Cusco HBD 193 A Hybrid Limited Slip Differential Rear 1-Way

The Cusco HBD 193 A Hybrid Limited Slip Differential (LSD) is a high-performance rear differential unit engineered for drivers who demand precise power delivery and enhanced traction. Built with high-tension chrome molybdenum steel housing and gears, this LSD is constructed to handle serious performance driving demands while maintaining excellent street manners.

The Hybrid type LSD combines the best characteristics of Cusco's Type MZ and Type RS designs into a single hybrid configuration, making it especially well-suited for use with automatic transmissions and daily street driving. Activation pressure is applied in the same direction as the initial torque via a coil spring mechanism, enabling a smooth, rapid transition from an unlocked to a fully engaged state—even at low initial torque settings. This results in composed cornering behavior when the LSD is not fully activated, and confident traction transfer when it is.

Key Features:

• Chrome molybdenum steel housing and internal gears for superior strength and durability
• Hybrid LSD design — combines the best qualities of Type MZ and Type RS for street and light competition use
• Large oil windows for increased lubricant flow to clutch plates
• Cusco original groove-cut technology on clutch plates for improved efficiency, stability, and longevity
• Convertible 1-way / 2-way configuration — easily swap between setups to suit your driving needs
• Low initial torque setting enables smooth cornering behavior and quick clutch plate engagement
• Engages immediately when the slightest torque differential is detected between wheels
• Minimal power loss during transfer from engine to drivetrain

The Cusco Hybrid LSD is a premium Japanese-engineered differential upgrade that brings measurable improvements in traction, stability, and power delivery. Manufacturer Part Number: HBD 193 A.
