Description

The Spec-F LSD features special flat friction clutch plates for a milder initial engagement (acceleration ON/OFF), ideal for RWD circuit use and minimizing power loss in low-HP vehicles. It retains Type RS specs, offering smoother cornering due to Flat Friction Plates (FFP), making it versatile for Sunday racers and street use. The RS Model uses a coil spring for smoother, quicker initial clutch plate engagement with low initial torque, allowing smooth turns before full LSD activation. RS Springs provide constant pressure, minimizing initial torque loss. The pressure ring has dual profiles for switching between 1 way, 1.5 way, and 2 way without extra components. It activates under acceleration with less understeer during deceleration than a 2-way LSD. All Cusco LSDs offer adjustable responsiveness and locking characteristics via plate combination and stacking. Exclusive Cusco clutch plate grooves are radially cut for instant oil movement, improving efficiency and durability. The pressure ring contact surface is polished for even contact. The exclusive Cusco Oil Through System enhances oil circulation with Cusco LSD Oil.
