LSD 986 K15/K2 Limited-Slip Differential
The LSD 986 K15/K2 is a top-tier Limited-Slip Differential (LSD) designed to enhance your vehicle's performance on the road or track. Unlike standard open differentials that allow for wheel slippage, this LSD ensures that power is effectively transferred to the ground, providing superior traction under various conditions.
Why Choose LSD 986 K15/K2?
This differential is engineered for motorsport applications where every bit of power matters. When driving on challenging surfaces or during aggressive maneuvers, the LSD minimizes the 'free-wheeling' effect of slipping wheels, allowing for a controlled locking effect. This means that both driving wheels receive the necessary power, improving acceleration and handling.
Key Features
- Classic Cone Plate Spring Actuation: This system provides a reliable and responsive locking mechanism.
- Opposing Lock Vector: The initial lock cone spring works against the driveline actuation force for optimal performance.
- Progressive and Linear Actuation: Enjoy a shallower rate of actuation, ensuring smooth transitions during driving.
- Durability: Built to withstand the rigors of high-powered racing while maintaining maximum simplicity.
- Tuning Options: Choose from 2 pressure plate cam positions to customize your locking preferences.
Fitment
- Scion FR-S
- Subaru BRZ
Benefits of Upgrading to LSD 986 K15/K2
Upgrading to the LSD 986 K15/K2 offers significant improvements over factory components. The enhanced locking mechanism provides better traction during acceleration, cornering, and on slippery surfaces. This not only boosts your vehicle's performance but also improves overall driving confidence, making every drive more enjoyable.
Customer Experience
Many drivers have shared their satisfaction with the LSD 986 K15/K2. One customer noted that after installing the LSD, they experienced a noticeable difference in their car's handling during tight turns. They appreciated how the differential allowed for smoother power delivery without the harshness of a fully locked system.
