Cusco PRO-ADJ LSD RS GC8 GDB GRB GVB Rear

This is the Cusco PRO-ADJ RS Rear Limited Slip Differential (LSD) for specific Subaru models including the GC8, GDB, GRB, and GVB chassis. A limited slip differential is a crucial component in your drivetrain that helps manage power distribution between your rear wheels, especially during cornering or when traction is uneven. Unlike an open differential, which sends all power to the wheel with the least resistance, an LSD allows for controlled power transfer to both wheels, improving traction and handling performance. This PRO-ADJ RS model from Cusco is designed for drivers who want precise control over their differential's locking characteristics.

The PRO-ADJ RS series features an advanced clutch-disc design that allows for on-the-fly adjustment of its locking force. This means you can fine-tune how aggressively the differential locks based on driving conditions, track setup, or personal preference without needing to remove the differential itself. It utilizes a combination of a 1.5-way and 2-way locking mechanism, offering strong initial lock-up on acceleration and a controlled lock on deceleration. The internal components are well-made to handle the stresses of performance driving, ensuring consistent performance when you need it most. Installation involves removing the factory differential and installing this unit, which typically requires specialized tools and knowledge of drivetrain components.

When installing a performance differential like this, it's important to ensure all related drivetrain components are in good condition. You'll also need to consider the appropriate gear oil for its break-in period and subsequent use, as specified by Cusco. This differential is a significant upgrade for those looking to maximize the handling potential of their Subaru, providing improved grip and responsiveness during spirited driving and track use.
