Spicer SPL70-4X U-Joint Kit SPL70WJ Series (ISR)

The Spicer SPL70-4X U-Joint Kit SPL70WJ Series has received a mix of feedback from customers, primarily highlighting both its quality and concerns regarding fitment accuracy. Users who have successfully installed the kit on compatible models, particularly on Ford F-550s and certain GM medium-duty trucks, praise its sturdy Construction and reliable performance. Many reviewers commend the design and manufacturing quality, noting that the product is "well made in the USA" and seems to surpass the longevity and reliability of some comparable aftermarket options like Moog and Precision. However, there are notable issues regarding fitment accuracy that potential buyers should be aware of. Some customers experienced significant frustration when they found that the U-joint did not fit their vehicles, specifically when ordered for the 2015 F-250 with a Dana 60 axle. The inConsistencies between the product listing and the actual fit have caused unnecessary returns and dissatisfaction. This discrepancy indicates that while the product itself may be of excellent quality, users should verify vehicle compatibility before purchasing to avoid similar issues. In summary, the Spicer SPL70-4X U-Joint Kit is a well-regarded component among those who can utilize it correctly, but the misleading fitment guidance is a serious concern that may dampen the overall customer experience for some. **
