Torque Sensing Limited Slip Differential, 84-92 Non Turbo

These very unique torque sensing differential limited slip units are now available for 84 and later RX-7’s. They really are the absolute best design for rear traction under ALL different conditions. It is able to transmit far more torque to the wheel that still has traction than any other type of differential. It uses the friction of the worm gear teeth and the thrust washers for the differential limiting force. In comparison with viscous type, or friction type LSD, it has the following benefits:
1) Large bias ratio torque proportioning
2) Less change of bias ratio over time of car use
3) No special differential oil or LSD additives needed
4) Improved overall traction and improved controllability under acceleration.
5) Virtually no change of torque sensing or traction control through differential temperature range.
*Note- if you have an 86-92 Non-Turbo rear end we KNOW that 86-88 N/A stub axles will work. We also KNOW that 89-92 LSD stub axles will NOT work. If you have 89-92 Non-LSD stub axles, we do NOT know that they will work with this diff. Some measuring will be necessary.
