replaces inconsistent factory viscous or Torsen differentials.
  • Precision-machined internal components for quiet operation and long service life.
  • Manufacturer Part Number: MZ101-HA
