OE Match
90133228501/1
Product Information
This OE Match differential housing lock plate is a replacement locking tab used to secure the differential housing bolts on classic Porsche models. It is designed to match the original-style fitment and locking function, helping keep the differential housing fasteners safely retained.
Sold individually, 8 required for the differential
Fits:
Porsche 911 1965 - 1989
Porsche 914 1970 - 1976
Porsche 924 1976 - 1985
Diagram ref no 8
This lock plate fits on the differential housing assembly, where it is used with the differential housing bolts. It is part of the rear drivetrain / gearbox assembly and helps secure the differential housing fasteners in place.
The lock plate helps prevent the differential housing bolts from loosening under load, vibration, and drivetrain movement. It is an important small fastening component used during differential, gearbox, or rear drivetrain assembly and service.
Functions
• Locks differential housing bolts in position
• Helps prevent bolt loosening under drivetrain load
• Supports secure differential housing assembly
• Helps maintain drivetrain reliability and safety
• Provides an OE Match replacement for the original locking plate
• Suitable for gearbox, differential, and rear axle service work
• Recommended for replacement when the differential housing bolts are removed
Differential lock plates are designed to secure critical fasteners and may lose effectiveness once removed, bent, corroded, or reused. A worn or damaged lock plate may not properly retain the housing bolts, increasing the risk of loosening under load. Replacing the lock plate during differential service helps ensure the assembly is secured correctly and supports long-term drivetrain reliability
When to replace
• The differential housing bolts have been removed
• The gearbox or differential housing is being serviced
• The original lock plate is bent, cracked, corroded, or damaged
• The locking tab no longer holds the bolt securely
• Rear drivetrain repair or rebuild work is being carried out
• The part is missing from the differential housing assembly
• As preventative replacement during transmission or differential reassembly

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.
