There is not a bushing on the hangers used on slipper spring trailers. Smaller single axle trailers will have a bolt that runs through the hanger, while some larger and tandem axle trailers will have a welded tube that the spring sits on, but there's no need to use a bushing.

If you need to replace your hangers you can use something like the Tandem-Axle Trailer Hanger Kit for 2" Slipper Springs - 13-1/8" Long Equalizers # AP216-H238 for a tandem axle trailer or the Single-Axle Trailer Hanger Kit for 1-3/4" Slipper Springs - 1-1/2" Tall Front # APS3SE for a single axle.

The best way to choose a replacement hanger kit is by measuring the existing hangers first and matching the lengths of the current parts so that you don't change the height or suspension geometry.

As long as the weight capacity is inline with your trailer/axle rating and the measurements match your current springs, the number of leaves in a spring pack does not matter. The difference between a 3 and 4 leaf spring pack within the same weight…

Leaf springs typically have the part #stamped on the strap that holds the leafs together at one end of the shorter leafs, or it is painted on the concave side of the springs. The part number can then be used to determine the capacity of the springs.…

For a single axle trailer, you want the shackle strap to be able to move so that you have the spring deflection needed for your suspension. Angled like the photo or even almost vertical is fine you just don't want the shackle strap to bind and…

To find the load capacity for your axle you should look on the trailer VIN plate or sticker that lists the VIN number. The weight rating of the axle should be listed on that same plate or sticker. Also, the axle could have a tag or plate on it that…

Well shackle length is mainly based on the height difference between the front and rear hangers. The rear hanger normally doesn't hang as low as the front so that the shackle can offset the difference and add the ability to move. What is the…

Yes, our Dexter leaf spring part #DX74XR is the same as the part number 072-079-00. This is a 7-leaf spring for an 8,000 lb trailer axle that is 24-7/8 inches.
