Quaife ATB Helical LSD Rear Differential Fits Nissan R200 29 Spline (Check Vehicle Compatiblity)

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. 

The QDF7L will install in all long nose R200 differentials with 10mm or 12mm ring gear bolts found or retrofitted in Datsun 240Z, 260Z, 280Z, 280ZX, Nissan 300ZX (Z31), Nissan Silvia (S12). 

Vehicle Compatibility: 

- Nissan S30 240Z / 260Z / 280Z
- Nissan S130 280ZX
- Nissan Z31 300ZX
- Nissan S12 Silvia (Open Centre)

The QDF7L will also install in most short nose R200 differentials including Nissan 300ZX (Z32),  Infiniti J30, Infiniti Q45 (30 spline), and JDM Nissan S13, S14, S15 200SX, 180SX, Silvia and R32, R33, R34 Skyline's.

Note:
Check the spline count of diff axle stubs before ordering – the QDF7L will only accept 29 spline diff stub axle flanges.

If your R200 diff does not have 29 spline diff stub axle flanges you must source 29 spline stub axle flanges from another R200 diff that match the CV axle bolt pattern of (5 or 6) of your current stub axle.

If your R200 is using larger than 12mm ring gear bolts a crown wheel change or modifications would be required.
