Cusco LSD 431 L15 Type RS 1.5-Way Limited Slip Differential

The Cusco LSD 431 L15 is a high-performance Type RS 1.5-Way Limited Slip Differential (LSD) designed for drivers who demand precise torque distribution and improved traction under both acceleration and light deceleration conditions. Built to Cusco's exacting Japanese engineering standards, this LSD is a direct-fit replacement unit engineered for enhanced grip and consistent performance on the street and track.

Key Features:

• 1.5-Way Operation: Provides full locking behavior under acceleration and partial locking under deceleration, offering a balanced blend of street drivability and aggressive performance
• Type RS Design: Cusco's race-inspired helical or clutch-type internals deliver smooth, predictable torque transfer without the chatter associated with lesser units
• High-Quality Construction: Manufactured with precision-machined components and durable clutch plate materials for long service life under demanding conditions
• Direct OEM Replacement: Designed to install into the factory differential housing without modification, using stock ring and pinion gears
• Improved Cornering Traction: Reduces inside wheel spin during corner exit, allowing more power to be applied earlier for faster acceleration out of turns
• Street and Track Capable: The 1.5-way setting makes this LSD appropriate for both daily driving and performance use, unlike fully locked 2-way units

The Cusco LSD 431 L15 is part of Cusco's renowned LSD lineup, a brand trusted by enthusiasts and professional motorsport teams across Japan and worldwide. This unit is ideal for drivers seeking a meaningful upgrade over the factory open differential without sacrificing everyday usability.
