What is the main benefit of a 1-way limited-slip differential?

A 1-way LSD primarily locks under acceleration. This helps to pull the car through corners more effectively, reducing understeer and providing a more predictable feel when you are on the throttle. It's designed to enhance traction and control during spirited driving.

What is the 'Nissan side shaft swap' mentioned for this differential?

This Cusco front LSD is designed to fit the 2001-2007 Subaru Impreza WRX, but it requires a specific modification for installation. You will need to swap in a side shaft from a Nissan vehicle to ensure proper fitment and function with your Impreza's transmission.

Does this differential come with all the necessary hardware for installation?

This product includes the Cusco Type-MZ 1-way front limited-slip differential. However, it does not include the required Nissan side shaft or any other installation hardware. It is recommended to consult the manufacturer's installation guide or a professional mechanic for a complete list of required parts and tools.

About this part

Product Details

If you're looking to significantly improve your 2001-2007 Subaru Impreza WRX's traction and cornering ability, especially for track or spirited driving, a limited-slip differential (LSD) is a key upgrade. This Cusco Type-MZ 1-way front LSD is designed to help put power down more effectively, reducing wheelspin and enhancing your car's ability to rotate through turns. It's a popular choice for drivers who want more control and a more engaging driving experience.

The Type-MZ series from Cusco is known for its smooth engagement and durability. This 1-way unit primarily locks under acceleration, which helps to pull the car through corners and provides a more predictable feel when you're on the throttle. It also offers a degree of 1.5-way action, meaning it provides some locking effect during deceleration as well, further aiding stability. The internal components are well-built to handle the stresses of performance driving, and the unit is designed to work with the factory differential case, though it requires a Nissan side shaft swap for proper installation. This swap is a common modification when upgrading the front differential on these WRX models.

Installing a front LSD like this Cusco unit is a significant modification that can change how your car handles. It's important to ensure you have the correct supporting parts for the Nissan side shaft swap, as this is a necessary step for this differential to fit your 2001-2007 Impreza WRX. When properly installed, you'll notice improved grip out of corners and a more planted feel, especially when accelerating hard.
