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

A limited-slip differential (LSD) improves traction by sending more torque to the wheel that has better grip. This helps prevent wheelspin during acceleration, especially when cornering, leading to better control and performance.

What makes the Cusco RS1 series unique?

The RS1 series from Cusco utilizes a clutch-type design with a unique ramp plate system. This allows for adjustable torque bias, giving you the ability to fine-tune how the differential locks up based on your driving needs.

What is involved in installing this differential?

Installation requires replacing the factory differential with this unit. It's a complex job that typically involves removing the rear axle and potentially modifying or replacing other drivetrain components. Professional installation is recommended if you are not experienced with this type of work.

About this part

Product Details

If you're looking to get the most out of your 2001-2007 Subaru Impreza on the track or during spirited driving, a limited-slip differential (LSD) is a serious upgrade. This Cusco RS1 Rear LSD is designed to help put power down more effectively, especially when you're accelerating out of corners. It works by sending more torque to the wheel that has more grip, preventing wheelspin and improving your overall traction and control.

The RS1 series from Cusco is a clutch-type LSD that offers a good balance between performance and daily drivability. It uses a unique ramp plate system that allows for adjustable torque bias, meaning you can fine-tune how aggressively the differential locks up. This particular unit is built for the rear axle of your Impreza, and it's a well-built component designed to handle the stresses of performance driving. Installation involves replacing your factory open or viscous differential with this unit, which requires some mechanical know-how and specific tools, so it's often best handled by a professional or experienced DIYer.

When you're pushing your car hard, having a differential that can keep up is crucial. This Cusco LSD is a popular choice for Subaru enthusiasts looking for improved performance and a more engaging driving experience. It's a solid option for anyone serious about maximizing their Impreza's handling capabilities.
