Cusco LSD 040 PEFB Limited Slip Differential

The Cusco LSD 040 PEFB is a performance clutch-type limited slip differential engineered and manufactured in Japan to Cusco's exacting motorsport standards. Designed to replace a factory open or viscous differential, this LSD delivers consistent torque distribution to both driven wheels, improving traction, stability, and driver confidence under hard acceleration and through corners.

Key Features:

• Clutch-Type LSD Design: Eliminates uneven power distribution by transferring torque from the wheel with less grip to the wheel with more, maximizing traction during aggressive driving
• Oil Through System: Cusco's exclusive oil-through design ensures pressurized flow of differential gear oil to all internal components for improved efficiency and longevity
• Radially Cut Clutch Plate Grooves: Enables instant oil movement between plates, improving both efficiency and durability
• Polished Pressure Ring Contact Surface: Provides even, flat contact with clutch plates for consistent and predictable LSD engagement
• Adjustable Locking Characteristics: Cam angle settings and plate stack configuration can be tuned to adjust responsiveness and locking behavior without purchasing additional parts
• Competition Proven: Cusco LSDs have been validated in the All Japan Gymkhana Championship, completing full seasons without requiring overhaul
• 100% Manufactured and Tested in Japan: Built with chromoly steel casing and gears for superior durability and precision fitment

The Cusco LSD 040 PEFB is intended for performance and motorsport applications. As with all Cusco drivetrain components, it is designed for use in off-highway competition environments and sold without warranty. Always use Cusco LSD-specific differential fluid for optimal performance and service life.
