Video Transcript for Redline Trailer Suspension SP05-060 Review

Today we're going to be taking a look at some nylon bushings. These bushings are designed for use with trailer suspension systems. You would simply insert them into the eyes of leave springs or the bolt holes of equalizers. They're going to help ensure proper sizing for suspension bolts. They're made from a durable nylon construction, the inner diameter, place a ruler on there, the inner diameter is going to be 9/16ths of an inch. Outer diameter is going to measure 3 quarters of an inch, over all length is going to measure 1 and 3 quarters of an inch.

All of these are going to measure the same and you're going to get a total of six nylon bushings. That's going to do it for our look at the nylon bushings that are designed for use with trailer suspension systems.

Nylon bushings are designed for use with trailer suspension systems. Insert them into the eyes of leaf springs or the bolt holes of equalizers to ensure proper sizing for suspension bolts.


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


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


It is hard to find such great quality and great service ANYWHERE these days, HOWEVER etrailer still has what it takes. The people always make a difference when you need help. A+
They have great Tech support online chat, email, by phone and even great tech articles.


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


They look good and better than what came off trailer. I like also have a clip around the leaves. I will move the AZ spring to left rear do to more arch for clearance. Will add new nylon bushing while doing the change. I am very happy with this order. Thank You for your help over the phone for this order.


Fits really good


Shipping packages everything looked to be tossed in a box without thought the ubolt packages were broke open and nuts fallen out. And with all of the transportation two of the nuts are not there. Now I’m going to have too replace them.

I will have our customer service team reach out to you.

Small order but treated like a large order. Fast, efficient and pleasant.
Very helpful.


Showed up on time. Everything fit good. Had good customer service with good information.


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!!


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.


Excellent replacement, fit perfect


All worked out very well


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.


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.


Everything went like clockwork and was easy to order and get info. Thanks,


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

  • 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.

  • 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.

  • 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...

  • 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.

  • Outer Diameter of Nylon Bushings # SP05-060 For Trailer Leaf Springs and Equalizers

  • 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...

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

  • 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 #...

  • 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.

  • 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...

  • 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...

  • 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...
