1998 Jeep Wrangler Trac-Lok
My 1998 Jeep Wrangler Sahara 4.0L has a Trac-Lok limited slip rear differential. The service manual requires that 4oz of limited slip lubricant be added to the 75W-90 gear oil. This Trans-X® Posi-Trac® Limited Slip Gear Oil Additive meets the specifications for my Jeep. The pointed cap made it easy to inject into the differential through a 3-foot plastic tube.

Caution - check your owner's manual
Advance should update their system a bit. The 2010-2014 F150 with electronic lockers do NOT require friction modifier of any amount. That wasn't noted when shopping for my maintenance fluids.
