Features to know about

Smooth Ride Over Every Mile: 5-1/2" Long Straight Equalizer Keeps Axles in Sync

When both axles aren’t working together, every bump and dip gets magnified. This straight equalizer connects your double-eye springs on tandem or triple setups so the axles move evenly. It transfers the load and sudden impacts from one axle to the other, spreading out the stress so your ride stays smooth and your cargo doesn’t get tossed around.

Reliable Fit for Standard Hardware: 9/16" Center and Side Bolt Holes

Matching hole sizes make assembly simple. The 9/16" diameter center and side bolt holes line up with standard suspension bolts, so it hooks right into your existing setup. It’s designed for 1-3/4" wide double-eye springs, giving you a direct fit that restores proper motion and balance between axles.

Built to Handle Everyday Use: Solid Straight Design with 1-1/2" Height

A low, straight profile keeps the geometry of your suspension tight and predictable. At 1-1/2" tall and 5-1/2" between outer bolt holes (center-on-center), it’s a compact piece that still provides the movement needed for a stable ride. The solid steel body holds up to miles of towing without bending or wearing out prematurely.

Simple Suspension Refresh: Works with Standard Shackles and Hangers

When it’s time to replace worn parts, this equalizer fits right in. Springs attach to its ends using standard shackle straps (sold separately), and it mounts from a center hanger (sold separately). Swap it in to bring back proper axle articulation, reduce bounce, and keep your trailer tracking steady and level again.

by:

Quality product, took a little longer than expected to ship, but arrived on time, no problems



by:

seem good but they were not boxed very well just thrown in a box with no padding they ended up scratching the plastic parts that were also in the box



by:

Everything is working as expected. My boat has left Atlanta and been to the Gulf of Mexico on the new equipment without problems.



by:

I have not been able to use parts as UPS lost one entire shipment, damaged another shipment and etrailer left some parts out of the replacement shipment. I want to replace all the items on my trailer together in one day.

Anyways, your company has been good about fixing the issues.

I hope UPS pays for the damage and lost shipments.



by:

The parts arrived quickly and the order was correct. This is a very good place to get parts.

by:

Really knowledgeable staff great products and quick shipping wouldn’t buy from anyone else



by:

Fit perfectly on trailer and came with bushings installed. Wasn't expecting that



by:

Original or better quality on these low profile equalizer bars. Excellent service and quick shipping. Great seller!



by:

Needed a hard to find spring equalizer, and needed it quick. Not only was it shipped promptly but the price was great. Am definitely keeping this site on my favorite list.



by:

These are a bit lighter duty looking than the bars that came off my trailer, but I was just happy to find some. The paint is pretty thin. They already have the bushings in them and fit well. They are well worth the price.



by:

It was exactly what I needed. Tried to find the equalizer every where but nothing matched. My boat trailer is a 1973 and its hard to find parts for it, but etrailer had it



by:

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.



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:)

See what our Experts say about this TruRyde Trailer Suspension Parts

  • Replacement Straight Equalizer for Existing 6-1/2 Inch Long Straight Equalizer
    To replace your existing 6-1/2 inch long straight equalizer you can use the 5-1/2 Inch Long Straight Equalizer for 1-3/4 Inch Double-Eye Springs # TREQR2 with longer shackle straps on your trailer. If you replace your 6-1/2 inch equalizer on one side, you will want to use the same set-up on the other side of the trailer as well. The # TREQR2 equalizer measures 5-1/2 inches from the center of one bolt hole to the center of the bolt hole on the other end. The equalizer is 1-1/2 inches tall...

  • How to Add Equalizer Upgrade to Older Trailer with Straight Equalizer
    The straight equalizers, like the 5-1/2" Long # TREQR2 it sounds you have, don't really have any upgrade options available as those aren't as common as the triangular versions you were talking about. In order to upgrade the suspension on your trailer you could either install a new hanger kit or you could use the outer mounting brackets for the Correct Track Trailer Alignment and Lift Kit # RR23QX to lower those by 2-1/4" so you can then use the Equa-Flex Cushioned Equalizers # LC279687....

  • Will Trailer Ride Suffer From Using Taller Equalizers
    Since the equalizer height changed by an inch, in order for your suspension to function as designed, you'll need to add 1 inch taller spring hangers to make up for the height difference. Failure to even out that height difference can result in poor ride quality, trailer sway and uneven tire wear.

  • Tandem Axle Trailer Hanger Kit that Uses Flat Center Equalizers
    Since you have a straight/flat equalizer like the part # TREQR2 you'll want to piece the parts together as we don't have a kit like the part # K71-359-00 with the style equalizer you are looking for. Which this can easily be done with just the hardware kit with the equalizer with part # LC281285.

  • Equalizer Bushing Size and Compatibility
    The only bushings we have that are 9/16" Inner Diameter, 3/4" Outer Diameter, and 1-3/4" Long are Nylon Bushings item # SP05-060. The bronze bushings from the MoRyde Suspension upgrade kit Item # MR46ZR would not fit in the TruRyde Equalizers item #TREQR2. The bushings are Outer diameter 11/16" and the Inner diameter is 9/16". The TREQR2 equalizers have a 9/16" bolt-hole diameters.

  • Do Hangers Need to be Modified or Replaced When Switching to New Equalizers on Trailer
    You shouldn't need to modify the hangers at all on your trailer when going from a straight equalizer like # TREQR2 to Y-shape units like the ones in the Triple Axle Kit # APTT5 that you were looking at. The shackle strap angle will make up for the difference between the two designs. The difference in height between the front/rear hangers and the middle hangers on your triple axle trailer is not uncommon. This is actually the more standard method than using hangers of all the same length....

  • Replacement 5-1/2 Inch Equalizers, 2-1/4 Inch Shackle Straps, and Wet Bolts for Tandem Axle Trailer
    While we don't have a kit with the parts you need that have those measurements, we can easily piece it together. You will just need the following: - Straight Equalizer for 1-3/4" Double-Eye Springs - 5-1/2" Long - 9/16" Center Hole # TREQR2 (quantity of 2) - Shackle Strap - 2-1/4" Long # TRSL225 (quantity of 8) - Wet Equalizer Bolt with Locknut and Grease Zerk for Double-Eye Springs - 3-5/16" Long # 126B2 (quantity of 14) I have added links to video reviews for you to check out as well.

  • Is There a Suspension Kit with 5-1/2" Long Straight Equalizers
    I do have an option for you though we don't really have all inclusive kits for this. The equalizer you need is the Straight Equalizer for 1-3/4" Double-Eye Springs part # TREQR2 which measures 5-1/2" long. Then for the shoulder bolts you can use the Zinc Shackle Bolt with Locknut for Double-Eye Springs part # TRFA73Z916DLNZ. I have attached our leaf spring and shackle strap selection below as well but I would need to know the length and capacity for the springs and the length for the shackles...
