FAQ Q1: Does the upgraded differential cover increase the differential oil capacity?A1: Yes, most upgraded Dana Super 60 differential covers increase oil capacity by 0.5 to 1 quart. This additional capacity enhances cooling and extends the lifespan of the gears. Q2: Is the Dana Super 60 differential cover compatible with OEM differential oil?A2: Yes, it is fully compatible with OEM-recommended differential oil. However, for better heat resistance and lubrication, high-performance synthetic gear oil is recommended. Q3: Does the differential cover come with a magnetic drain plug?A3: Yes, most high-performance differential covers include a magnetic drain plug. It captures metal debris, reducing internal wear and prolonging the differential's lifespan. Q4: What is the impact of an upgraded differential cover on high-temperature driving?A4: Enhanced features like cooling fins and increased oil capacity help significantly reduce operating temperatures during heavy-duty or high-temperature driving conditions. Q5: Does the weight of the differential cover affect vehicle performance?A5: No, upgraded covers are typically made of lightweight aluminum alloy. This material provides excellent cooling performance without negatively affecting vehicle...
