Video Transcript for Redline Trailer Suspension 115983 Review

Today we will be reviewing part number 115983. This is Redline's ubolt plate from 1 1/2" squared trailer axles with 1 3/4" wide springs. This is used with ubolts to secure the axle to the lead springs which are mounted to the trailer frame. It's going to attach with 2 1/2" diameter square ubolts. They are going to be sold separately. The 1/2" diameter is important because you want to make sure that the ubolt goes through the 1/2" diameter hole.

The 4 holes along the corners are going to be the same in diameter so you will need to get some ubolts. I'm going to recommend part number Sp01-120. Those ubolts are going to come with the nuts to secure them on the other side and it's going to fit this mounting plate perfectly. This does fit square trailer axles that are 1 1/2" wide. It will work with 1 3/4" wide lead springs.The overall dimensions of the mounting plate is going to give us a measurement of 5 1/4" x 3 1/2". That's going to do it for today's review of part number 115983.

This is Redline's ubolt plate from 1 1/2" squared trailer axles with 1 3/4" wide springs. .

I purchased this plate to upgrade the suspension on my trailer. I would get a a lot of trailer sway when I was towing my jet ski trailer. I bought the trailer used and never really looked at the springs. Unfortunately for me, There was nothing but one U bolt strapped diagonally across the spring. I'm no suspension expert but I knew this could NOT be safe. I did extensive research on trailer suspension. It was difficult to find parts for a 11/2 inch square axle. It was until I came across etrailer webpage. They had everything I required to upgrade and make my trailer safe to operate on the road. It was actually criminal what the person did to attach the original spring. I am greatful nothing ever happened while towing. Now with the new parts installed, I feel a lot better and my trailer does not sway anymore.

I will definitely purchase my trailer needs from etrailer from now on. The pictures and videos make finding what I needed so much easier. The complete transaction from order to delivery was extremely efficient and the customer service is absolutely outstanding!



by:

Much heavier than what I replaced on my little trailer. Thank you for your fast shipping and follow-up call.



by:

Good quality product would purchase aga in



by:

Efficient and skilled service.....a rarity today.



by:

The most difficult part was tightening the nuts to the point that the head of the shackle bolt was flush against the shackles and hangers. Afterward, I loosened the nuts a little. But, I don't know how much to loosen them.

.I ordered 4 square u-bolts and 2 plates as part of replacing the axel on a 1977 small boat trailer. Needed longer u-bolts than I fond any place else, but trailer had ones that could work. Ideally would have preferred stainless or at least galvanized for use in salt water, but at least could get trailer back on the road. 1 of the 4 u-bolts I ordered was narrower than the rest, had to be forced on at risk of damaging the threads. The center hole in the plate was too small to fit over the top bolt head on the leaf spring; so had to resort to under slung install - which was not the original trailer setup.

I will have our customer service team reach out to you. I would recommend using a corrosion resistant spray with the u bolts and plate. When using in salt water then rinsing off the u bolts and plates with freshwater will help to length the life of the parts.



by:

Well I can't believe it's really been a year since I purchased all the parts from Etrailer to rebuild my jon boat trailer. I bought this tilt trailer on craigslist and well let's just say needed some MAJOR TLC. From the roller brackets, fenders, tires/wheels, hitch coupler, winch, etc.. All the parts have held up extremely well and I am VERY happy with not only the quality of the parts but the customer service as well. This is my "GOTO" place to buy parts for all 3 of my trailers!!



by:

This part was very hard to find any where, but as always, etrailer came thru. The part went on an old Gamefisher trailer and it was a perfect fit. Now I'll be able to complete my project and get the trailer back on the road. The price was very good and finding the part on etrailer was very easy.

Its been a year and the parts are great. No problems what so ever. Thanks etrailer for having hard to find parts and great ones too.



by:

Everything worked great as expected
>Thanks



by:

I purchased the 3000# axle springs and all mounting hardware to replace the old ones on my 1963 travel trailer. My trailer no longer leans to the left and goes down the road better than new. I should have done it many year ago. I received my package on time and installation was easy and fit perfect. Thanks Bridget



by:

The above product I purchased from etrailer was perfectly described and exactly what I was looking for. it was said to be for a 1-1/2" Square Axle and 1-3/4" wide Springs which was exactly what I was looking for. I haven't installed them yet, but have dry fitted them if you will and should work out perfectly Thank You very much!



by:

100% impressed with etrailer. My customer rep, Diana, was very courteous, knowledgeable, and friendly. I placed my order on Monday and was told that my shipment would arrive on Thursday. About ten minutes later, I received an email stating that my order had shipped! I just received another email that my package has been delivered - a day early. I was able to track the package from the etrailer website. I just want to say thank you for the unexpected, exceptional service from everyone at etrailer. I look forward to placing more orders in the near future. Thanks again



by:

All of the springs and hangers were quality material. These parts were a lot heavy duty than I was expecting, and I was glad of that. I now have a light weight but strong boat trailer.



by:

fits great I wish there was a galvanized version, trailer sits by saltwater bay. I coated them with cold galvanizing spray paint see how long it lasts.



by:

Quality product, the only issue was the square U bolts didn’t line up exactly and I had to spread them open fit the hole pattern. But no big deal. Finding parts for replace the previous one was no easy task but you guys had everything. Thank you. On shipping however it seem as if the package only took 3 days to get to Vegas but took another 4 days to go 30 miles to me. I know it’s not your fault but thought I’d mention it anyways. I should have the parts installed soon and will update with photos of the installation.



by:

Worked great. I used them to construct a kayak rack onto my trailer.



by:

Exactly what I needed, very strong piece, I do wish it had been galvanized, but still great. Delivered fast with no problems, etrailer.com as always is great.



by:

Great product but UPS did a terrible job on the delivery. MO to CA in three days and the product was at the UPS distribution center for four days (10 miles from my home) before being delivered.



by:

Heavy duty and a good replacement for my 40 year old rotting u-bolt plates.



by:

I was pleasantly surprised at the quality of the U-bolts and accurate measurements of the U-bolt plates and bolts. This made the installation a breeze.

Thanks



by:

Great product, price and shipping. I would recommend to anyone. Used these after flipping an axle from inside springs to under. Worked great.



by:

Good product. Thanks for the fast ship ping!



by:

Great products the u bolts were just what I needed and I could have not ask for better service products I will always be a customer for any need that y'all can for fill and the videos really helped knowing what I needed and if it was going to fit my application thanks again for being a great company



by:

This plate changed my life. My trailer is no longer popping off it's axle, at every inopportune moment.
Now, thanks to this wondrous device, I have a way of attaching the wheels, to the rest of the frame.
Why hasn't anyone ever thought of this before?
Thank you, and keep up the good work.



by:

Heavy duty compared to the original U-bolt plate that came off this old trailer. U-Bolts slid right in without the use of a hammer. Check out my review about the 1 1/2 U bolts though.
