You're rebuilding a single-axle suspension and need the hangers set at the right height. Fits 1-3/4" double-eye springs on 2,000-7,000 lb axles and includes hangers, shackles, and hardware to get everything aligned and tracking straight.
This kit is designed for 1-3/4" wide double-eye springs. The front spring eye mounts solid to the front hanger, while the rear connects through shackle straps. That setup allows the spring to lengthen slightly as it flexes, helping prevent binding and keeping the suspension moving freely.
The 3-1/4" tall front hanger raises the front spring eye compared to standard setups. This can help adjust ride height or improve clearance depending on your trailer build, while still pairing with a 1-1/4" rear hanger for proper geometry.
Hanger spacing is based on your spring length. Setting the correct distance between hangers allows the spring and shackles to move freely and helps prevent binding as the suspension cycles.

Hi, everyone. Steve here with etrailer.com. Let's take a look at our Terran Industries single-axle hangar kit for double eye springs. It's gonna feature a 3 1/4 inch tall front hangar and a rear hangar 1 1/4 inch tall. Now folks, these again are for double eye springs. You can mount 1 3/4 inch wide spring to a single-axle trailer frame.
These do support multiple weights between 2 and 7,000 pound trailer axles. And you're gonna get the full kit you see here, the six shackle bolts and nuts, the four shackle straps, the two front and rear hangers. And these are weld-on installations, so you will require welding to the frame to install these. So, if you're not sure if that's something you wanna tackle, you can use our dealer locator tab on the homepage at etrailer.com and we can help assist you finding someone local to you that can do it for you. Now, the bolts are three inch long and that's from the bottom of the head out to the tip, and the shackle strap center to center on the holes is 2 5/8 inches.
And the shackle nuts and the bolt is a 9/16 inch diameter nut. Now, we mentioned the height. You're gonna measure from the top plane here down to the center of the hole. That's that 3 1/4 inch tall and on the other hanger, from the center of the hole to the top plane, 1 1/4 quarter inch. Folks, that should do it for our quick look together.
I'm Steven. Thanks for watching.

It sounds like a frustrating install Stanislaw, but the holes are actually made that way on purpose. The bolts have splines under the head that are slightly larger than the hole, so when they’re pressed or tapped in, they bite into the hanger and keep the bolt from spinning later on. Because of that, they will feel tight and won’t slide in by hand. These bolts are meant to be installed by tapping or pressing them in with the hanger properly supported, not by pulling them through with the nut. If everything is lined up straight, they should seat with a few solid hits. Trying to draw them in with a wrench will usually just strip the threads before the splines can seat.
