The USA Standard Gear NP261 & NP263 T-Case Mainshaft is a robust 32-spline component built to withstand the rigors of both demanding off-road excursions and everyday driving. USA Standard Gear is a well-established brand known for its quality aftermarket drivetrain components. They offer a vast selection of parts, ensuring enthusiasts can find what they need for their builds. However, it is always recommended to verify your specific application to ensure compatibility. While USA Standard Gear produces solid parts, it is important to note that the brand is made by Yukon, and some parts may have slight variations in machining compared to OEM components.
