Rough roads can make a trailer bounce and flex unevenly. The 10-1/8" long swan-shaped equalizers in this kit balance out movement between six leaf springs so each axle shares the load evenly. That means a steadier ride, less sway, and fewer jolts through the frame when the pavement gets rough.
When you’re carrying serious weight, your suspension hardware can’t be a weak link. This kit is designed for triple-axle setups rated from 3,500 lbs up to 8,000 lbs per axle, giving you solid performance for heavy-duty hauling. The parts work together to keep the suspension geometry right under load so the trailer tracks straight and stable.
Piecing together random hardware can lead to sloppy fits. This set includes everything needed to hang six leaf springs from your trailer frame—(4) 10-1/8" long equalizers, (6) 3-1/4"x5/16" spring keeper bolts, (6) 5/16" locknuts, (6) 3-1/2"x9/16" shackle bolts, (6) 9/16" locknuts, and (4) 4-1/2"x7/8" wet equalizer bolts with matching 7/8" locknuts. Each size and thread is dialed in so the fit is tight, secure, and ready to torque to spec.
Setting up suspension shouldn’t be guesswork. Pair this kit with the H302 hangers—front, center, and rear—to complete the installation. The hardware is laid out for a direct fit on triple-axle frames, keeping everything lined up for smooth motion and reliable suspension travel.
Worn or mismatched equalizers can cause binding and uneven tire wear. This kit is made for 2" wide slipper springs and uses precise 7/8" center holes and 9/16" side holes for proper alignment. With the right spacing and fit, your springs can articulate freely, giving a smoother and quieter towing experience mile after mile.

Hi, everybody. Andy here with etrailer.com. Let's take a real quick look at this triple-axle trailer equalizer kit for your 2-inch slipper springs. Now, this is designed for use on trailers with triple 3,500-pound to 8,000-pound axles. And this kit does include everything that you see here. It includes these 10-1/8-inch long equalizers and the necessary bolts for suspending your leaf springs from your trailer frame.
And you are going to use this with the H302 hangers for a complete triple-axle kit. As you can see there, that H302 kit contains the front, center, and rear hangers. So this is going to attach six leaf springs to your trailer frame. You're going to get four of these 10-1/8-inch long swan-shaped equalizers. And they come up with that measurement of 10-1/8 from the center of this hole to the end of that hanger.
So, you're going to get four of these. I do want to point out that these are a raw finish, so these will be ready to be primed and painted after you get these installed. And the center hole for mounting to the hanger is 7/8 of an inch. And the diameter of the side hole here to attach to the spring is 9/16 of an inch. And I do want to point out that this does not include the components from mounting the axle to your springs.
Well, that's going to wrap up our quick look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
