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. Its large oil windows boost oil flow, and Cusco's unique groove - cut technology enhances clutch - plate efficiency, ensuring stability and long life. The 1.5 - way Type RS uses coil springs between pressure rings to generate initial torque. It fully engages during acceleration and partially under deceleration. Coil springs, instead of cone plates, offer faster, smoother engagement and greater durability. This LSD can be converted to a 2 - way type. It's fully customizable with different clutch - pack orders and spring - tension presets, letting you set it according to your preference. You can also change this unit to a 2 - way by rotating the center spline. It activates strongly during acceleration and less so during deceleration, making it suitable for all motorsports. With top - notch acceleration performance and a lighter lock - up on deceleration, it's ideal for road racers. Despite the milder deceleration lock - up, it can be used in aggressive motorsports like drifting or low - gear auto - crossing. FWD vehicles get better braking stability with this LSD.

Using the Cusco RS 1.5 Way Rear Limited Slip Differential is straightforward. Just install it in your Subaru WRX (2002 - 2014) or Legacy GT (2005 - 2009) with a 5 - speed manual transmission as per the included instructions. When driving, you'll notice it engages well during acceleration, giving you more power and control. During deceleration, it has a lighter lock - up. Remember, you can customize it by adjusting the clutch - pack order and spring tension to fit your driving style. If you want to convert it to a 2 - way differential, rotate the center spline. As for maintenance, regularly check the oil level and quality. Replace the oil as recommended in your vehicle's manual to keep the gears and clutch plates in good shape. Also, inspect for any signs of wear or damage, like unusual noises or vibrations. If you notice anything wrong, have it checked by a professional mechanic.
