Cusco RS Rear Limited Slip Differential 1.5 Way (R160) Subaru WRX 2002-2014 / Legacy GT 2005-2009 5spd MT

Part #: LSD 183 L15. The Cusco LSD is crafted for serious competition, featuring a high - tension chrome molybdenum steel housing and gears. It has large oil windows for better oil flow and Cusco's unique groove - cut technology on the clutch plates, enhancing efficiency, stability, and longevity. The 1.5 - way Type RS uses coil springs between the pressure rings to generate initial torque. It fully engages during acceleration and partially under deceleration. Coil springs offer faster, smoother engagement and greater durability compared to cone plates. This LSD can even be converted into a 2 - way one. It's highly customizable with different clutch pack orders and spring tension presets, letting you set it up according to your exact preferences. You can change this unit to a 2 - way by rotating the center spline for engagement during both acceleration and deceleration. It activates well during acceleration and less so during deceleration, making it suitable for all motorsports. Its optimized acceleration performance and lighter deceleration lock - up are great for traditional road racers. Even though it has a lighter deceleration lock - up, it can be used in aggressive motorsports like drifting, low - gear auto - crossing, and gymkhana. It also improves stability in FWD vehicles during braking.

Using your Cusco RS Rear 1.5 Way Limited Slip Differential is straightforward. Just install it as per the vehicle's manual instructions for your Subaru WRX or Legacy GT. When driving, you'll notice it engages well during acceleration, giving you better traction. During deceleration, it has a lighter lock - up, which is normal for this type. For those who want to convert it to a 2 - way differential, simply rotate the center spline as described in the product details. As for maintenance, regularly check the oil level and quality. The large oil windows make it easier to ensure proper oil flow. If you notice any strange noises or a decrease in performance, it's a good idea to have it inspected. And since it's customizable, you can adjust the clutch pack order and spring tension presets whenever you want to fine - tune it according to your driving style.
