The Quaife ATB Helical LSD differential improves your vehicle's performance drivability.  Unlike a conventional plate-style limited slip differential, this helical LSD differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation.

The 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.

• Smooth engagement
  
• Quiet Operation
• No special oil needed
• Better and more predictable turn-in
  

Q: Should I install a Clutch-Type or Torsen (Helical) Differential?

A: The reason to choose a clutch type differential over a torsen (Quaife) type differential is if you frequently get a drive wheel up in the air, such as in rally racing or when bouncing over large curb sections on road courses.

• To install you will need: Bearing and Seal Kit
• If installing in an E153 transmission originally equipped with the factory LSD:Ring Gear Bolt Kit
• If installing in an E153 transmission originally equipped with the factory LSD and you need a functional vehicle speed sensor you’ll need an MR2 non-LSD VSS gear (not needed for most cars with ABS- if your old transmission didn’t have one, you don’t need it. MK2 MR2 DOES need it.
