What is a 1.5-way limited slip differential?

A 1.5-way LSD engages fully when you accelerate, helping to put power down evenly. During deceleration, it engages partially, offering a balance between locking and allowing the wheels to rotate at different speeds for more predictable handling.

What is the main benefit of installing this LSD?

The primary benefit is improved traction and handling. By locking the rear wheels together, it helps prevent wheelspin and ensures more consistent power delivery, especially when cornering or driving on surfaces with varying grip.

What else might I need to install this differential?

Installation typically requires specialized tools and knowledge. You will also need to purchase the correct differential fluid, as LSDs require specific formulations to function properly and maintain durability. Always refer to the manufacturer's installation guide.

About this part

Product Details

Cusco is well-known for making performance drivetrain components, especially for rally and track applications. This Type-MZ 1.5-way limited slip differential (LSD) is designed to improve traction and handling for your 1992-1996 Subaru GC8 or 1997-1998 Subaru SF Forester. It works by mechanically locking the rear wheels together under acceleration and deceleration, which helps put power down more evenly, especially when cornering or on uneven surfaces.

The Type-MZ is a clutch-type LSD, meaning it uses a series of clutch plates to create the locking effect. This particular model is a 1.5-way unit, which means it engages fully during acceleration but only partially during deceleration. This offers a good balance between aggressive locking for corner exit and predictable handling during braking. The internal design uses precision-machined components for smooth operation and durability. This unit is designed to fit directly into the rear differential housing, replacing your factory open or limited-slip differential.

Installing a limited slip differential is a significant upgrade for any Subaru enthusiast looking to improve their car's performance. It's important to note that installing an LSD often requires specialized tools and knowledge, and it's recommended to consult the manufacturer's installation instructions or a qualified mechanic. You will also need to ensure you have the correct differential fluid, as LSDs often require specific formulations to function correctly and avoid premature wear.
