The OS Giken Super Lock limited-slip differential is a performance-focused LSD that improves traction by transferring torque between driven wheels, helping control wheelspin and sharpening cornering response for manual-transmission cars. Its progressive locking action suits spirited street use and track driving where consistent traction matters. Fits manual Chevrolet Corvette models (1986–1996) and Dodge Viper models (1992–2002).
