Brandon was very knowledgeable about what I would need to replace my axles and springs, right down to the sizes for bushings and bolts. I have been using trailer for many years because their service is awesome.



by:

Excellent service and prices. Needed to replace curved equalizer, shackles and bolts, nylon spring bushings, u-bolts, and wheel bearing seals on my sailboat trailer. etrailer had everything and shipped it fast. Staff at etrailer was excellent!



by:

These were just what we needed for repairs on our 1983 stock trailer. The old parts were quite worn. We gave the trailer a face lift as well, and it should last another 37 years.



by:

Please let your purchasing agent know that this is a very poor quality product. The tolerances were off and just sloppy workmanship. If time would have permitted the product would have been returned in the hope of finding a better made item.



by:

E trailer had the exact parts I needed. This was an exact replacement for my worn out parts.



by:

I have a old trailer with nonstandard parts. Eric's tenacity and determination ensured we selected the parts that would fit the old trailer. All parts arrived as expected and fit like original. Could not have done it without Eric.



by:

The parts arrived days before we expected. We had the job done before we expected the parts. Thanks for your service.

Parts are O.E. for my trailer . Part is a match for my old part.

I had already purchased a Heavy Duty Kit but the equalizer was not the correct one for my equipment. When I called to see if you had the correct equalizer your rep. couldn't
find the 356 part I needed and we settled on a more triangular one that had the right measurements for the bottom width ( 6 1/4") of my o.e. but was an 1 1/2" higher. After I hung up from him I searched you web site and found the right TREQ356 part listed.
I tried to get him back on the phone / and left him a message. I called back got another rep. got the right part ordered and he sent me a shipping label to return the part that was actually the wrong part for my trailer.
So Thank You very much for your swift attention to my problem. Everything else in the Heavy Duty Kit is enter-changeable and seems to fit great.

Part Well Done



by:

Our trailer is just like the one in the video that demostrates changing the equalizer and shackle straps. This equalizer was the closest in size to our old one although the height is shorter but the trailer sat too high anyway. We changed all the shackle bolts,bushings and shackle straps. It took 3 hours and 2 people, but I have to say the trailer now rides real smooth and quiet. The real test will be when we need to haul the next load of livestock. Very happy with the quality and fast shipping.



by:

Perfect fit. Fast shipping.



by:

These suspension parts are a perfect fit and have solved my utility trailer problems. Great help from etrailer and a great information packed web site.



by:

It's an equalizer, looks like a caste part, not machined. It did come with bushings, a point that I would like to have known, because I now have more inserts on hand than I need.

My total order included bolts, shackles and bushings. Prices for these parts were very competitive for the market place. However the cost for standard shipping was pretty much out of line. Also, for the amount paid for shipping, eight days to receive was a little slow.

On the plus side, installation was a breeze, and any questions that I might have had were more than adequately addressed on the web site.



by:

Worked out great!



by:

Fit perfect and for the price it wasn't worth my time to install bushing in the old one! E trailer makes it only an hour job to completely rebuild a tandem axle trailer suspension.



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:

Arrived in a timely manner. They are the exact replacements for the original equalizers.



by:

replaced the suspension on my 5th wheel--all went well and now I am much releived to lub with a grease gun and not a oil can. one of the wet bolts was defective--I called you sent one out quickly--thanks



by:

My boat trailer broke and I needed to replace the entire suspension system. I called around to local businesses and would have to wait several weeks for them to order the parts. I began searching online and found etrailer.com. I looked up the parts I needed and all of them were in stock. The shipping was free and the parts were received sooner than I could have ordered them from a local retailer. Also, the price from etrailer.com was cheaper than what I would have had to pay locally. I am very pleased and will continue to use etrailer.com for all of my trailer part needs. I plan on telling everyone I see about my experience and suggest they use etrailer.com as well. Thank for helping me fix my trailer. I will post pictures when the job is finished.

Was an exact match for original.

  • Replacement 2-1/4 Inch Shackle Straps and EQ-356 Equalizers for Tandem Axle Trailer
    You definitely have the right idea of replacing everything if your suspension parts are rusting. To replace the 2-1/4" (center-eye to center-eye) shackle straps I recommend the MORryde Suspension Upgrade Kit for Tandem Axle Trailers # MR46ZR. This not only comes with the shackle straps but it also comes with the wet bolts, nuts, and bushings for a complete overhaul. To replace your equalizers you need the part # TREQ356 (unless you want to upgrade to something fancier) and then for your...

  • Wet Bolt Kits With Bronze Bushings For the Curved Equalizer # TREQ356
    You can add either the MORryde Suspension Upgrade Kit with 2-1/4" Shackles # MR46ZR or 3-1/8" Shackles # MR76ZR to a pair of the Curved Equalizers # TREQ356. These upgrade kits include bronze bushings and wet bolts which allow you to grease the suspensions so it is able to articulate your axles more easily. The also have thicker shackle links which are not going to oblong after years of use and need replaced.

  • Recommended Heavy Duty Shackles and Wet Bolts Compatible With Curved Equalizer TREQ356
    I would be happy to recommend the correct components for you, but there is not a kit that includes the # TREQ356 you were looking at and heavy duty shackles. Instead you will need to purchase the # TREQ356 separately and then the MORryde Suspension Upgrade Kit for Tandem Axle Trailers - 2-1/4" Long Shackle Straps # MR46ZR. This kit includes bronze bushings for the equalizers and the springs, wet bolts, and heavy duty shackles. Currently there are no heavy duty shackles that are 2-1/2",...

  • Recommended Replacement Equalizer for a 2022 Forest River Sandstorm 272SLC
    Hey David, so for MORryde it looks like the closest option they have to what you need is going to be the MORryde Rubber Equalizers for Tandem Axle Trailers # MR87ZR which has a 6 1/2" bottom hole spacing from center to center. Lippert also offers an equalizer upgrade that is much closer to what you need with # LC696740. These equalizers have a 6" bottom hole spacing from center to center. Apart from that, your only real option would be to use a standard equalizer # TREQ356 to replace...

  • Availability of Tandem Axle Equalizer Kit Like # AP233 But With 6-1/8 Long Equalizer # TREQ356
    We do not offer a tandem axle trailer equalizer kit like # AP233 that includes 6-1/8-inch equalizer # TREQ356. However, you can order the individual parts equivalent to a kit. Shackle straps (2-1/4-inch) are part # TRSL225; Shackle Bolt with Locknut is part # TRFA73Z916DLNZ.

  • Limited Tire Clearance with Stock Tire Size on a 2006 Forest River Cherokee 27Q
    We recommend having a minimum of 3" between the top of the tire and bottom of the fender in order to allow for proper suspension travel. However, based on the photo you sent I believe you need new leaf springs as the ones you have appear to be almost completely flat. This has then compromised your tire clearance. The flattened leaf springs could either be a result of overloading the trailer or just general wear. In order to replace them you would need to know your axle capacity and the...

  • Curved Equalizer # TREQ356 Recommendation for a 2004 Wildcat 5th Wheel Trailer
    Based on the measurements that you gave you would want a TruRyde Curved Equalizer, part # TREQ356. Even though it only seems like the E-Z Flex heavy duty rubber suspension system # K71-652-00 is a little bit smaller, it would not work for you.

  • Equalizer/Hanger Kit Recommendation with Equalizer TREQ356
    We can piece together an equalizer kit for you, however the TruRyde Equalizer, # TREQ356, is not included in an equalizer kit or a hanger kit. Next, you will need 14 shackle bolts that are 3 inches long and have a 9/16 inch diameter. For this, you can use Shackle Bolt, # 166081. Finally, you will need 8 shackle straps. The most common size is the 2-5/8 inch shackle strap, # 115052. I recommend measuring your current shackle straps to verify you are buying the correct replacement shackle...

  • Replacement Trailer Suspension Components For Tandem Trailer
    We do not have any equalizers with the dimensions you mentioned. From the looks of the photo you sent it appears the hole may be elongated and you may be able to use an equalizer that has all of the holes at 9/16-inch like part # TREQ356, or with a center hole that measures 3/4 inch like part # TREQ458. You will need to measure the equalizer length and height as well as the holes like the attached drawing shows to find the correct replacement. It looks like the shackles and bolts...

The closest equalizer we have to what you need is the part # TREQ356 which measures 6-1/8 inches from bolt hole to hole front to back and vertically is 2-1/2 inches.

What you want is a system with an equalizer as close to your measurements as possible, and for that what you can use is the Lippert Road Armor: - Road Armor Shock Absorbing Equalizer Kit - Tandem Axle # LC696740 The # LC696740 measures 6 inches apart from...

    We currently will not have a kit that contains everything that you are looking for but we do have all the parts you will need. First I recommend upgrading your equalizers to the MORryde Rubber Equalizers for Tandem Axle Trailers # MR87ZR. These cushioned equalizers will help to extend the life of your suspension components by absorbing the harsh road shock and reducing back and forth chucking. This will equal a better ride for your horses as well. Pair this with the MORryde Suspension...

  • Will Anything Bad Happen if Too Big of Trailer Suspension Equalizer is Used
    Your equalizers not sitting level is a sign that they aren't going to work as well since the movement they normally allow will be limited. It may not be a problem in the near future but basically components of the suspension will wear out quicker and your tires may wear out quicker as well. It would be best to replace what you have with the correct size equalizer like the part # TREQ356.

  • Selection of Correct Dexter EZ Flex System to Replace EQ-356
    The equalizer you currently have on your trailer is the Curved Equalizer # TREQ356 that has 6-1/8 inches between the mounting holes horizontally and 2-1/2 inches vertically. The closest EZ Flex to what you have would be the # K71-652-00 which has a horizontal measurement between bolt holes that ranges from 5-1/4 inches to 6-1/4 inches depending on how much the equalizer compresses and a vertical height of 2-1/4 inches.

    No, none of the suspension hanger kits we have use equalizer # TREQ356. You would have to get the parts individually or get a kit with the proper sized hangers and shackle straps and just add additional equalizers. For a 2-9/16 inch hole center to center shackle strap we have # TRSL256. For bolts you can use # 126B2 for a wet bolt and nut or # 166081 for a regular bolt with nut. For the hangers though there are lots of options and I don't know exactly what you need so I have included...

The amount of leafs do not matter as much as long as the spring is rated for your axle capacity. I recommend TruRyde Shackle Link part # TRSL225. The shackle straps are 2-1/4" long. The bolts you need are part # 166081. I also recommend curved equalizers part # TREQ356 that measure 6-1/8" long. We do not carry an equalizer...

  • Can I Replace TREQ104 Equalizers With TREQ356 And What Difference Will It Make?
    You can replace the Curved Equalizer for 1-3/4" Wide Double-Eye Springs - 5-3/4" Long - 9/16" Center Hole, # TREQ104, with the Curved Equalizer for 1-3/4" Wide Double-Eye Springs - 6-1/8" Long - 9/16" Center Hole, # TREQ356. Even though you can replace these parts, moving to a longer equalizer will cause one axle to have a disproportional amount of weight on it. The smooth transfer of the impact won't be distributed as effectively which will cause a rougher ride without as good traction....

  • Vintage Trailer Suspension Replacement Recommendations
    Going to a higher rated spring will not give you higher rated axles. The axles themselves have their own rating independent of the springs. So going to a higher rated spring would only increase your trailer capacity if they were the weakest link prior to replacement. That being said, your current springs are 28 inches long so you will want to pick out a spring that is slightly shorter than that as springs tend to stretch over time. The part # SP-210275 would be the best candidate as it...

    The suspension kit, part # K71-359-00, will fit your toy hauler. It's only a 1/2 inch shorter so you're only losing a 1/4 inch on each side. If you really want to keep longer equalizers you can use the # K71-359-00 kit but replace the equalizers with part # TREQ356 that are 6-1/8 inches long.

    The correct E-Z Flex Heavy Duty Rubber Suspension System to replace the Curved Equalizer part # TREQ356 on your 2016 Coachmen Apex 287BHSS is part # K71-652-00. The axle spacing listed for the E-Z Flex System is just a guide. If the dimensions of the equalizers match or are very close like in your case then you can use the E-Z Flex System without issue. The shackle straps and adjustable arms on the E-Z Flex System will even out the difference in equalizer dimensions.
