Once again they had what I needed as the local hardware store did not. Quick delivery.



by:

Arrived quickly and fit perfectly. Could not find this size u-bolt anywhere, but found it on etrailer. Very pleased.



by:

Met my expectations and I'm totally satisfied with the product and it's quality.



by:

Finally found the right size parts with you. They definitely we're what we were looking for and they arrived on Tuesday when I wasnt expecting until Friday.



by:

E-Trailer was the only place that had the 1 3/4 inner width size.
The price was overall $1.50-$2.00 cheaper than comparable products at other stores and NONE of them had the correct size.
Perfect as an OEM replacement and quality product.
Great email updates on order status.
2 day shipping arrived as ordered. Thank you for using UPS!

My trailer was already prepped upside down with the stretched rusty old u-bolts off. The new u-bolts installed in no time. I have safe secure trailer axle with, ATV loaded and am ready for the Holiday Weekend!



by:

Great place to deal with. They were the only ones that had these square U-bolts in this size. Shipping turn around was terrific. I believe it was only 4 days of waiting, one was a Sunday, another was due to the carrier only delivers to my rural location once a week. Part arrived yesterday, I finished out my trailer kit, from another company, that was missing this part, today. Thank you, I'll be a returning customer.



by:

These worked really well as a much stronger, and better made replacement for the bolts that came with my haul master trailer kit.



by:

Used to mount a plastic storage bin to my PWC trailer and working great.



by:

Received them yesterday. Harbor Freight had a $399 trailer on sale for $279 and the last one they had was missing the U-bolts to assemble it and they sold it to me for $180! Now I can put it together and enjoy my savings!
