LSD 185 B15 Limited-Slip Differential
Product Overview
The LSD 185 B15 Limited-Slip Differential is designed to enhance your vehicle's performance by ensuring that power is effectively transferred to the wheels, regardless of road conditions. Unlike standard open differentials, which allow for wheel slippage, the LSD system actively engages to provide better traction and stability, making it an essential upgrade for motorsport enthusiasts and everyday drivers alike.
Key Features
- 1.5 Way Locking Mechanism: This system allows for both 1 and 1.5-way locking, giving you flexibility in how your differential responds during acceleration and deceleration.
- C-Size Configuration: Specifically designed for a direct replacement of the OE Viscous LSD, ensuring compatibility and ease of installation.
- Precision Engineering: Crafted with a focus on fine-tuning, this differential can be adjusted to match your driving style and the demands of various motorsport stages.
Benefits of Upgrading to LSD 185 B15
Upgrading to the LSD 185 B15 can significantly improve your vehicle’s handling and performance. By limiting wheel slippage, this differential allows for better acceleration out of corners and improved stability on uneven surfaces. Whether you're navigating tight turns on a track or driving on slick roads, the LSD ensures that power is distributed evenly, enhancing grip and control.
How It Compares to Factory Components
The factory components are generally designed for everyday driving, which may not provide the traction needed in high-performance situations. The LSD 185 B15 improves upon these factory components by offering a more responsive locking mechanism that engages when necessary, ensuring that you maintain control under various driving conditions. This upgrade is particularly beneficial for drivers who push their vehicles to the limit, providing a competitive edge in both racing and spirited driving scenarios.
