Description
Enhance your vehicle’s performance with our state-of-the-art gear oil additive, perfect for both petroleum and synthetic gear oils. Experience a smoother break-in process with temperature reductions of up to 50?F. To eliminate chatter in clutch-type limited slip or posi-traction units, add 1oz incrementally for optimal results.
Crafted from fully-synthetic formulas derived from polyol ester base stocks, our additive ensures outstanding lubrication even under extreme conditions. Benefit from a high viscosity-index (VI) that maintains constant viscosity and film thickness across varying temperatures. Ester base stocks and friction modifiers enhance slipperiness, lowering operating temperatures by minimizing sliding friction in hypoid gears.
Our superior shear stability and reduced oxidation, when compared to other synthetics and conventional gear oils, guarantee unmatched performance. Exceeding API GL-5 specifications, our product is engineered to provide maximum protection, enhance differential efficiency, and contribute to better mileage, longer drain intervals, and reduced wear.
Designed to meet the performance requirements of GM 1052358, Ford M2C118-A, 19B546-MA, Chrysler 4318060, and most imports, our additive is a trusted choice. Follow our recommended dosage of 4% for preventing limited slip chatter in broken-in units (typical one 4 oz. bottle) or 4 to 8% for the break-in of new differentials.
Say goodbye to excess wheel spin and reduced traction?opt for Red Line 75W90NS with the Red Line Limited-Slip Differential Friction-Modifier/Break-In Additive until chatter disappears. This product significantly reduces friction during differential break-in, preventing rapid wear caused by high temperatures.
Our additive is versatile, compatible with both petroleum and synthetic gear oils. For non-limited-slip racing differentials and quick-change units using Red Line ShockProof Gear Oils, we recommend an additional 3 to 6% of Red Line Limited-Slip Differential Friction-Modifier/Break-In Additive.
In a convenient 118ml (4oz) size, this additive is your key to optimal vehicle performance. Trust Red Line for a breakthrough in differential care and improvement.
