I checked and I see that we are having the correct shackle straps sent out to you. Thank you for letting us know.

I have ordered from Etrailer a few times now, The service is always great and fast shipping. They have the best prices around. Where I live I have 24 miles of rough dirt road so am always replacing parts on my trailers. Their products hold up to the test of my road. Always a perfect fit too!

everything is still holding up very good! Thank you guys for the excellent service!

This hanger kit and leaf springs for my tandem boat trailer was PERFECT! I did one side at a time. Once we got the old crap off the trailer, reassembly was a snap. It took about three hours from start to finish. Most of the time was spend removing the frozen center bolt from the old equalizers. I'm very happy I opted for the two center bolts to be "wet bolts". Thanks again, I would definitely recommend etrailer to my friends. Regards, Bob

Still PERFECT



by:

Thank You for getting me back on the road quick , Awesome product thanks for the fast shipping, thank you Ed.



by:

Kit purchased to repalce damaged components on an existing 70's era trailer. The complete hanger kit was cheaper than purchasing the individual parts I needed. The hangers were not used but the equalizers, shackels, and bolts were direct replacements to restore my trailer to tip top shape. I added some nylon spring eye bushings to complete the job!

Everything went together well. The trailer is working fine now

I was very pleased with the quality of the APT4 kit I received . I had a small issue due to the kit was short 2 bolts and nuts. Etrailer toke care of the issue promptly by sending the missing parts with out question. I would use etrailer for all my future needs.



by:

Product was just as advertised. Nice to just order a kit and not have to worry about forgetting something. My only complaint was the packaging as everything was just loose in a cardboard box. Surprisingly nothing fell out in transit considering all the nuts, zerks and cotter pins were rolling around and there was a hole in the side of the box.



by:

Disappointed with the Made In China for the equalisers though quality seems to be ok.

Weld on pressings for the shackles and straps were poorly finished, with sharp edges that needed finishing before assembly/paint prep. Country of origin unknown.



by:

We have bought these hanger kits from etrailer before and are very happy with the product. Their shipping is quick and the value is exceptional.



by:

Impressed with quality of parts. Customer service was awesome in helping me find the right parts. Definitely will do business in future.



by:

The bushings seem cheap but otherwise seems to be solid.

I have ordered from etrailer many times and they are always prompt with their shipments and the parts arrive as ordered. Customer service A+.

Package arrived on time. All items in great shape. I'm looking forward to doing business with ETrailer in the future. Walker

  • Troubleshooting Rear Tires Wearing on Inside for Dual Axle 5th Wheel Trailer
    Thank you for all of that information. From everything that you described it sounds like you are overloading your rear axle. Even though your axles are rated for 8K each and you only have 12,420 lbs on your axles, if your rear tires are wearing on the inside tread then you have too much weight over the rear axle and you need to adjust cargo around in your 2019 Grand Design 367 BHS Reflection 41. Axles naturally have an arced shape and when they are weighed down correctly they straighten...

  • Raising the Height of a Travel Trailer that Rides Close to the Ground
    If the leaf spring stack on your travel trailer is currently mounted to the bottom of the axle, there is an over-under conversion kit that you could use to gain a few more inches of height. However, this will change the center of gravity on the trailer and can lead to an increased chance of trailer sway. For 3 inch round axles you could use # K71-385-00. And for 2-3/8 inch round axles use # K71-384-00. You should not have to do any welding to use these kits. You would not want to flip...

  • Replacing Trailer Leaf Spring Hangers
    Thank you for including your diagram, but unfortunately some of the information is not legible. In any case if you are replacing existing parts with different ones you will want to mock up the suspension set-up by first just tack welding the hangers. This will enable you to see if the whole system fits together and if you need to select a new equalizer. The linked diagram provides general axle placement guidelines for new construction. Generally, you want the eye of your spring to be...

  • What Is The Tallest Leaf Spring Hanger Kit We Offer?
    The tallest Leaf Spring Hanger Kit we offer is the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs - 3-1/4" Front/Rear, 5-7/16" Center # APT4 which uses 3-1/4" tall front and rear hangers, and 5-7/16" center hangers. The included equalizers are 6-1/4" long, and the included shackles are 2-5/8" long. The hangers will need to be welded to the frame of your trailer by a qualified welder. If you can tell me what the weight rating of your axle is I would be happy to recommend the correct...

  • How To Find Hanger Spacing When Using Tandem-Axle Trailer Hanger Kit APT4
    In regards to installing the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs part # APT4 with the 3-Leaf Double-Eye Spring for 2,000-lb Trailer Axles part # SP-169275, you'd just need to mock everything up on the trailer first before welding. We don't have guides to use for trailer hanger spacing for every equalizer and leaf spring combo unfortunately.

  • Will 5-7/16" Tall Center Hanger for Double-Eye Springs Work with 9/16" Bolt
    Even though the 5-7/16" Tall Center Hanger for Double-Eye Springs # 115919 has a 3/4" diameter bolt hole, this is actually designed to work with 1-3/4" wide double-eye leaf springs that install using 9/16" diameter bolts which I think is what you're getting at, so this should work perfectly for your application! If you check out the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs # APT4 you can see where these same hangers are used in a kit that comes with 9/16" bolts so having that...

  • Availability of Replacement or Repair Kit for TruRyde Trailer Suspension Equalizer
    We do have a Tandem Axle Hanger Kit # APT4 which comes with the equalizer you referenced, # TREQ458, as well as front and rear hangers, center hangers, shackle straps, shackle bolts, locknuts, wet equalizer bolts, castle nuts, cotter pins and grease zerks.

  • How Much Should Wet Bolts be Tightened Down for Hanger Kit # APT4
    When installing the wet bolts, like what comes with the Hanger Kit # APT4 that you referenced, we recommend tightening them down so that the knurls are no longer visible and then backing them off just a little bit. There is no torque rating for wet bolts and you are correct that if you tighten them down too much then it will "lock up" your suspension some. If you follow the procedure highlighted above you will have them tightened correctly.

  • 5th Wheel Trailer Rides High In the Front When Connected to a 2015 Ram 2500 4x4
    You covered the basic ways of adjusting the height of a 5th wheel trailer (lowering the hitch and raising the pin box). And since the axles are already below the leaf spring stacks there is one other thing that you can do to get more height at the rear. You can have the existing suspension hangers cut off and new, taller ones welded on. We have several heights of hangers available and I have included a link to the hanger main page for double eye leaf springs for you. The cutting and welding...

  • Getting More Ground Clearance on a 2012 Lance 1575 Travel Trailer or Other Trailers
    I have a couple of options that will give you more ground clearance depending on how your 2012 Lance travel trailer is set up. First, if the trailer uses double-eye leaf spring suspension AND the axles are on top of the leaf spring stack, AND if you have a 2-3/8 inch diameter round axle, you can use over/under conversion kit # K71-384-00 to move the leaf spring stack to the tops of the axles. For a 3 inch diameter axle use # K71-385-00. If the trailer does not fit the criteria above then...

  • Recommended 7-3/4 Inch Suspension Equalizer with 3/4 Inch Center and 9/16 Inch Bottom
    The Tandem-Axle Trailer Hanger Kit for Double Eye Springs - 3-3/4" Tall Front/Center/Rear # APT5 has the wider 7-3/4 inch equalizers you referenced but all holes are 9/16 inches (top and bottom). All of our kits will have the 9/16 inch bolts. This isn't an issue unless you aren't replacing the hangers. We do have the equalizers you are seeking sold individually. They are the Curved Equalizer for 1-3/4" Wide Double-Eye Springs - 7-3/4" Long - 3/4" Center Hole # TREQE34. Then you can...

  • How to Add a Lift to a Toy Hauler Trailer for Better Ground Clearance
    You can lift your trailer by taking the axles of the trailer and moving them below the leaf springs. Depending on the amount of leaves on your leaf springs this should give you about a 4-6 inch lift. The diameter of your trailer axle will determine the size of the parts that you will need to order. If your axle is 3 inches diameter, the Dexter Trailer Springs Over-Under Conversion Kit, # K71-385-00, would be a great choice and if your axle is 2-3/8 inch diameter you could use the Over-Under...

  • Distance Between Hangers with 26 Inch Leaf Springs
    We don't carry the MR4 leaf springs but based on my research they look like they are 26 inch double-eye springs like part # e94SR. For springs of this length and the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs # APT4 the hangers are going to be spaced 30-1/4 inches apart. I have added a link to a video review of the hanger kit as well as a couple help articles on trailer suspension which I recommend checking out.

  • Correct Hanger Spacing for the Tandem-Axle Trailer Hanger Kit Part # APT4
    The position of the axle should dictate the position of the springs and hangers not the other way around. With that being said, in order to determine proper placement of the hangers you will want to take the the distance between the two eye holes on the leaf spring which on part # e54SR is 25-1/8". Add that to half of the length of the equalizer from the center of the two lower bolt boles which for the one included in part # APT4 is 3-1/8". You would then need to subtract 1/2" for the shackle...

  • Replacement Suspension Kit For Tandem Axle 1 3/4 Springs With 7-3/4 x 2-7/8 Inch Equalizers
    In order to retain your current suspension geometry, you'll need to use an equalizer of the same length and height as the 7-3/4 x 2-7/8 equalizer you currently have. The Dexter Axle # K71-449-00 offers equalizers that are the same width and height as what you have now. The only difference is that the shackle links are a tiny bit shorter, at 2-1/4 inches versus the 2-1/2 you currently have. This difference is very small and won't be enough to have a negative effect on your suspension geometry. Thanks...

  • Recommendations for Lifting Travel Trailer About 3 Inches
    To raise your travel trailer about 3 inches, your best option is to use an over under kit like # K71-384-00 for 2-3/8 inch diameter axle or # K71-385-00 for a 3 inch axle. These kits will convert your axle and suspension so the axle will be under the leaf springs so it will raise your trailer the diameter of your axle plus the height of your leaf spring stack. Another option is the Lippert Components Center Point by Trailair Air-Ride Suspension Upgrade - Tandem Axle # LC1565391 which...

  • Is Welding Required to Install the Tandem-Axle Trailer Hanger Kit # APT4 on a Trailer

  • How Can I Get More Ground Clearance if my Axles are Already Converted Under the Springs
    From that point the only option you will have to raise your camper would be to add longer spring hangers. Depending on your setup you can get a couple of inches out of these. Measure yours from the frame to the bolt hole and get longer ones like the Front/Center/Rear Hanger for Double-Eye Springs part # 28-5 that is 3-1/4" tall. The Tandem-Axle Trailer Hanger Kit for Double-Eye Springs Kit part # APT4 is also a great way to achieve this and refresh all of the other suspension components.

  • Options to Lift a 2003 Keystone Fifth Wheel Trailer
    One option you have would be to move your axles to below the leaf springs. This is the most common way to lift a fifth wheel trailer to allow the trailer to be towed level if the hitch and pin box adjustments are maxed out. The diameter of your trailer axle will determine the size of the parts that you will need to order. If your axle is 3 inches diameter, the Dexter Trailer Springs Over-Under Conversion Kit, # K71-385-00, would be a great choice and if your axle is 2-3/8 inch diameter...

  • Adding Lift To 2003 Jayco Single Axle Tent Trailer
    I spoke with my contact at Jayco about your 2003 single axle trailer. There is no lift kit available but we may have an option for you. If your 1-3/4 inch axle is round and you have underslung leaf springs, I recommend installing a new spring seat on top of the axle, like the Spring Seat for Typical 2000-lb, Round Trailer Axles, part # TRSS175. Simply flipping the axle is not an option because axles are made with a slight arc so that they can handle the load on the trailer. When placed...

  • How Much Space Should be Between the Top of the Axles and the Bottom of a Boat Trailer
    Normally when using hanger kit # AP233-H248 with spring # e66SR the distance from the bottom of the frame to the center of the axles is going to be approximately 4-1/2 inches. Subtract half the width of the frame then to the top of the axles that would be 3-5/16 inches. Two inches might work out fine depending on how far the suspension travels but more height would likely be needed considering the heavier load. Hanger kit # APT4 would provide more height since it has taller hangers than...

  • Way To Raise Trailer Suspension When Axles are Under Leaf Springs
    If your axles are currently under the leaf springs then an over-under kit would not be the correct product to use as it would not actually raise your trailer. It would lower it. If you cannot use an over/under conversion kit then the only other way to raise the height of the trailer is to have the old suspension hangers cut off and new, taller ones welded on by a qualified professional welder. I have included a link to the hanger main page for you. You can also try raising the pin box...
