Cusco LSD 317 F Type RS 1-Way Front Limited Slip Differential

The Cusco LSD 317 F is a Type RS 1-way front limited slip differential designed for performance-oriented street applications. This mechanical clutch-type LSD uses an innovative coil spring preload system that delivers progressive locking characteristics and exceptional throttle sensitivity, making it ideal for front-wheel drive vehicles seeking improved traction and handling.

Key Features:

• Coil Spring Design: Unlike traditional cone spring LSDs, the Type RS uses multiple coil springs between pressure rings to generate initial torque, providing gentler engagement and more consistent performance over time
• 1-Way Configuration: Specially suited for front-wheel drive cars and AWD front axles, activating under acceleration while allowing free differential action during deceleration to reduce understeer
• High-Strength Construction: Features high-tensile forged chromoly side and pinion gears, case, and components for reliability under high-performance applications
• Oil Through System: Proprietary case design maximizes oil circulation and cooling for enhanced durability and consistent operation
• Radially Cut Clutch Plates: Exclusive groove pattern enables instant oil movement, improving efficiency and extending service life
• Dual Ramp Angle Pressure Rings: Two-position adjustable cam allows tuning of lock-up characteristics without purchasing additional components
• Precision Polished Surfaces: Pressure ring contact surfaces are polished for even, flat contact with clutch plates ensuring smooth operation
• Lower Initial Torque: Enables smooth turning even when LSD mechanism is not activated, reducing clutch wear and extending rebuild intervals compared to high-preload designs

The Type RS LSD is perfect for low to mid-power vehicles, offering highly reactive performance with low resistance for better clutch response, pedal feel, and reduced clunking noise. The coil spring design maintains constant pressure against clutch plates, resulting in minimal loss of initial torque over time and substantially less frequent rebuild intervals compared to traditional cone spring differentials.

Position: Front
Transmission Type: Manual (MT)
LSD Type: 1-Way Mechanical Clutch Type
Model: Type RS

Designed for drivers seeking improved corner exit traction and mid-corner control on high-performance street vehicles. The 1-way design is specifically recommended for those who experience understeer and want better front-end grip during acceleration without the negative handling characteristics of a 2-way LSD at the front axle.
