The OS Giken Super Lock TCD limited-slip differential for Lexus IS‑F (USE20) is a clutch-type LSD intended to replace the factory differential and provide more predictable torque transfer between the drive wheels. It improves traction and stability during hard acceleration or variable-surface driving, giving clearer drive-wheel control for spirited street use or demanding conditions without altering the vehicle's original packaging.
