Uneven movement between axles can make a trailer ride harsh and unstable. The tandem-axle hanger kit includes 7-3/4" long curved equalizers that let the axles move together smoothly so bumps and dips are absorbed evenly. This keeps your trailer tracking straight, reduces bounce, and helps the suspension move freely without binding.
Getting the correct hanger height is key to keeping the frame level and the axles aligned. This kit comes with (4) 2-1/2" tall front and rear hangers and (2) 3-1/4" tall center hangers. The taller center hanger helps balance the suspension geometry so both axles share the load evenly.
A suspension that’s too tight can’t flex the way it needs to. The included (8) 2-5/8" long shackle straps and (14) 3" long x 9/16" diameter shackle bolts with locknuts are designed for smooth movement. When installed snug—but not over-tightened—they allow the suspension to articulate freely, which prevents stress on the components and keeps travel comfortable.
Whether your trailer hauls light gear or heavy loads, this hanger kit is designed for the job. It’s made for tandem setups with 2,000-lb to 7,000-lb axles and attaches four double-eye leaf springs to the frame. The combination of durable hangers, equalizers, shackles, and hardware gives your suspension a solid connection that stays strong mile after mile.
Everything needed to hang the springs is here—front, center, and rear hangers, equalizers, shackle straps, bolts, and locknuts. Components for mounting the axle to the springs are sold separately, letting you choose the right hardware for your specific setup while keeping all the hanger parts matched and ready to go.

Today we're going to be taking a look at the tandem-axle trailer hanger kit for double-eye springs. This leaf spring mounting kit includes your equalizers, your front, center and rear hangers as well as necessary hardware for the installation. Now, components for mounting the axle to the springs are sold separately. This kit is designed for use on trailers with tandem 2,000-pound to 7,000-pound axles. This kit would be great for building a new trailer, rebuilding an old trailer, repairing or upgrading your trailer's suspension system. The hangers and the shackle straps are made from a durable steel construction. The hangers are designed to be a weld-on installation.
Located at the top of each hanger you're going to notice two holes. These are for spot welds. This kit attached four leaf springs to your trailer frame. We're just going to go over the components that are included with the kit. You're going to get four 2-1/2-inch tall hangers, two for the front and two for the rear.
Two of them act as front hangers, the other two act as rear hangers. The 2-1/2-inch tall measurement is measured from the center of the 9/16-inch diameter hole to the top of the hanger. Then you're also going to get two 3-1/4-inch tall center hangers, 3-1/4-inch measurements taken from the center of the 9/16-inch diameter hole to the top of the hanger. The kit also comes with your equalizers. These are going to be two 7-3/4-inch long curved equalizers with 9/16-inch diameter center and end holes. The 7-3/4-inch measurement comes from measuring from the center of one outer hole to the center of the other outer hole, so center-on-center 7-3/4 inches.
You're going to get your shackle straps. You're going to get eight of these and they measure 2-5/8 of an inch long. That's measured from the center of one hole to the center of the other hole. Then you're also going to get the bolts and locknuts. You're going to get fourteen 3-inch long by 9/16-inch diameter shackle bolts and fourteen 9/16-inch diameter locknuts. The center hangers are going to suspend the equalizers from the trailer frame and at each end of the equalizers connects to one end of the leaf springs with the included hardware and shackle straps.
Then the other ends of the leaf springs connect directly to the front and rear hangers with the included hardware. That's going to do it for today's look at the tandem axle trailer hanger kit for double-eye springs.

Glad we had the parts for you to get the job done Matthew! What kind of trailer did this go on?

Carries the weight well, was easy to install and keep all 4 wheels properly aligned. No unusual tire wear and the trailer travels very smoothly, even on rough road surfaces or at 85 mph.

After a year of usage the horse trailer is still doing its job - no issues with the bolts or the equalizers. Everything has held up well.
