Quaife ATB Helical LSD differential for Porsche G50 is suitable for Porsche models with G50 gearbox. A direct replacement for the standard Porsche differential, the Quaife ATB Helical LSD differential transforms your car's performance.
Unlike a conventional plate-style limited slip differential, the Porsche G50 Quaife ATB Helical LSD differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation.
The Porsche G50 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 Porsche G50 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 Porsche G50 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 Porsche G50 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.

Information
Rear left and right differential carrier bearing.
This tapered roller bearing, also known as a differential carrier bearing, is used in the rear output assemblies of the differential and manual transmission on various classic Porsche models. Engineered as a precise OE replacement, it meets the original Porsche specifications for dimensions, load capacity, and tolerance. The bearing installs directly without modification, restoring proper carrier alignment, support, and smooth drivetrain operation.
Sold individually.

Diagram ref no 8
• Function: This bearing supports and aligns the differential carrier or manual transmission rear output shaft, allowing smooth rotation under load and controlling radial/axial movement of the carrier assembly. It ensures the differential or transmission output runs true, quietly and with minimal friction.
• Position on Car: Usually located in the manual transmission/differential rear housing (for example in the rear of the 911 manual gearbox, or the transaxle/differential carrier area). It may serve as the bearing between the carrier housing and the output shaft or differential ring-gear carrier.
• This part is critical for proper gear meshing, quiet running, bearing life and overall driveline integrity.
With age and use, the bearing can develop wear in its rollers/races, looseness, noise, increased friction, or misalignment. A worn bearing may lead to drivetrain noise, vibration, premature gear or bearing damage, loss of efficiency, or catastrophic failure. The bearing supports the differential carrier output shaft – incorrect bearing performance can result in excessive play, wobble, and stress on neighbouring components.
When to Replace:
• During a differential or transmission rebuild, where the carrier, output shafts or bearings are being replaced — it’s best practice to install new bearings.
• If you detect noise (growl, whine, hum) coming from the rear differential or output area, particularly under load or at higher speed. If there is measurable play / movement in the differential carrier or abnormal backlash in the gearset. If you notice metal debris, “bearing-noise” or vibration emanating from the drivetrain output / differential area.

Replacing this bearing means you restore correct support and alignment, minimise noise, protect the differential and improve durability. This part is critical for proper gear meshing, quiet running, bearing life and overall driveline integrity.
