Achieve maximum traction and transform your car's handling with the Tran-X (by Quaife) Limited Slip Differential. As the proven choice for our own A-series race cars, this plate-style LSD offers unparalleled adjustability, allowing you to fine-tune torque transfer for everything from aggressive circuit racing to spirited road use.

Product Specs

• Type: Multi-plate Limited Slip Differential (Salisbury style)
• Compatibility: MG Midget and Austin-Healey Sprite (A-series axles)
• Adjustment: Multiple ramp angle and preload configurations
• Components: Dual ramp blocks with precision planet carrier pins
• Part Number: TDX2K

Why Choose the Tran-X LSD?

• Proven Competition Pedigree: Extensively track-tested in our own fleet to ensure reliability and performance under extreme racing conditions.
• Customisable Locking Action: Available with various ramp angles (e.g., 35° for aggressive locking or 55° for smoother transition) to suit your driving style.
• Adjustable Preload: The internal plate friction can be tuned to dictate how rapidly the diff locks, allowing you to balance the car's turn-in and exit stability.
• Dynamic Torque Transfer: Unlike standard differentials, the Tran-X actively pushes torque to the wheel with the most grip, essential for shaving seconds off lap times.
• Precision Engineering: Manufactured by Quaife to the highest standards, ensuring a robust unit that translates driver input directly into forward motion

Installation Tip: Setting up a plate-style LSD is a specialist task. The combination of ramp angles and preload will drastically alter the car's balance; we recommend a professional setup to ensure the unit is shimmed correctly for your specific application.

[As used in all of our race cars with A-series axles. Many setup options available for both race and road use.]

[The Tran-X (by Quaife) LSD is a multiple plate limited slip differential like the old Salisbury units. It features two ramp blocks sandwiching two planet carrier pins which sit in the radius between the leading and trailing ramp angle. As torque is applied to the differential’s input, the pins ride up their respective leading ramps, pushing the blocks apart and increasing the transfer of torque across the axle.]

[The angle of this ramp determines how quickly this transfer occurs within the LSD. An angle of 35 degrees allows the blocks to be pushed apart more readily than a 55 degree setting, resulting in a more aggressive differential locking action. Plus, the preload setting dictates the contact friction between the plates themselves. The higher the preload, the more rapidly friction increases between the plates, creating a more aggressive locking action. Combined with the ramp angles, the preload allows subtle adjustments to the torque transfer characteristics allowing users to alter the dynamic balance of their car.]
