Good products and good service



by:

Great products, great service.



by:

Great product, put the trailer together last night. It matched the original perfectly. Noboby seems to carry trailer parts locally anymore. Will definitely be going back when i need other trailer parts.



by:

Called in to order a suspension kit (#AP233), which does not include nylon bushings for the leaf spring eyelets. These bushings were recommended given how many were needed for the leaf springs.
These bushings are the wrong size. The outside diameter is 3/4. My application needs 11/16. These bushings won't even fit the suspension kit equalizers in the same sales order.



by:

Fit my trailer spring set perfectly. Time will tell how long they'll last but the springs are not rattling on the bolts any longer. I'm very satisfied.

That's awesome! Glad to hear that :) What's next on the reno list?

Needs to be in a package of 8



by:

The bushings are excellent, quality is great. this was the final piece to my trailer suspension replacement. Unfortunately I apparently ordered the wrong ones, not to worry, was able to turn down the od and drill id to fit my 3500 lb. assembly. the complete job was a success. All parts were great fit and quality. Should you undertake this job, suggest to torch old parts off. It then takes about an hour to do complete job. Great parts.... picture of final job attached



by:

Excellent service. Good prices and had the right part. Fast shipping. Will do business with again



by:

I had several trailer parts that I was needing to order and was not sure what part numbers, I needed. Alex was very helpful informing me with what I was needing and got them ordered. Very knowledgeable and helpful.



by:

Quality bushings better that original e quipment



by:

Couldn't find these anywhere in town th anks



by:

All worked out very well



by:

I put these bushings on my utility trailer a year ago and they are still looking brand new. I've hauled about 40 yards of 3/4 down gravel(2 yards at a time) to my cottage for a 60 mile trip. Plus numinous moves so they are getting a good workout.



by:

Quick service, great product!



by:

Ordered bearings and races for both hubs on my bass boat. Quality seemed better than local auto parts bearings. Also purchased other items on this order and was very pleased with products and customer service I received from etrailer. Informative, fast shipping, and courteous company to work with. Top notch!!



by:

These are great, all of the bushings in my leaf springs were shot and adding to the clunking sounds coming from the open trailer. These are an easy install when refreshing the rest of the suspension components



by:

I installed these on my utility trailer. They fit perfectly and took all the play out of the spring ends. I only use the trailer occasionally and I have not had any problems with them so far. I was amazed that etrailer had such a broad range of sizes of this product to choose from. Thanks etrailer



by:

The 3/4 inch spring shackle bushings were a perfect fit and installed very easily. Local trailer supply stores did not offer the 3/4 version and I was able to get them from etrailer in three days. I found the sales representative I called to be very helpful and professional.



by:

The parts I needed were difficult to impossible to find here in the northeast.
You website made it real easy to find what I needed to restore my flatbed trailer.
Thanks



by:

Yes, everything is working well.



by:

Note these are nice nylon bushings but beaware they most likely will not fit if your spring eye measures 3/4” -0.750 id . Spring eye id will have vearing tolerances, and these bushings will not fit . Get the bushings that have a 11/16 OD . I had turn these down to fit my springs



by:

This is my 3rd order from etrailer. They make ordering easy online due to pictures and detailed description of all products. They also have a very large inventory of hard to find parts and the prices are very fair. Very highly recommended. Thanks etrailer !



by:

I have an older "home made" trailer and these bushings were the perfect part for the application.



by:

The bushing kit arrived just as described and turnaround time for the order was great for a delivery to Hawaii during Christmas week.

The bushings were just what was needed and fit the leaf springs without a hitch.



by:

The nylon bushings ordered were the perfect fit and size. There is a lot of different sizes of bushings and etrailer. com has them all. Service was fast and received when Nicky said the order would.

  • Which Replacement Equalizer and Shackles for 2004 Carson Dump Trailer with Axles 34" Apart
    In addition to the axle spacing, the best way to choose the appropriate equalizer replacement is by measuring how wide your current equalizer is when measured between the two side bolt holes, center on center; as long as you keep everything relatively close in length compared to the old parts, the geometry of your suspension system won't be thrown off. As long as your existing equalizer is 5-3/4" wide and your shackle straps are 2-1/4" long from bolt eye center to bolt eye center then...

  • Comparing Bronze and Nylon Bushings for Trailer Suspension
    It really just depends on what you are looking to get out of the bushings. Bronze bushings, like part # K71-291-00, will last longer but are more noisy and it is recommended to use wet bolts like part # 126B2 to keep them lubricated. Nylon bushings, like part # SP05-060, are much quieter and can be used with regular bolts like part # 166081 since they don't need to be lubricated as much. As far as lifespan goes the bronze will last longer but not so much longer that they are much better...

  • Replacement Leaf Spring for 2019 Forest River Salem FSX 197bh
    I need more information to assist you with your trailer spring replacement. If you measure from eye to eye (center of the bolts) I can help you with the correct replacement for your needs. Leaf spring replacements are dependent on the length and also the capacity, which giving me your model helped me with the capacity part but not the length of spring. It seems with that new a trailer, you shouldn't need new springs yet. You may just want to replace the spring bushings with # SP05-060...

  • Are There Bronze Leaf Spring Bushings 3/4" OD x 9/16" ID
    I do have an option for you although we don't have any bronze bushings in the size you listed. That said, we do offer nylon bushings which measures 3/4" O.D. x 9/16" I.D. x 1-3/4" Long part # SP05-060. These can then be used with the Shackle Bolt with Locknut for Double-Eye Springs part # 166081. This would still be a great improvement to the trailer allowing for easy maintenance.

  • Trailer Leaf Spring Bushings with 9/16 Inner Diameter and 3/4 Outer Diameter
    There can be some slight measurement differences among the various bushings of the same part number. So if you went with a 9/16 inner and 3/4 outer, like # SP05-060, then it will work though it is possible that the fit will be tighter for some than others especially since there are tolerances in the spring eyes as well.

  • Availability of Nylon Trailer Leaf Spring Bushings

  • Equalizer Bushing Size and Compatibility
    The only bushings we have that are 9/16" Inner Diameter, 3/4" Outer Diameter, and 1-3/4" Long are Nylon Bushings item # SP05-060. The bronze bushings from the MoRyde Suspension upgrade kit Item # MR46ZR would not fit in the TruRyde Equalizers item #TREQR2. The bushings are Outer diameter 11/16" and the Inner diameter is 9/16". The TREQR2 equalizers have a 9/16" bolt-hole diameters.

  • 1-3/4 inch Nylon Bushing Kit Recommendation for Trailer Suspension
    Are you sure the inner diameter you need isn't 9/16 inch as that's the more common size that matches up with the rest of the dimensions you listed. For that we have the part # SP05-060 which is a nylon bushing kit that has an inner diameter of 9/16 inch, outer diameter of 3/4 inch and length of 1-3/4 inch.

  • What Leaf Spring Bushings Will Work With My 3" Shackle Bolt W/ Locknut For Double-Eye Springs
    Using the Shackle Bolt with Locknut for Double-Eye Springs - 3" Long, part # 166081, indicates that your leaf springs are 1-3/4". If that is the case, the bushings you need have an inner diameter of 9/16" and an outer diameter of 11/16". Something like the Nylon Bushings - 9/16" Inner Diameter, 3/4" Outer Diameter - 1-3/4" Long - Qty 6, part # SP05-060, will work. We do have other options. I have included a product description link, demo video links, and a weblink to our bushings for...

  • Availability of 9/16 I.D 3/4 O.D Nylon Bushings For Trailer Suspension
    The Nylon Bushings - 9/16" Inner Diameter, 3/4" Outer Diameter - 1-3/4" Long - Qty 6 # SP05-060 you were looking at are the only option for bushings in this size. While the 9/16" inner diameter is common, the 3/4" outer diameter is not very common which is why there is only one option. The more common outer diameter is 11/16" which is 1/16" smaller. I recommend double checking the inside diameter of your springs/equalizers once the old bushings are removed with digital calipers like #...

  • Do All Suspension Bolts for Leaf Springs Need a Bushing
    You need to have a bushing installed on each bolt that comes in the Single-Axle Trailer Hanger Kit for Double-Eye Springs # APS4. For this I recommend picking up the Nylon Bushings # SP05-060 which have the appropriate inner diameter and length for the hangers, and comes with 6 bushings to match the number of bolts in the kit. The only thing you'll need to check on is the 3/4" outer diameter to make sure these fit inside the leaf springs (if your leaf springs didn't come with bushings).

  • Leaf Spring Bushings that Have Outer Diameter of 3/4 inch

  • Equalizer Upgrade for 2018 Grand Design 285BHTS Trailer Trailer
    In order to use the # LC696740 Lippert Road Armor cushioned equalizer kit, you'll want to go with longer shackle links, assuming you're currently running 2-1/4 inch links. Going with a 3-1/8 inch link will make up that width difference. Lippert recommends the # LC52SV AP Wet Bolt/Shackle link kit for use with the Road Armor equalizer. The MORyde # MR98ZR is designed for suspensions that use their Correct Track suspension system. The Lippert Never fail kit has been discontinued. Another...
