Looking For U-Bolt To Fit 4" Axle
Updated 10/27/2025 | Published 03/12/2025
Question:
Do you have a 9/16 x 4 x 7 1/4 round U bolt to fit a 4 axle? If so, what is part number and how much are they? If you dont have them, do you know where I can get them. I have a torsion/air suspension axle rated at around 7K lbs. I believe it is a Dexter, but I am not sure.

Hello Michael, thanks for reaching out. We do offer one U-bolt for a 4" round axle, and that is part # 11-64. This U-bolt measures 8-1/8" long x 4" wide inside. The bolt is 5/8" diameter. We do not have anything 9/16", but if you have a 4" round axle it should still work for you. See the dimensions I included below. You can also see our current pricing below. If you think this will work, you can order directly from us.
Leave a reply below. If you have any other questions or comments I will get back to you.
