Cusco LSD — Type-RS / Type-MZ
The Cusco LSD — two initial-torque designs, three operating modes, and an operating mode that can be changed at overhaul without new parts.
Brand: Cusco
Product Name: Cusco LSD
Product Code: lsd
Designs: Type-RS (low initial torque, high responsiveness, road-legal) and Type-MZ (coned plate with groove-machined clutch plates for improved oil flow and response)
Operating Modes: 1Way, 1.5Way, 2Way (selectable at build and changeable at overhaul without new parts)
Compliance: Road-legal (vehicle-inspection compliant, per the Cusco catalogue)
Note: This is the legacy-catalogue listing on Cusco's net shop, aimed at vehicles ten years old and up. Confirm the exact model number for your chassis, drivetrain and gearbox before ordering.
The Cusco LSD is one of the more configurable diffs on the Japanese market. Type-RS gives you a road-friendly low initial torque with real responsiveness, and Type-MZ steps up to a coned-plate pack with grooved clutch plates that pass more oil for a cleaner, more consistent lock. Either can be built 1Way, 1.5Way or 2Way, and Cusco set it up so an overhaul lets you change the mode without buying a new unit — the same diff can move from track work back to street use as the car's job changes.
Features:
- Two Design Choices: Type-RS for low initial torque and responsiveness, Type-MZ for the grooved coned-plate pack.
- 1Way / 1.5Way / 2Way: Selectable at build for accelerate-only, hybrid or full drift-style lock.
- Mode-Switchable at Overhaul: Change operating mode without a new unit.
- Road-Legal: Passes Japanese vehicle inspection as sold.
- Legacy-Vehicle Focus: Aimed at cars ten years and older in the Cusco net-shop listing.
For owners of older performance cars putting the drivetrain back on track terms, and for drift and time-attack builds picking a lock they can rebuild rather than replace.
