Cusco LSD RS 1 Way(1&2) Rear GDA/Impreza/BR9/BM9/BP5/SH5/SHB

Cusco is well-known for making performance drivetrain components, and this RS 1-Way Limited Slip Differential (LSD) is a prime example of their expertise. If you're looking to get the most out of your 2001-2007 Subaru Impreza on the track or during spirited driving, this differential is designed to put power down more effectively.

This is a 1-way LSD, meaning it primarily locks during acceleration. This design helps to reduce wheel spin when you're getting on the throttle, allowing you to put more power down through the rear wheels. The RS series uses a unique clutch plate design that offers a smooth engagement during normal driving, but locks up firmly when you need it. This balance means you get improved traction when accelerating hard without sacrificing too much comfort during everyday driving. The differential itself is built with robust materials to handle the stresses of performance driving.

Installing a limited slip differential is a significant upgrade for your drivetrain. It's a job that requires careful attention to detail and often specialized tools, so it's best handled by a qualified mechanic. Once installed, you should notice a substantial difference in how your Impreza handles acceleration out of corners and off the line.
