Cusco CT9A EV8 9LSD RSF 1WAY(1&1.5W)

This listing is for the Cusco RSF 1WAY Limited Slip Differential (LSD) with a 9-liter capacity, specifically the CT9A EV8 model. This unit is designed to change how your vehicle's power is distributed between the rear wheels, especially during acceleration and cornering. Unlike an open differential, which sends power to the wheel with the least traction, an LSD actively locks the two rear wheels together to a certain degree, ensuring both wheels receive torque. This particular model is a 1-way LSD, meaning it primarily affects locking under acceleration. It also offers a 1.5-way setting, which provides some locking effect during deceleration as well, offering a more controlled feel during spirited driving or track use.

The RSF series LSDs from Cusco are known for their robust construction and smooth engagement. This unit features a 9-liter fluid capacity, which helps manage heat buildup during demanding use, making it suitable for performance applications where sustained stress on the drivetrain is common. The internal components are precision-machined to ensure reliable operation and longevity. Installing an LSD like this can significantly improve traction off the line and provide a more stable, predictable feel when exiting corners, as it helps prevent wheelspin on the inside tire.

This differential is a significant upgrade for performance-oriented vehicles. It's important to note that installing a limited-slip differential often requires specific gear oil and may necessitate adjustments to your vehicle's setup. Refer to the manufacturer's installation instructions for detailed guidance on proper setup and fluid requirements to ensure optimal performance and durability.
