The Cusco Type MZ Limited Slip Differential (LSD 429 K15) is a high-performance rear differential upgrade designed for the Mazda MX-5 Miata ND5RC chassis. This 1.5-way LSD features Cusco's advanced cone spring design that delivers the highest initial torque rating of any Cusco LSD model, providing superior traction and control for both street and track driving.

Key Features:

• 1.5-Way Design: Activates under acceleration with reduced under-steer during deceleration, ideal for drivers seeking better vehicle control and corner entry stability
• High Initial Torque: Cone spring pressure system engages the full clutch pack at a linear rate for immediate response and predictable power delivery
• Adjustable Configuration: Customize responsiveness and locking characteristics by adjusting the combination and stacking order of clutch plates
• Oil Through System: Exclusive Cusco design enhances oil circulation to critical areas when used with Cusco LSD oil, improving efficiency and durability
• Radial Clutch Grooves: Precision-cut grooves enable instant oil movement between plates for improved efficiency and extended service life
• Polished Pressure Rings: Contact surfaces are precision-polished for even, flat engagement with clutch plates

The Type MZ is engineered for drivers who demand maximum performance and prefer the aggressive engagement characteristics suited to track driving and spirited street use. The high cone spring pressure provides strong initial bite and excellent traction out of corners, making it particularly effective for reducing under-steer in tight turns. Professional installation and use of Cusco LSD oil is recommended for optimal performance.
