Cusco LSD 160 K15 Type MZ 1.5-Way Limited Slip Differential

The Cusco Type MZ Limited Slip Differential (LSD 160 K15) is a high-performance clutch-type LSD engineered for drivers who demand precision traction control and confident handling at the limit. Developed using many of the same forged components as the renowned Type RS, the Type MZ has been refined through extensive R&D, track testing, and racing to deliver an exceptional balance of performance and drivability.

The Type MZ sets itself apart through its cone spring–based activation system. Activation pressure opposes the direction of initial torque via a high-pressure cone spring, which causes the LSD to engage as the opposing pressures interact. This design produces the highest initial torque rating of any Cusco LSD model, with the cone spring driving full clutch pack lock-up at a linear rate for predictable, progressive engagement.

An expanded ten-plate clutch pack (five plates per side) increases LSD performance and durability compared to earlier eight-plate designs, providing better response under high-power applications. Cusco's exclusive radially cut clutch plate grooves enable rapid oil movement for improved efficiency and longevity, while the Oil Through System ensures continuous lubrication to critical areas during use.

The pressure ring features dual cam profiles, allowing the LSD to be switched between 1-way & 1.5-way, 1-way & 2-way, or 1.5-way & 2-way configurations without purchasing additional components. This unit is configured as a 1.5-way LSD.

Cusco LSD Way Configurations:

• 1-Way LSD: Activates under acceleration only; reverts to open differential behavior when off-throttle. Ideal for front-wheel drive and AWD front axle applications.
• 1.5-Way LSD (this unit): Activates under acceleration with reduced deceleration locking compared to a 2-way. Recommended for drivers who want strong traction without excessive understeer during corner entry.
• 2-Way LSD: Activates on both acceleration and deceleration. Best suited for rear-wheel drive and AWD rear axle vehicles; preferred by drivers who enjoy aggressive driving and high-angle drifting.

All Cusco LSDs offer adjustable locking characteristics through clutch plate stacking combinations, giving tuners fine-grained control over differential behavior to suit specific driving styles and track conditions.
