Cusco LSD 177 E Type MZ 1-Way Limited Slip Differential Rear

The Cusco LSD 177 E is a Type MZ 1-Way (1 & 2 Way) Rear Limited Slip Differential engineered for performance driving. Designed and manufactured in Japan, this LSD is a direct upgrade over an open differential, delivering improved traction, power distribution, and cornering stability for spirited street and track use.

The Type MZ design utilizes a high-pressure cone spring that opposes the direction of initial torque, engaging the clutch pack progressively and at a linear rate. This results in the highest initial torque rating among all Cusco LSD models, making it ideal for drivers who demand immediate, aggressive differential lockup.

Key Features:

• Type MZ Design: Cone spring activation engages full clutch pack lock at a linear rate for maximum initial torque response
• Chromoly Steel Construction: Housing and internal gears are precision-forged from high-tension chrome molybdenum steel for exceptional strength and durability
• Radially Grooved Clutch Discs: Original groove-cut technology enables instant oil movement, improving efficiency and extending clutch plate life
• Polished Pressure Ring Contact Surface: Ensures even, consistent contact with clutch discs for predictable engagement
• Cusco Oil Through System: Large oil windows promote superior oil flow from the casing to pressure rings and clutch plates for efficient lubrication under high-performance use
• Convertible Way Configuration: Pressure ring features dual profiles allowing conversion between 1-way and 2-way settings without purchasing additional components
• Adjustable Locking Characteristics: Responsiveness and lockup behavior can be tuned by changing the plate stacking arrangement
• 1-Way Operation: Activates under acceleration; acts as a true LSD when off-throttle, reducing oversteer during corner entry

The Cusco LSD 177 E is well-suited for rear-wheel-drive performance applications including track days, autocross, and spirited road driving where strong on-throttle lockup and cornering traction are priorities.
