Compatible with all 75W90 gear oils, it fine-tunes limited-slip differentials while preventing corrosion, ensuring enhanced traction and drivetrain longevity without any assembly. ## Description 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.For perfect traction use Red Line 75W90NS and add the Red Line Limited-Slip Differential Friction-Modifier / Break-In Additive until the chatter disappears.Satisfies performance requirements of GM 1052358 Ford M2C118-A 19B546-MA Chrysler 4318060 and most imports.Recommended Dosage: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-incan 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. Compatible with both petroleum and synthetic gear oils Reduces break-in temps as much as 50 F Add 1oz at a time to clutch-type limited slip or posi-traction units to eliminate chatter Fully-synthetic formulas created from polyol ester base stocks offer excellent lubrication under extreme conditions High viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature change Ester base stocks and friction modifiers provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears Superior shear stability and reduced oxidation compared to o ## Features - Replaces the limited-slip additives - Can be added to any gear oil - Ideal to tune a limited-slip unit ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000CPCBGE | | Best Sellers Rank | #545,049 in Car & Motorbike ( See Top 100 in Car & Motorbike ) #1,280 in Engine Oils for Cars | | Brand Name | Red Line | | Compatible Material | petroleum or synthetic gear oils | | Container Type | Bottle | | Customer Reviews | 4.7 4.7 out of 5 stars (307) | | Global Trade Identification Number | 00083522803014 | | Item Form | Liquid | | Liquid Volume | 4 Fluid Ounces | | Manufacturer | Red Line | | Material Type | Synthetic | | Model Number | 80301 | | Number of Items | 1 | | Part Number | 80301 | | Recommended Uses For Product | Limited-slip differentials, Differential break-in | | SAE J300 Viscosity Grade | 75W-90 | | Specific Uses For Product | Prevent Corrosion | | UPC | 083522803014 | | Unit Count | 4 Fluid Ounces | | Viscosity | 75W90 | ## Product Details - **Brand:** Red Line - **Liquid Volume:** 4 Fluid Ounces - **Material:** Synthetic - **Package Information:** Bottle - **Recommended Uses For Product:** Limited-slip differentials, Differential break-in ## Images ![80301 Limited Slip Friction Modifier - 4 oz. - Image 1](https://m.media-amazon.com/images/I/71auZeP6jKL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Would the 95 Isuzu 4x4 front differential benefit from this additive? I know the rear limited slip diff does!** A: No, unless it's a limited slip after market and specifies such. On the rear positive, too much would cause slippage between the plates. Just ad enough to stop the clanging. Too much would lesson the Limited slip . **Q: Can this be used in redlline dct fluid that is used in a manual tranmission with lsd?** A: It was purchased for my son. I didn't use it. My son is a car mechanic, so I think it is a good product. **Q: Would this help a 95 Isuzu front 4x4 differential? ...that chatters around corners on pavement?** A: Check your u-joints but if there ok. Let me know if it worked. Differential Gear oil is supposed to be replaced on a regular Preventative maintenance Schedule. I don’t know what the mileage is on your car is but it couldn’t hurt “unless your vehicle is not a LSD Diff.” Thanks! **Q: do I need that for my 99 chevy express 1500 V8 with amsoil 80W90 together?** A: My chevy Silverado 2500HD ran better after adding a 4oz. can of Redline with the rear gear oil. There is also an additive for the transfer case GM put in during a service. I would double check before putting that in the transfer case. Keep on reading, you'll find the answer.
