Cusco LSD Type RS 1.5-Way(B-Size) Lexus 09-19 IS250/350 / 10-19 GS350/450h 100% Lock

This Cusco Type RS 1.5-way limited slip differential (LSD) is designed for specific Lexus models, including the 2009-2019 IS250/350 and the 2010-2019 GS350/450h. You'll receive the differential unit itself, ready for installation. This LSD is engineered to provide a 100% lock under acceleration and deceleration, significantly improving traction and handling, especially during spirited driving or when exiting corners.

The Type RS is a well-built unit that utilizes a unique cam mechanism to adjust the lock-up rate. In a 1.5-way configuration, it offers strong locking under acceleration for maximum grip and a controlled amount of locking under deceleration to help stabilize the vehicle. This design is particularly beneficial for rear-wheel-drive vehicles, helping to put power down more effectively and reduce wheel spin. The 'B-Size' designation refers to the specific spline count and housing dimensions required for the target Lexus vehicles, ensuring a proper fit when installed by a qualified technician.

Installing an LSD like this can fundamentally change how your car puts power down, offering a more connected feel and improved performance. It's a popular upgrade for drivers looking to enhance their vehicle's handling characteristics. Because this is a significant drivetrain modification, it's recommended to consult with a professional mechanic for installation to ensure all specifications are met and the differential is properly set up with the correct gear oil.
