Red Line Limited Slip Friction Modifier

Red Line Limited-Slip Friction Modifier

Red Line Limited Slip Friction Modifier and Break In Additive is compatible with both petroleum and synthetic gear oils.

Add 1 fluid oz (about 30ml) at a time to a clutch type limited slip diff or positraction unit to eliminate chatter

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.

Sold in 118 ml / 4 fl oz bottles

Use 4% for prevention of limited slip chatter in broken-in units (typical one 4 oz. bottle) or 4 to 8% for the break-in of new differentials.

Red Line Limited-Slip Differential Friction-Modifier / Break-In Additive will significantly reduce the friction during 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 additive can reduce the break-in temperatures by as much as 50°F, improving break-in conditions.

Compatible with petroleum or synthetic gear oils. Red Line Gear Oils already contain this additive (except the NS).

In non limited-slip racing differentials and quick-change units using the Red Line ShockProof Gear Oils an additional 3 to 6% Red Line Limited-Slip Differential Friction-Modifier / Break-In Additive is recommended.

Red Line makes gear oils for specific applications, not one type to satisfy most fairly well.

Their GL-5 differential lubricants contain friction modifiers and reducers to lubricate limited-slip clutches properly and reduce friction of the ring and pinion. Non Slip or "NS" gear oils are designed for transmission use where synchronizers need the proper friction to synchronize gear shifts.

The “MT” series is designed for synchronized gearshift applications where lower sulfur levels are desired.

All formulas have a high viscosity index to deliver relatively constant viscosity with temperature change. Synthetic polyol ester base stocks deliver excellent lubrication under extreme conditions, superior shear and oxidation stability, as well as natural multigrade properties, eliminating the need for unstable thickeners.

Red Line gear and transmission oils are recommended for passenger car, commercial and racing applications.
