Features to know about

Solid Support for Heavy Loads: 5-1/4" Tall Rear Hanger Handles 3,500-lb to 9,000-lb Axles

When your trailer’s suspension starts to sag or shift, a strong mounting point keeps everything in line. This rear hanger is built 5-1/4" tall to give solid support for 2" wide slipper springs on systems rated from 3,500-lb to 9,000-lb axles. It provides the anchor point that holds the spring steady and lets the suspension move smoothly under load.

Steady Mounting You Can Count On: 5/16" Bolt Connection

A loose or undersized bolt can throw off your suspension geometry. This hanger is designed for a 5/16" diameter bolt (sold separately) that locks the slipper spring in place without extra movement. That precise fit helps the suspension track straight and keeps the ride firm and controlled.

Built for Reliable Suspension Travel: Rear Hanger Design Supports the Slipper End

Every part of the suspension has a job to do, and the rear hanger’s job is to carry the slipper end of the spring. It suspends the spring from the trailer frame and gives it a resting point for proper flex. The result is consistent travel that smooths out bumps and keeps the trailer stable mile after mile.

Versatile Use Across Trailer Builds: Works with Single, Tandem, or Triple Axle Setups

Whether you’re maintaining a workhorse or building out a custom setup, this hanger fits right in. It’s a dependable piece that works with single, tandem, and triple axle suspension systems using 2" wide slipper springs, so you can match it to your layout and keep your rig rolling straight.

Video Transcript for Detailed Breakdown of the Rear Hanger for 2" Wide Slipper Springs

Today we're going to take a look at the 5 1/4" tall rear hanger for 2" wide slipper springs. Now, this rear hanger is designed to work with trailer suspension systems that have the 2" wide slipper springs. This hanger will provide the attachment point for your lead spring. The hanger suspends the spring from the trailer frame by providing a resting place for the slipper under the spring. This hanger is designed for trailers with 3,500 up to 9,000 pound axles. Again, it's designed to fit the 2" wide slipper springs.

Does work with a 5/16 diameter bolt which we do sell separately on our website. When the give the dimension on the heighth of this, when they say 5 1/4" tall, basically that's measuring from the center of that bolt hole to the top of the hanger. If we go center to the bolt hole to the top of the hanger, that'll give you your 5 1/4" tall hanger. Now the overall dimensions I want to give you on this, we're going to measure the overall heighth from the very bottom to the very top of the hanger, that's going to be right at 6" tall. The width on it is going to be right at 2 3/4". The depth on it is going to be 3", and the inside width where the spring would go is going to be right at 2 5/16.

That should do it for the review on the 5 1/4" tall rear hanger for 2" wide slipper springs.

I just received the slipper spring hanger in the mail and it was exactly the size they said it would be. Customer service was excellent. The representative was very professional and helpful enough to get the actual slipper spring hanger I was looking to purchase and measure it to confirm it was the part I needed. Will be purchasing from etrailer again.

g with fast shipping my job was completed faster than I expected!
by:
I have purchased a number of items from etrailer.com such ans leaf springs, axle and hub assembly, and other items as well, I recently finished the trailer and it is now on a cross country trip. The trailer has just finished a 3,000 mile leg of this trip and I am told it was so smooth that it could not be felt by the towing vehicle.

Every product I have ordered from etrailer.com has been top quality and has worked extremely well. I would come back again for any of my future trailer needs.
by:
As always, etrailer came through. Exactly as ordered, fair priced and arrived sooner than estimated. Great follow-up to let me know when my package would arrive.

  • What Does Hole In Rear Hanger For 2-1/2" Wide Hanger Used For?
    The Rear Hanger for 2-1/2" Wide Slipper Springs - 6" Tall # 093026 you were looking at has a hole just to allow you to measure the height of the hanger, and the hole lines up with the bottom of the support that the hanger rests against. To measure your hanger you will need to measure from the top of the hanger to the center of the 5/16" bolt hole you mentioned to get the length. You will also need to measure the inside width of the hanger as slipper springs can be 1-3/4" - 3" wide....
