Axle to Frame Height Difference Between Tandem Axle Hanger Kits # APT3 and # APT5

Question

Question:

We are going to build a 20foot bumper pull chassis Deck Over essentially. We are planning on doing a tandem 6K setup and was curious to see if the APT3 or the APT5 will get me the correct frame height? We were looking at 225/75 R15 Tires. Do you have any autocad drawings showing the complete assembly with springs?

We don't have CAD drawings we can give out for our hanger kits but I can help give you info to help you determine what the height of your axles relative to your trailer frame would be with each kit. With the part # APT5 it will give you approximately 4-1/2 inch to 5 inch of clearance and the part # APT3 will give you approximately 3-1/2 inch to 3-3/4 inch.

That depends on the width of the equalizer used in the suspension setup. Let's say you were using the tandem hanger kit part #APT8 though which has a 7-1/2 inch wide equalizer though. The distance between the hangers would be 28 inches using the…

Answer 6

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

Answer 8

Since both a ST145/R12 size tire, like the Kenda Karrier S-Trail #AM10130, and a 5.30-12 size tire, like the Kenda K353 #AM10068, fit a 12 inch wheel, a ST145/R12 size tire can replace a 5.30-12 size tire. Keep in mind that these tires do have…

Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same…

Answer 11

You can use leaf springs that are rated higher than the axle without any issues as long as they measure the correct measurement for your trailer. For example the 6-leaf double eye spring for 7,000 lb axles part #e64SR measures 24-7/8" eye to…

Answer 12

The two sizes you mentioned are pretty similar and fit many of the same 15 inch wheels. The 205/75-15 fits rim widths of 5 inch to 6-1/2 inch whereas the 225/75-15 fits widths that are 5 inch to 6 inch. The 205 is 27.1 inches tall and the 225 is 28.4…
