REAR DIFFERENTIAL AIR VENT BREATHER, 86-11 RX7, RX8
Rear Differential Air Vent Breather 86-11 RX7 and RX8
L.S.D. GEAR OIL ADDITIVE
If you get a “chatter” from the rear axle when starting from a stop, and turning at the same time, you need to add this additive to your rear end oil. This is due to the clutches in the differential locking and un-locking. The Limited Slip Additive assists with the applying and releasing of the clutch plates. One container/part number needed per rear end oil change.
For clutch type limited slips – all OEM’s through 1988. The later ones are either viscous or Torsen type and do not require additive.
