Quaife ATB Helical LSD differential is suitable for Nissan R200 280-300Z / 200SX models and fits both S13 & S14 with equal length drive flanges. 29 sline direct replacement for the standard Nissan open differential, the Quaife ATB Helical LSD differential transforms your car’s performance.

Unlike a conventional plate-style limited slip differential, the Nissan R200 280-300Z / 200SX Quaife ATB Helical LSD differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation.

The Nissan R200 280-300Z / 200SX Quaife ATB Helical LSD differential never locks harshly with a set pre-load of wheel slip across the driven axle, like a conventional LSD. Rather, the Nissan R200 280-300Z / 200SX Quaife ATB Helical LSD differential automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree, and never locks.
