Red Line Limited Slip Friction Modifier is the ideal additive for reducing chatter and friction-based temperatures during differential break-in. Limited-slip differentials use plates or clutches to provide the required amount of lock-up designed into the differential. While slippery lubricants are required to prevent chatter, too much slipperiness can cause excessive wheel spin and reduced traction.
- Compatible with both petroleum and synthetic gear oils
- Reduces break-in temps as much as 50°F
- Add 1oz at a time to clutch-type limited-slip or posi-traction units to eliminate chatter
Use 4% for prevention of limited-slip chatter in broken-in units (typically one  4 oz. bottle) or 4-8% for the break-in of new differentials.
Red Line Limited-Slip Friction-Modifier additive will significantly reduce the friction during differential break-in of differentials. High temperatures encountered in break-in can destroy the hardening of the gear teeth causing rapid wear of the softened gears. This Red Line additive can reduce the break-in temperatures by as much as 50°F, improving break-in conditions.
For perfect traction, use Red Line 75W90NS and add small amounts of this Red Line Limited-Slip Friction-Modifier until the chatter disappears.NOTE:
Red Line Gear Oils already contain this additive (except the NS version).
In non limited-slip racing differentials and quick-change units using the Red Line ShockProof Gear Oils, an additional 3-6% of Red Line Limited-Slip Differential Friction Modifier is recommended.
