Features to know about
Smoother Ride Over Rough Roads: 6-3/4" Equalizer Balances the Load
A rough road can rattle your whole setup, but this TruRyde equalizer keeps things smooth. At 6-3/4" long with 9/16" bolt holes, it connects your 1-3/4" wide double-eye springs and transfers impact evenly between the axles. That movement helps absorb bumps and distributes weight so your trailer tracks steady and your load stays level, even over uneven ground.
Reliable Motion Without Binding: Designed for Tandem and Triple Axle Suspensions
Whether you’re running a tandem or triple axle setup, this equalizer handles the job. It’s mounted from a center hanger and allows enough travel between axles to keep your suspension moving freely. When installed with properly torqued shackle bolts, it pivots smoothly without binding, maintaining consistent ride quality and suspension response mile after mile.
Built Right for a Direct Fit: Precise Hole and Height Dimensions
Getting the geometry correct matters for proper suspension action. This equalizer is built to spec with 9/16" holes at all three positions, 2-7/8" and 3-7/8" side distances from the center, and a 2" height from the shackle bolt hole to the hanger bolt hole. Those exact dimensions make it a clean fit when replacing worn or damaged parts and help keep axle alignment spot-on.
Easy Upgrade Path: Works with Standard Nylon or Never Fail Bushings
This equalizer comes set up for standard nylon bushings like #TRBU11566, but it’s also compatible with long-life options such as Never Fail bushings found in the #LC281288 upgrade kit. Swapping them in gives you a more durable, maintenance-free connection that won’t wear out, creak, or need constant replacement down the line.

The product is great. Your shipping with USPS is a poor choice. You would be far better serviced by [shipping service]. I have to often been delayed and disappointed by USPS.

The equalizers fit great, and the pin holes are the correct size to accept bronze bushings! I have found that some other places sell equalizers with oversize holes that will not hold bronze bushings. I appreciate you selling good parts that are made properly !

I've been looking for a equalizer like this for the longest time. My trailer had a stamp steel version of this with only 1 difference. The center hole is a 1in bolt and not a 9/16th. But that can be easily fixed on the trailer.

Upgraded a home built 3 axle gooseneck trailer with these to stop the center axle from wandering or becoming inverted, works great.

Although not shipped as fast as our last order, I received almost daily update on status of shipment and was advised when your supplier provided you the pivots I ordered. They arrived quickly thereafter exactly as described.

See what our Experts say about this TruRyde Trailer Suspension Parts
- Direction of Equalizer # TREQ105 When Installed on Triple Axle TrailerIn the image with the suspension setup the equalizer # TREQ105 is placed between the front and second axles. Just like you have on your trailer. The front of the equalizer connects to the spring using a shackle strap and the rear is connected directly to the spring. As shown in the other image. It's possible you have your shackle bolts too tight which can cause binding. The bolts should be torqued to yield meaning you want them tight but not so tight that the equalizers cannot move.

- Is The TruRyde Equalizer # TREQ105 Compatible With Tandem Axle Suspensions Hi Justin, Yes, the Equalizer for 1-3/4" Wide Double-Eye Springs # TREQ105 is designed for tandem and triple axle trailer suspensions.
view full answer... - Replacement Equalizers and Shackle Straps for 2007 Keystone Raptor 3712Thank you for all of that excellent information and photos! To replace the front equalizer you need the Curved Equalizer # TREQ104 and then for the rear equalizer you need the Equalizer for 1-3/4" Wide Double-Eye Springs # TREQ105. To replace your 2-3/4" long shackle straps use part # TRSL275. While you're replacing everything it would be work swapping out your bolts as well. To do this you need a 9/16" diameter bolt that's 3" long like the Redline # 126B2. If you're looking to do an...

- How Is Never Fail Hardware Kit For Triple Axle Trailer InstalledI have attached a drawing of a typical triple-axle setup you can check out. I have noted the locations you would install the # LC281288 kit shackles, bolts, sleeves, and nuts. As you can see, one of the equalizers does not use a replacement set of shackles and that is why there are 22 bolts and nuts instead of 24. This kit is designed for use on triple-axle trailers with double-eye leaf springs that have 2 EQ-105 equalizers like part # TREQ105. If you do not have a suspension setup like...

- Equalizer Recommendation for Triple Axle Trailer with Hanger Spacing of 29-1/2 inchHow long are you current equalizers? If the are 6-3/4 inch like the TREQ105 then there would be no need to move the hanger spacings. Most likely your hangers are spaced 7-3/4 inches based on the length of your springs and the current hanger spacings. You'd probably would be better off with a 7-3/4 inch equalizer like part # TREQE1 which is most likely a direct replacement.
view full answer... - Bushings Used with TruRyde Double-Eye Springs Equalizer TREQ105The Never Fail Triple Axle Suspension Upgrade Hardware Kit # LC281288 that you referenced is designed to be used with the 6-3/4" long Equalizers # TREQ105. These equalizers feature standard nylon bushings # TRBU11566, so you will definitely want to replace them with the Never Fail bushings that come included with the upgrade kit to receive full benefit. The Never Fail bushings have an extra-durable polyamide construction that simply never wears out so you don't ever have to worry about...
view full answer... - Replacement Trailer Equalizer Kit for Equalizer that Measures 7-3/4 inchesFor a cushioned set of equalizers that have 7-3/4 inches between the side holes we have the part # K71-653-00 which comes with new bolts, shackle straps, and bushings. The shackle straps of this kit are 2-1/4 inches from bolt hole center to bolt hole center. Or for a standard equalizer kit that is not cushioned we have the part # e99ZR. This also comes with bolts and shackle straps. This has 3-1/8 inches between shackle bolt hole centers.
