Limited Slip Differential Friction Modifier & Break-In Additive is a fully-synthetic formula created from polyol ester base stocks that provides more slipperiness, lowers operating temps, & offers great lubrication in extreme conditions.
RED LINE Limited-Slip Friction Modifier & Break-In Additive is a full-synthetic formula created from polyol ester base stocks, that offers excellent lubrication under extreme conditions. Limited-slip or Positraction units use plates or clutches to provide the proper amount of lock-up to the differential. Slippery lubricants are required to prevent chatter, but too much slipperiness causes excess wheel spin, reducing traction. For perfect traction, use Red Line 75W90NS and add the Red Line Limited-Slip Differential Friction-Modifier / Break-In Additive until the chatter disappears. This product exceeds API GL-5 specifications.
