Genuine Dana Spicer 707144X Dana 60 Trac-Lok Carrier Case

If you're rebuilding a Dana 60 the right way, this is where it starts.

The Dana Spicer 707144X is a genuine OEM Trac-Lok limited-slip differential carrier case designed for Dana 60 rear axles with 4.10 and numerically lower gear ratios. This is an empty case kit, making it ideal for replacing a damaged or worn factory unit while reusing or upgrading internal components.

This isn’t offshore aftermarket. This is real Dana/Spicer—the same quality used in heavy-duty factory applications. When you're dealing with real horsepower, towing loads, or hard launches, that difference matters.
