Why Mopar Limited Slip Differential Additive Is Necessary
From my experience, using Mopar Limited Slip Differential (LSD) additive is essential for keeping my vehicle’s differential running smoothly and quietly. The limited slip differential relies on friction to transfer power between the wheels, and without the right additive, the clutches inside can become noisy or even wear out prematurely. I’ve noticed that adding this specific additive helps reduce chatter and ensures the differential operates as it was designed to.
Another reason I trust Mopar’s LSD additive is that it’s formulated to work perfectly with my vehicle’s differential components. Regular gear oil alone doesn’t provide the special friction characteristics needed for limited slip differentials. By using the additive, I’m protecting my differential from excessive wear and tear, which saves me from costly repairs down the road. Overall, it’s a small step that makes a big difference in maintaining my car’s performance and longevity.
My Buying Guides on Mopar Limited Slip Differential Additive

- Viscosity and Performance: The additive needs to maintain the right viscosity to provide optimal friction modification without causing excess wear or chatter.
- Quantity and Packaging: I opted for a size that matches my differential’s capacity to avoid waste. Also, a well-sealed bottle is important to preserve the additive’s quality.
- OEM Approval: I preferred Mopar additives that are OEM-approved or recommended for my vehicle to avoid any warranty issues.
How to Use Mopar Limited Slip Differential Additive
From my experience, it’s crucial to follow the manufacturer’s instructions carefully. Usually, the additive is mixed with the differential fluid at a specified ratio. Proper mixing ensures the limited slip mechanism works smoothly without noise or slipping.
