Review on 🔴 Red Line Limited Slip Friction Modifier - 4 oz. (Part # 80301) by Robert Elder

I love, trust and use Redline oil in my vehicles. When my limited slip differential started to rattle, which happened every time after a fluid change with Redline 75w90 GL5 gear oil, which is suitable for LS differentials, I usually add two extra bottles of this limited slip friction modifier to eliminate vibration . Most other brands of limited slip friction modifiers come in tubes that fit into the differential's fill hole. This Redline comes in a bulky bottle that's guaranteed to spill half onto the garage floor. Do yourself a favor and buy another brand's Limit Slip Friction Modifier that comes in a squeezable tube.
