Quaife ATB Helical LSD differential for Nissan 300ZX is suitable for Non-Turbo models as well as the R200 found in the S13 and S14 240SX. A direct replacement for the standard Nissan differential, the Quaife ATB Helical LSD differential transforms your car's performance.

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

The 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 300ZX 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.

The Quaife ATB Helical LSD differential has many benefits over a standard open differential, including maximising traction and minimizing wheelspin, eliminating torque steer and snatching in front wheel drive cars compared to conventional LSD units, and a maintenance-free design which retains the standard oil lubrication.

The Quaife ATB Helical LSD differential is proven in circuit and drag racing, rallying and road use, and is produced from Corus steel billets, and is CAD designed and CNC machined, then inspected to ISO 9001 standards.

The QDF7L will also install in most short nose R200 differentials including Nissan 300ZX (Z32), Nissan 240SX (S13, S14), Infiniti J30, and JDM Nissan 180SX, Silvia, and R32, R33, R34 Skylines. Check spline count of diff axle stubs before ordering – the QDF7L only accepts 29 spline diff stub axle flanges.
