Does this OS Giken LSD come with all necessary hardware for installation?

This product is the differential unit itself. Installation typically requires reusing some factory hardware and may need additional specialized components or fluids as per the manufacturer's installation instructions.

What type of fluid should I use with the OS Giken Super Lock LSD?

Product Details

This is the OS Giken Super Lock Limited Slip Differential (LSD) specifically for the front of your 2007-2011 Subaru Impreza WRX STI (GRB chassis). If you're looking to significantly improve traction and handling, especially during spirited driving or track use, an LSD is a critical component. This unit replaces your factory open differential, allowing both front wheels to receive power more evenly, even when one wheel loses grip. This means better acceleration out of corners and more stable handling under load.

OS Giken is well-known for its high-performance drivetrain components, and their Super Lock LSD is a popular choice for enthusiasts seeking a robust and effective upgrade. It utilizes a unique multi-plate design that offers a high degree of locking action, which can be adjusted to suit your driving style and track conditions. The internal components are made from durable materials designed to withstand the stresses of performance driving. Installation involves replacing the entire front differential assembly, so it's a job that requires mechanical expertise and specific tools, often best handled by a professional mechanic.

When installing this LSD, it's important to use the correct differential fluid recommended by OS Giken to ensure proper break-in and long-term performance. This unit is designed as a direct replacement for the factory front differential, meaning it fits within the stock differential housing. Upgrading to a limited-slip differential like this one can fundamentally change how your Impreza puts power down, offering a more connected and capable driving experience.
