Product Details

The Cusco LSD 431 F2 is a Type-RS mechanical limited slip differential engineered specifically for the 2016+ Mazda MX-5 Miata ND5RC with manual transmission. This rear differential features a 2-way configuration that activates on both acceleration and deceleration, making it ideal for aggressive driving and performance applications.

Type-RS Technology:

The Type-RS design utilizes precision RS coil springs between the pressure rings to apply activation pressure in the same direction as initial torque. This innovative approach delivers 50-70% lower initial torque compared to conventional cone plate LSDs, resulting in reduced drive resistance and significantly improved throttle response. The low initial torque setting enables smooth cornering even when the LSD mechanism is not fully activated, while still providing strong locking action when needed.

Key Features:

  • 2-way operation activates on both acceleration and deceleration for maximum control
  • RS spring design ensures consistent performance without clutch plate wear or spring sag
  • Exclusive Oil Through System with radially-cut clutch plate grooves for improved oil circulation and cooling
  • Polished pressure ring contact surfaces for even clutch plate engagement
  • High response with quick transition from non-operational to fully functioning state
  • Proven durability in All Japan Gymkhana Championship competition without overhauls
  • Chromoly steel casing and gears for exceptional strength and longevity

Application:

Designed for rear-wheel drive vehicles and AWD rear axles, the 2-way configuration is recommended for enthusiasts who prefer aggressive driving styles and competitive motorsports applications. The Type-RS is particularly well-suited for low to mid-power vehicles, delivering race-proven performance with street-friendly characteristics.

Fitment: Mazda MX-5 Miata Roadster ND5RC (2016-2018) manual transmission, USDM models only.

I bought an Edge Evolution CS tuner for my 05 Avalanche at a great price, a lot cheaper than any other place I looked. Delivery time was amazing it tooked two days from the time it was processed and it was over the Christmas holiday and it still made it to my front door in less than a week with regular ground shipping. Customer support is awesome and fast at answering any and every question you have and remedying any problem. Great site and great service. Will definitely recommend to others and use again in the future for all my automotive needs. Thanks Autoplicity.
