Perfect replacement

I needed to make a small adjustment to my trailer's winch stansion. But, had to cut the original U-bolts off.

I went online and ordered the exact replacements.

Roger M. (Dana Point, US)

Needed a little more thread or 5-3/4" long. The next size down was too short so I had to go with longer and then ran out to thread and had to washer up to fit.

Pacific Trailers was AWESOME!!!

Very happy with my purchase from Pacific Trailers. Fast reasonable shipping with tracking for exactly what was needed to help rebuild my unknown branded boat trailer. I'm using all stainless steel fasteners including these u-bolts from Pacific Trailers. Fantastic direct replacements for my rusty originals. Thank you !!!

Five star Excellent product at a good price. Fit perfectly.

Pedro C. (Danville, US)

Salt water finally got to my original U Bolts for the winch post (20 years old). I order 3 and happy I did because I had a second fail. Easy to put on and were the correct items I needed.

Stainless Steel Hardware

I am a guide on the Texas Coast and I deal the constant problem of saltwater corrosion. I have a aluminum trailer but the hardware is not.
I am upgrading my trailer with stainless steel fasteners to make it as maintenance free as possible. Thanks to Pacific Trailers

Looks clean. Had 3 in steel that didn't hold winch post and went for 4 in stainless. Hope it works!
