S30 240/260/280Z, S130 280ZX, Z31 300ZX & S12 Silvia Quaife ATB Helical LSD Differential R200

A direct replacement for the standard Nissan open differential, the Quaife ATB Helical LSD differential transforms your car’s performance.

The Nissan QDF7L Quaife ATB Helical LSD differential transforms your car’s performance. Unlike a conventional plate-style limited slip differential, the Nissan R200 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 QDF7L Quaife ATB Limited Slip Differential LSD is designed to prevent the complete loss of drive that occurs with a conventional differential when one wheel slips. While requiring some torque in the slipping wheel, the Quaife unit is progressive in action but never locks, controlled power is transmitted to all the driving wheels

Best suited to high powered front, all and rear wheel drive systems, The Nissan Quaife ATB differential is ideal for autocross, lapping and road racing where it outperforms other LSD systems including clutch-type LSD. With low heat generation (no diff cooler required) and unlocking under throttle lift and deceleration, the Quaife LSD provides a predictable, stable power transfer in cornering, braking and transitions while preserving the reliability of the differential unit, lap after lap.

Installation is identical to the normal differential with bearing pre-loads and pinion mesh being restored to the original manufacturer’s settings. Servicing of the unit is simple as all gear pinions are free fitting and normal final drive lubrication oils are retained. Due to the internal design of the Quaife ATB differential, all driving wheels must be elevated when servicing brakes, wheels etc.

The Quaife Rear 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 Rear 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.
