Ask the Experts about this Redline Trailer Suspension
- What is the Difference Between U-Bolts 176500 and SP01-080
- At first glance, I was puzzled as well. But upon closer inspection, I have an answer for you. The difference is that Suspension U-bolt, # 176500, is just one bolt.
SP01-080 is the same shape, size, and used for the same application (5.2K, 6K and 7K Axles) but it comes with two bolts.
And part number 175666 that you reference is 1/2 inch wider, 1-3/4 inches longer, and is used on 8K Axles.
