Video Transcript for Redline Trailer Suspension 175643-Z Review

Speaker 1: Today we're gonna take a look at the replacement zinc-plated 3/8in diameter U-Bolt with the nuts for 1 3/4in round trailer axles. This replacement U-Bolt will access part of your trailer suspension system. It's designed to be used with another U-Bolt and a U-Bolt plate. Both items we do sell separately on our website to secure one side of your axle to a leaf spring which is mounted to your trailer's frame. This round bolt will fit 1 3/4in round trailer axles. It is a zinc-plated steel construction, which is heavy duty, corrosion resistant.

It's ideal for use on boat or snowmobile trailers. This part will include the one U-Bolt and the two nuts. A few specs on this. Again, the application is 1 3/4in diameter round axles so if we measure the inner width that goes over the axle, there's your 1 3/4in. Total length, which is measured from the inside to the end of the bolt, see it's 4 1/4in.

The thread portion measures 1 3/4in and, again, the bolt diameter is 3/8in. The nut size that fits on it is 3/8in by 24 threads per inch and the head size on this nut that the socket fits on is 9/16in. That should do it for the review on the replacement zinc-plated 3/8in diameter U-Bolt with nuts for 1 3/4in round trailer axles.

Speedy shipping and a perfect fit, these U-bolts were just the item I needed to put my new eTrailer 5-leaf springs on my tilt-bed utility trailer, upgrading from skinny, light duty 3-leaf springs. In fact, I returned home from work to find that my 15 year old daughter had grabbed them from the mailbox and installed them for me 301923

Ask the Experts about this Redline Trailer Leaf Spring Suspension

  • Hole Dimensions in U-Bolt Plates 117535-G and TRTP175173
    The four holes in the U-Bolt Plate parts # 117535-G and # TRTP175173 are sized to accept 3/8-inch u-bolts like # 175643-Z. I went to our warehouse and measured these plates' thickness and hole diameters and found them to be 1/4-inch and 0.4-inches respectively. Note that since these items are die-formed there can be slight variances between samples.
