Video Transcript for Redline Trailer Suspension 175211 Review

Today we'll be reviewing part number 175211. This is Redline's Replacement U-Bolt with the two nuts that are going to be included for two inch wide square trailer axles. This is used with a u-bolt plate to secure the axle to the leaf springs which are mounted to the trailer frame. It's going to attach with the u-bolt plate which is sold separately, and an additional u-bolt with the same dimensions as this one, also going to be sold separately. This will fit square two inch wide trailer axles. It's going to include the u-bolt along with the two nuts.

The bolt diameter, if we take a look at that real quick, it's going to give us a measurement of nine-sixteenths of an inch. The length that we have from the bottom of the cross member to the end of the bolt is going to measure five and three quarters of an inch. The width that we have between the two u-bolt studs is going to measure two inches. That's going to do it for our review of part number 175211. This is Redline's Replacement U-Bolt with the included nuts.

Had 12 leaf springs that broke, got 6 leaf from Etrailer, had to replace the U bolts for the thinner stack. These U bolts are thicker (stronger) than the originals I had.

My boat trailer broke and I needed to replace the entire suspension system. I called around to local businesses and would have to wait several weeks for them to order the parts. I began searching online and found etrailer.com. I looked up the parts I needed and all of them were in stock. The shipping was free and the parts were received sooner than I could have ordered them from a local retailer. Also, the price from etrailer.com was cheaper than what I would have had to pay locally. I am very pleased and will continue to use etrailer.com for all of my trailer part needs. I plan on telling everyone I see about my experience and suggest they use etrailer.com as well. Thank for helping me fix my trailer. I will post pictures when the job is finished.

  • Recommended Leaf Springs for Vintage Trailer
    The 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 27" Long # SP-210275 will work with your vintage trailer. It looks from the photo like you would also need the Replacement U-Bolt with Nuts for 2" Wide, Square Trailer Axles - 9/16" Diameter # 175211 and the U-Bolt Plate - 2" Wide, Square Trailer Axle - 1-3/4" Wide Spring - 9/16" Bolts # TRTP200175. You will need to reuse your shackle straps, but you can use the Wet Equalizer Bolt with Locknut and Grease Zerk for Double-Eye Springs...
