Bushing kit performed like new. Easy to rebuild.

Guy D.


Great product. Made hook up a lot easier.


This kit works, not too hard to install. How to on youtube.


Great selection on older towing accessories most always in stock.. thanks


These parts fit my Sterling Tow Bar perfectly. They were easy to change and now the tow bar works like new. Oh, and shipping was amazingly fast. Thank you.


Great product to repair those hard to move tow bar arms. Woud be excellent if it included the split sleeve bearing for the alminium housing or at least recommend it be ordered at the same time.
Included is a pic of one of my bushing, what's left of the bushing. The other arm was worst.


Before I ordered the 2 rebuild kits for and older model Sterling All Terrain Roadmaster towbar I did a lot of investigation. Called etrailer and was reassured the rebuild kits were compatible for my age of towbar. I then called Roadmaster and was told the same thing. I ordered them from etrailer as I’ve always been pleased with their service and timely delivery.
To my surprise when i recieved the product and installed the bushing on the internal arms I found the arms would no longer fit into the tubes. I tried sanding them a bit but then thought why am I doing this they were supposed to fit.
Called etrailer and they said because I altered the bushings there would be no refund. They helped by calls Roadmaster and guess what. The rebuild kits are made for the later issue steely towbar and the installation requires sanding of the round bushings in order for them to fit. Hmm,
Never told that and the instructions didn’t say anything about sanding but as it turns out I did what was supposed to have been done.
As there would now be no refund because the parts were altered I carried on with sanding the bushings. Not an easy thing on a round donut.

Roadmaster agreed to send me 3 more so I can start over. Thank you Roadmaster

The kits were also missing 1 white 3/4 in nylon washer and the 2 c-clips for the small pins that hold the springs. Also being sent by Roadmaster.

According to Roadmaster, theres been some running design changes over the years that will affect the fit of the inner bushings. On some models, the fit will indeed need to be adjusted by removing a small amount of material on the bushing.


It only took a few minutes to install the bushing after talking about a bushing that I realized was hidden with the technician. The bars slide with very little effort and I am thankful to everyone.
Next spring we will be trading cars so I will need to order new tow bar equipment. Hope there is no back log.

Still working great as long as one keeps the bars clean and lubed with a silicone spray


Note that this product only fits certain Sterling tow bars, best to disassemble your tow bar and examine the inner arm type before purchase.

This bushing kit is intended for the Roadmaster Sterling non all Terrain models that have a serial number that is lower than 27671. You will need to spread the 2 arms apart on the tow bar and then look for the sticker where the two arms come together. That is where you should find the serial number.


Exact replacement. Just what I needed to rebuild my Roadmaster Sterling tow bar and convert to a Blue Ox spec. baseplate.


I just completed our Florida trip using my Roadmaster tow bar rebuilt with your parts. Connecting and disconnecting has never been easier. I bought the tow bar used and if I had known what a difference rebuilding would make, I would have done it years ago.


Product was exactly what I needed. Shipping was extremely fast. My older Sterling tow bar is like brand new. Thanks

Keith R.


Excellent, switching from Blue ox was the best thing we ever did


Fast cheap shipping combined with the factory Roadmaster parts. Great company to deal with.

Harold R.


I love the improvement in the towbar.


There are several options for baseplate and associated items to set autos up for towing but I used the expertise of the etrailer reps that recommended the 'correct' items to make it happen. I recommend etrailer often.


I received the parts in just a few days. Packaged well including very good instructions. I received regular communication of the shipment time, transit updates and an email the package had actually been delivered to my shipping address. Prior to ordering the parts, I had several questions on my application, the parts, and the installation. All of my questions we answered completely and timely. Every step from initial contact to completion of the repairs was a great customer experience. These guys are awesome!


The bushing kit I ordered to rebuild my Roadmaster tow bars worked like new now.


I have an older Roadmaster Sterling towbar that the inner arms were sticking. Ordered the bushing kit. Received promptly. Installed last night and works like it was new. Thanks etrailer!!


We bought all of these parts to rebuild a used Sterling tow bar we bought. They all worked and fit perfectly. It actually made hitch feel and work like a new one for a lot less money.


Installation instructions were included and made installation very easy.
Parts in kit were exactly as listed on web site.
I have purchased from several times, all with great product, pricing, and delivery.


Very much liked the quick way of preparing my order for shipment and providing ship data.retrived the package the next day. wasn't any problem for me.
The parts did the job for me. Thanks Paul


My Sterling tow bar rods needed to be pounded in with a mallet before I replaced the bushings, now it works perfectly again I just wish I would have changed them sooner. Just what I needed, shipped fast, great customer service.


Quality Product, Excellent customer service, fast shipping!!


The instructions are good just make sure you clean all parts before installing new kit! Boy do they slide in and out with ease now better than when it was new!!


Parts to refresh sterling tow bar. Works great. etrailer is a good company to work with.


Parts were delivered on time, exactly what I wanted. The assembly instructions were very helpful. My tow bar assembly works like new, I especially liked the shipping tracking.
I'm happy. You can't ask for anything more!


All parts came in as advertised and were super easy to install. My Sterling Tow Bar feels like it's new again. Thank-you etrailer!
