Is There a Specific Hanger Recommendation for a 5,200 lbs Tandem Axle Trailer

Question

Question:

Im going to be building a deck over flat bed trailer using tandem 5200 lb axles. Ive been searching the web for hours, trying to find the measurement from axle center to bottom of the frame rail? The axle would be over slung leafs on top of the axle.

There really is no specific measurement for how tall your hangers need to be. We do offer some tandem axle suspension kits that you can choose from though.

The most popular option that we have is the Tandem-Axle Trailer Hanger Kit # APT5 which has 3-3/4" tall hangers.

I have attached a review video on the kit as well as a helpful article that demonstrates how to determine rear-to-front axle placement.

The overall spring weight rating should not be greater than the trailer's weight capacity. Although they would fit, adding springs like the 5-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 25-1/4" Long #e34SR can result in a…

While the leaf spring part #e46SR only has one pin on it that is all that's needed to secure it to either the u-bolt plate or the axle spring seat. As long as one is there that's all that's needed.

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

Thank you for providing the specs for the suspension components that you already have. Correct hanger spacing really depends on the components being used such as springs, hangers and equalizers. Most of the hanger spacing dimensions that we have are…

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…

To correctly measure a leaf spring, you'll want to jack the trailer up on jack stands so the axle is hanging freely, then measure directly across from the center of one spring eye to the other, as shown in the provided diagram. The height of the…

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…

Answer 12

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…
