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. .

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 692736

Ask the Experts about this TruRyde Trailer Leaf Spring Suspension

  • 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...

  • Replacement Equalizer Measuring 6-1/8 Inches Long
    I do have all of the parts you need but unfortunately they are not offered in an all inclusive kit. Instead, you would need to purchase them separately. For this, you can use part # TREQ356 for the equalizer, part # 115052 for the shackle strap, and part # 166081 for the shackle bolt. I have attached a review video on each of the above parts for you as well.

  • Replacement Rubber Equalizer for the TREQ356 Curved Equalizer
    Yes, the E-Z Flex Heavy Duty Rubber Suspension System by Dexter Axle # K71-652-00 is the perfect replacement for your # TREQ356 equalizers. These are actually compatible as a replacement for equalizers that measure between 5-1/4" and 6-1/4" between the horizontal bolt hole centers (see attached photo). This equalizer has a vertical bolt hole distance that is 1/4" shorter than your current application but that is acceptable for this application.

  • 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...

  • Is the TruRyde Equalizer # TREQ356 Available In a Kit
    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. Your 2005 Keystone Outback 29FBHS should be a tandem axle trailer, so you will only need two equalizers. These equalizers are designed for 1-3/4 inch wide, double-eye leaf springs. 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...

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • Can 6-1/4 Inch Long Equalizers be Replaced with 5-3/4 Inch Equalizers
    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.

  • 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 leaf spring I recommend is 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles part # SP-053275. These leaf springs come with 9/16" diameter nylon bushings installed. 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...

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...

  • 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....

  • 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.

    Yes, the 4-Leaf Double-Eye Spring part # SP-212275 come with the nylon bushing which are inserted into the eyelet hole of each opening. The Never Fail Bushings part # LC279684 that you reference are not made of metal but instead a modified polyamide. The modified polyamide will last much longer than than standard nylon bushing and are also self-lubricating. They will work with the above leaf springs and the Curved Equalizer part # TREQ356.

    The Dexter E-Z Flex Heavy Duty Rubber Suspension System # K71-653-00 referenced in your question has a 7-3/4 inch equalizer and is intended for 8,000 pound axles. Based on the dimensions for your # TREQ356 Equalizer, which has a distance of 6-1/8 inches between the mounting holes, this may be a bit too large for a direct replacement. I instead recommend looking at the E-Z Flex # K71-652-00. These will fit in place of equalizers that are between 5-1/4 inches and 6-1/4 inches long. This...

    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.

  • 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...

As you can see the difference in the distance between the two attach holes on the bottom of the equalizer is 1/2 inches.
