What is a 2-way limited slip differential and how does it work?

A 2-way LSD engages its locking mechanism during both acceleration and deceleration. This means it helps control wheelspin and improve traction not only when you're on the gas but also when you lift off or brake, leading to a more stable and predictable feel during cornering.

What type of gear oil should I use with this Cusco LSD?

Cusco recommends using their specific LSD gear oils to ensure optimal performance and durability of the clutch plates. Using the wrong type of oil can affect engagement and potentially shorten the lifespan of the differential.

What other parts might I need to replace when installing this differential?

It's a good idea to inspect and potentially replace your rear axle bearings and seals while the differential is being installed. Ensuring these components are in good condition will complement the new LSD and prevent future issues.

About this part

Product Details

Cusco is well-known for making performance drivetrain components, especially for rally and track applications. This MZ-Type 2-Way limited slip differential (LSD) is built for your 2008-2013 Subaru Forester with the EJ25T engine and 5-speed automatic transmission. It's designed to improve traction and handling by controlling how much power goes to each rear wheel, especially during cornering or when one wheel loses grip.

This is a 2-way LSD, meaning it engages both under acceleration and deceleration. This characteristic helps stabilize the rear end during spirited driving, making the car feel more predictable and planted. The MZ-Type uses a cone clutch system, which offers a smooth engagement that's comfortable for daily driving while still providing strong locking force when you need it. The clutch plates are made from durable steel, and the unit is assembled with precision to ensure it works effectively and lasts. This differential is a significant upgrade for anyone looking to enhance their Forester's performance, whether for occasional track days or just more confident driving on winding roads.

When installing a limited slip differential, it's important to use the correct gear oil. Cusco recommends specific LSD oils to ensure proper operation and longevity of the clutch plates. You'll also want to ensure your rear axle bearings and seals are in good condition, as this is a good time to address any wear there. This differential is a substantial upgrade for the Forester's drivetrain, offering a noticeable improvement in how the car puts power down.
