The Cusco LSD Type-RS 1-Way Rear is a limited slip differential designed for enhanced traction and handling in performance applications. Engineered for Subaru Impreza WRX, Legacy B4, and Forester models from 2008 to 2013, this LSD features a spring-loaded design that absorbs initial torque, providing a smoother power transfer to the wheels. The Type RS offers lower friction and a gentler initial torque response compared to the Type MZ, resulting in more efficient power delivery and reduced power loss. These characteristics translate into improved lap times and better grip during aggressive driving or spirited street use. Constructed with high-quality materials, the differential ensures durability and consistent performance under demanding conditions.
This limited slip differential is a direct upgrade for Subaru models equipped with EJ25T engines within the specified years. It allows users to select two of three settings through a simple overhaul, offering customizable traction control for various driving scenarios. The installation is suitable for track days, spirited driving, or enhanced street performance, providing a significant upgrade over stock differentials. The kit includes the LSD unit itself, designed for bolt-on installation, and is compatible with vehicles that require a rear differential upgrade. Proper fitment and application depend on the specific vehicle configuration, making it ideal for enthusiasts seeking improved handling and reduced lap times.

Overview
Overview
A Cusco Limited Slip Differential offers the absolute best in traction. Cusco LSD allow you to choose 2 of 3 settings with each unit just with a simple overhaul. The Type RS springs absorb the initial torque. Compared to the Type MZ, the Type RS s initial torque comes on more gently. The response of the RS has lower friction and in turn, is transfers power to the ground more efficiently. The Low Initial Torque means Less Power Loss. This equates to lower lap times, even for a mildly tuned vehicle. The low pressure on the clutch plates improves durability and lowers chatter. To top it off, the reduced pressure allows the driver to change the LSD oil less frequently. Steady coil movement is assured by special precision springs set in the pressure plate. These springs are made to be resilient and allow for stable operation. Because these plates do not utilize a cone clutch, they do not stick and allow for increased longevity. The Type RS transfers extreme power without slipping and responds quickly with pedal inputs. This differential is ideal for drag racing or going for drifting. Contact Us with any questions..
Cusco recommends the following setups for the following drivetrains.
- 1 way LSD: Specially suited for front wheel drive cars and AWD front axle cars.Activates under acceleration, and acts as a true LSD when the throttle is off.
- 1.5 way LSD: Activates under acceleration with less under-steer under deceleration than on a 2 way LSD. Recommended for those who want to reduce under-steer.
- 2 way LSD: Recommended on rear wheel drive cars and AWD rear axle cars. Activates on both acceleration and deceleration. Recommended for those who prefer aggressive driving and big angle drifting.
