Features to know about

Smooth Ride Over Rough Roads: 8" Long Straight Equalizer Distributes Load Evenly

When your trailer hits bumps or uneven pavement, the suspension takes the beating. This 8" long straight equalizer connects 1-3/4" wide double-eye springs so the load transfers smoothly from one axle to the other. It helps the trailer ride steady by distributing weight evenly and letting each axle move just enough to keep things level and under control.

Built Strong for Everyday Hauling: Ductile Iron with Black Powder Coat Finish

A weak equalizer can wear out fast, especially under constant load. This one is made from durable ductile iron that stands up to heavy use. The black powder coat finish adds a layer of protection against rust and road grime, keeping the part looking good and lasting longer.

Precise Fit That Lines Up Right: Made for 1-3/4" Wide Double-Eye Springs

Getting the right fit makes installation smooth and performance better. This equalizer is designed for 1-3/4" wide double-eye springs with 9/16" spring eyes. It features a 9/16" center bolt hole and 9/16" outer bolt holes spaced 8" apart, with 4" between the center and each end hole. Everything lines up the way it should for a solid, reliable connection.

Simple Connection Points for Reliable Suspension Movement: Works with Shackle Straps and Center Hanger

This equalizer ties directly into standard suspension hardware. The springs attach to each end with shackle straps (sold separately), and the center mount hangs from a center hanger (sold separately). Once installed, it lets your suspension move freely to absorb shock and keep the trailer tracking true.

Great products and are operating very well.
Had
some issues understanding the electric over hydraulic pump wiring but was referred to the right person to walk me through it.

I had to replace one on my 2 horse trailer. etrailer made it easy when I ordered them. Replaced both side and everything bolted right up. Used so far for a year with no problems. I replaced all the bolts and sleeves. Perfect time to do it since your tearing into it. It will be trouble free for years. Excellent product.



by:

We haven't used the equalizers yet and won't until we need them. They are the right ones. Thus us the 2nd time we've ordered from your company and are pleased at the promptness of the delivery. Thank you:)

Perfect replacement!



by:

After a year I haven't used the part ordered. But it is exactly what I was expecting and as described. Maybe I can order some motivation to use parts and repair trailer!



by:

I used these to "level springs that had overly tall shackle brackets installed which rotated the axle seat downward too much. Worked out great.



by:

The item fit perfectly. Road test is ne xt.



by:

I have a huge old miley horse trailer that has seen better days and all of the leaf springs, bearings, etc needed to be replaced, It wasnt like I could go into a name brand parts store to get them either. So when my husband told me he found everything he needed on etrailer.com, I was relieved. I am very happy with the price and the delivery time. The fact that delivery was free was definitely a bonus because the parts were very heavy. I was a little worried about the condition of the parts when they came, the boxes were pretty beat up (very heavy) but so far I haven't found any problems.



by:

The holes are not round, therefore the bushings are pinched. I am going to put them in anyway because I replaced the nylon bushings with bronze bushings. They will work for a while.



by:

Third time I have ordered from e trailer and the first time they sent a trailer hitch reciever that was way out of square. Returned it and they sent another. That one was also out of square. Thankfully I had tools at work and could make it work. Now this time I ordered two of the same equalizers and they sent two completely different ones.

  • Suspension Kits for Different Tandem Axle Trailers
    Hi Richard, are you looking for replacement equalizers and shackle straps? Are the 7.5" and 8" measurements the width of your equalizers from center hole to center hole (measurement A in the attached picture)?

  • Availability of 8 inch Long Straight Trailer Suspension Equalizer
    We do not have any standard trailer equalizers that are 9 inches long from eye to eye. Is this a slipper spring setup by chance?

  • Determining Correct Replacement Leaf Spring For Trailer W/ 3000lb Axles and 27" Long Springs
    The # SP-210275 you were looking at is for a 3500lb axle and is 27" long measured from center of spring eye to center of spring eye. This is the correct spring for your trailer based on the measurements you provided. The next shortest spring would be 2" shorter which would be much too short. For replacement equalizers we have the # TREQR89 which is 8" long and has a center hole of 9/16", or the # TREQR83 which is 9" long and has a 3/4" center hole. For replacement hardware you can use...

  • Equalizers Needed for Blue Ridge Fifth Wheel Trailer
    When replacing equalizers, the length of the new equalizers needs to match that of the existing equalizers as closely as possible. The length of an equalizer is measured from center of bolt hole to center of bolt hole. Another measurement that needs to be taken into consideration is the height of the equalizer. The height of the new equilizer can be slightly different than the current height, but it should still try to be close to the existing equalizers' height. I have attached a diagram...

  • Replacement Suspension Components for 1970's Tandem Axle Horse Trailer
    We do have replacement parts for your trailer. Starting with the equalizer we have the # TREQR89. It sounds like you have 3-1/8" shackle straps so I recommend the MORryde Suspension Upgrade Kit # MR76ZR. This comes with wet bolts, bronze bushings, and 1/2" thick shackle straps. I believe you're talking about hangers when you gave those shackle dimensions. The closest we have to your front and rear are the # 115918 which are 2-3/8" tall. The closest thing we have to 6-3/4" is the 5-7/16"...

  • Availability of a 12 Inch Long Trailer Suspension Equalizer
    For double eye springs, the longest I could find was the 8 inch # TREQR83, or # TREQR89. But, for slipper springs, there are some longer options. Closest to 12 inches we have the 11-1/2 inch # TREQ4541. You will want to be careful when moving axles because if they are too far apart, one set of wheels could drag the ground as you turn. It could also change the tongue weight of the trailer and you will need to account for any changes made when towing. There could be additional different...

  • Is TREQR89 One Equalizer Or A Pair Of Them?
    Hey Kevin, the Straight Equalizer for 1-3/4" Wide Double-Eye Springs - 8" Long - 9/16" Center Hole # TREQR89 is for just one equalizer. We do have kits but those include hangers, shackles, bolts etc. What all are you trying to replace, and what trailer do you have?

  • Replacement Suspension and Brake Parts for a 1973 Bara LS Trailer
    Thank you for all of the info! Based on what you told me and the pictures you sent in separately I believe I know what you need. The brakes you need are the Electric Trailer Brake Kit # AKEBRK-35-SA which measure 10" x 2-1/4" and have a 4 bolt flange mounting pattern. I also recommend replacing your hub and drum assemblies as well. For this the Trailer Hub and Drum Assembly # AKHD-545-35-K should work but you will want to verify that your trailer currently uses inner bearing # L68149...
