Why Mopar Limited Slip Differential Additive Is Necessary
From my experience, using Mopar Limited Slip Differential Additive is essential for keeping my vehicle’s differential running smoothly. Limited slip differentials rely on friction to distribute power between wheels, and without the right additive, that friction can become uneven or excessive. This additive helps to ensure the clutch plates inside the differential engage properly, preventing chatter and noise that I’ve noticed when the wrong or no additive is used.
I’ve also found that Mopar’s formula protects the internal components from wear and corrosion, extending the life of my differential. It improves lubrication under high pressure and extreme conditions, which is vital for maintaining performance and avoiding costly repairs. In short, adding this specific additive gives me peace of mind that my limited slip differential is operating efficiently and quietly, especially during spirited driving or tough road conditions.
My Buying Guides on Mopar Limited Slip Differential Additive

Here’s what I learned along the way that helped me pick the best Mopar Limited Slip Differential Additive for my needs.
Understanding What a Limited Slip Differential Additive Does
I found that the LSD additive is specially formulated to reduce chatter and noise in limited slip differentials while providing proper lubrication.

How to Use Mopar Limited Slip Differential Additive

Following the instructions carefully helped me maintain my differential’s longevity and smooth operation.
What I Wish I Knew Before Buying
