Video Transcript for TruRyde Trailer Suspension - Leaf Spring Suspension - TREQ356 Review

Today we're going to be reviewing part #TREQ356. This is the TruRyde Curved Equalizer for 1-3/4" wide double-eye springs. It's going to connect the double-eye springs on dual- or triple-axle trailers. Springs attach to the ends of the equalizer with shackle straps. Those are going to be sold separately, and then the equalizer is going to be suspended from the center hanger, which is also going to be sold separately. This system is designed to transfer the load in sudden impacts from one axle to another by permitting movement between the axles. It's going to help distribute weight evenly, and it's going to result in a smoother ride for the trailer. It does include the bushings. Those are located inside each hole.

This is designed for 1-3/4" wide double-eye leaf springs with 9/16" spring eyes, so the center bolt hole diameter up here is going to measure 9/16" and then the left and right bolt hole diameters are also going to measure 9/16". When choosing an equalizer, it's really important to know a few measurements. You definitely want to know the diameter of each hole, so, again, each one is going to measure 9/16". And then a few more measurements to go over. We're going to measure from the center of this hole to the center of this hole. So, taking that measurement, it's going to give us a measurement of 6-1/8". Then we want to measure the distance that we have from the center of this hole at a straight line to the center of this hole, so we don't want to measure the angle.

We would actually want to measure at a straight line, so create an imaginary line going across here and measure down to that line. That measurement would measure 2-1/2". Keep those measurements in mind. I believe that's going to do it for today's review of part #TREQ356. This is TruRyde's Curved Equalizer for 1-3/4" wide double-eye springs. .

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




by:

Perfect, exact equalizer as original on trailer constructed in 2001. Oh, ordered on Monday and arrived early at 9:15PM Thursday September 1st by normal ground transportation




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:

Equalizers worked perfect. Trailer is repaired and back to work.

Great quality, didn’t have the specific ones in stock and was given another option to get them sooner from a different brand. Great customer service and communication.




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:

Perfect replacement part, reasonable price, delivered on time.

Exact duplicate to what I had.

Very fast shipping!




by:

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




by:

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

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:

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.




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:

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:

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:

Staff was very helpful and product was delivered on time. Thank you




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:

Very happy with all of the items that I ordered from etrailer.com last year. Etrailer.com is a first class merchant and is my preferred source for all things related to towing/trailers.




by:

Bushing holes are rough with slag in them. Make sure you have a strong reamer / drill bit to clean them out. My buddy warned me beforehand and provided the drill bit. Glad he did or I'de be up on jack stands!




by:

I replaced the plastic bushings with the bronze bushings, and added a grease zerk at the pivot. With the shackle bolts being wet bolts I'm sure this will be a great upgrade to my trailer suspension.




by:

The perfect replacement parts. The job went exactly as planned. I got the parts in just a few days just as etrailer said I would.I will recommend etrailer to anyone needing trailer parts. Thank you very much for your help...

See what our Experts say about this TruRyde Trailer Leaf Spring Suspension

  • Correct Replacement for 6-1/2" Long Equalizer
    I do have some options but that is not a standard equalizer measurement, the closest we could get is the Curved Equalizer part # TREQ356. There would be no kit for this and you'd have to adjust the shackle strap length for the difference in equalizer dimensions. I have attached some shackle strap options below.

  • Can Trailer with Square Axle be Lifted if Axle is Above Leaf Spring
    If you moved the axle to be below the leaf spring the trailer will have gained the additional height of the axle diameter and the spring pack thickness. Since square axles typically don't have a bow or a spring seat it should be just a matter of moving the axle to other side of spring.

  • What are the Proper Torque Specs For TruRyde Curved Equalizer # EQ-356
    When installing an equalizer such as TruRyde # TREQ356, there is not a specific torque rating that adheres for suspension bolts. The rule is to tighten to snug while allowing minimal movement. The locking nuts are a one time use piece. Ideally, you should see 2 bolt threads when you have completed tightening the equalizer bolts. I have attached a short video where the equalizer is replaced on a trailer.

  • Raising the Height of a Boat Trailer with Square Axles Mounted Under Leaf Springs
    Since the springs are already on top of the axles on your boat trailer what you can do is have a professional welder remove the existing leaf spring hangers and weld on new taller ones. This is pretty much the best way you will be able to get extra height on the trailer. I have included a link to the hanger main page for double-eye leaf springs.

  • Are Equalizers Recommended Between Tandem Trailer Axles
    You will want to use an equalizer on your trailer if you go to a tandem axle setup. You wouldn't be able to install the axles closer together by not running one anyway. You would have to run two sets of single axle hangers. Which when you put the two hangers next to each other it wouldn't let you install the axles any closer than if you had one hanger with an equalizer. Plus, your suspension would be smoother with an equalizer since it would let the axles pivot up and down slightly over...

  • How to Find the Correct Replacement Equalizer for a 1999 Bonanza 3-Horse Trailer
    If your trailer suspension seems to be in good shape, other than the broken equalizer, then you do not have to replace both sides if you do not want to. The best way to find the correct replacement equalizer is to measure the shackle bolt holes and make sure you choose the correct style equalizer (double-eye vs. slipper). For example, the TruRyde Curved Equalizer, # TREQ356 (pictured), measures 6-1/8 inches long from bolt hole to bolt hole on center and it is 2-1/2 inches tall from bolt...

  • Equalizer Replacement Recommendation for 1977 Ideal Trailer
    The equalizer part # TREQ356 would work well for you. It would be an inch shorter vertically but that can be compensated for with longer shackle straps or hangers if you think it would be a problem. In most cases it's not a problem though.

  • Correct Equalizer for Rvison Trailbay 31BHSS Travel Trailer
    I'm assuming that your existing equalizer is 6-1/8 inches long, measured center hole to center hole. If this is the case, we don't offer an equalizer that's 6-1/8 by 2, but we can get you really close with part # TREQ104 which is 5-3/4 inch long by 2 inches tall. The 3/8 inch shorter equalizer will slightly change the angle of your shackle links, which will actually allow a bit more suspension articulation.

The 3/8 inch shorter equalizer will slightly change the angle of your shackle links, which will actually allow a bit more suspension articulation.

  • 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....

  • 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...

  • Looking for Curved Equalizer Hanger Kit for Double Eye Springs
    It sounds like you're looking for something like the kit # APT5, which come with 7-3/4 inch equalizers instead of the 6-1/8 inch. If you already have the 6-1/8 inch equalizer this kit will work for you. Purchasing as a kit like this will be more economical that piecing everything together, like you mentioned. We don't carry the kits without an equalizer and we don't have a kit that includes 6-1/8 equalizers. If you need the equalizer as well then you'll need part # TREQ356.

    We have 6,000 lb trailer leaf springs that are 25-1/4 inches long with the part # SP-111275 which would be exactly what you are looking for. 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. If you replaced all or your equalizers with this it would fit and work well.

    Yes, the Road Armor Shock Absorbing Equalizer Kit # LC696740 can replace the equalizer part # TREQ356 that you have since the horizontal bolt holes are the correct distance apart. Since the vertical bolt hole distance is an inch taller though you would want to go with longer shackle straps. This will allow your leaf spring to sit level.
