What is a 1-way limited-slip differential?

A 1-way limited-slip differential primarily locks when you accelerate, helping to send power to both rear wheels. When you release the throttle, it allows the wheels to rotate more freely, which can make the car feel more neutral when turning.

What is the main benefit of installing this LSD in my Forester?

This LSD will improve traction and stability, especially when cornering or if one rear wheel loses grip. It helps ensure that power is delivered more evenly to both wheels, leading to a more confident driving experience.

Does this differential come with all the necessary installation hardware?

This listing is for the Cusco MZ-Type 1-Way rear differential unit itself. It is recommended to refer to the manufacturer's installation instructions for a complete list of any additional hardware or fluids that may be required for proper installation.

About this part

Product Details

Cusco is well-known for making performance drivetrain components, especially for rally and track applications. This MZ-Type 1-Way limited-slip differential (LSD) is built for the rear of your 2008-2013 Subaru Forester equipped with the EJ25T engine and the 5-speed automatic transmission. A limited-slip differential helps put power down more evenly to both rear wheels, especially during cornering or when one wheel might lose traction. This means improved grip and a more stable feel when you're pushing your Forester.

The MZ-Type is a clutch-type LSD that offers a 1-way engagement. This means it primarily locks under acceleration, providing a predictable feel when you're on the throttle. When you let off the gas, it disengages, allowing for more neutral handling characteristics. This design is often favored for its balance between traction enhancement and everyday drivability. The unit is constructed with durable materials designed to handle the stresses of spirited driving and track use, ensuring it holds up over time.

This differential is designed as a direct replacement for your factory unit, though professional installation is recommended due to the complexity of differential work. It's important to ensure you have the correct fluid for limited-slip differentials when performing the installation, as using the wrong type can affect performance and longevity. This LSD is a significant upgrade for any Forester owner looking to improve their vehicle's handling and traction capabilities.
