Why Mopar Limited Slip Differential Additive Is Necessary
From my experience, using Mopar Limited Slip Differential (LSD) additive is essential to keep my vehicle’s differential running smoothly. The limited slip differential has clutch plates that need proper lubrication to function correctly. Without the right additive, these clutches can wear out faster due to increased friction and heat, which can lead to noisy operation and even premature failure.
I’ve noticed that the Mopar LSD additive helps reduce chatter and noise when the differential is working hard, especially during turns or on slippery surfaces. It creates a special friction modifier that ensures the clutches engage smoothly and quietly. This not only improves my driving comfort but also protects the internal components from excessive wear.
Overall, adding Mopar Limited Slip Differential additive is a simple step I take to maintain my vehicle’s performance and prolong the life of the differential. It’s a small investment that helps me avoid costly repairs down the road, making it a necessary part of my regular maintenance routine.

Why I Choose Mopar Limited Slip Differential Additive
I’ve found that Mopar’s additive is specifically formulated for limited slip differentials, which means it’s designed to reduce chatter and wear in these systems.
