You can change out the 3500-lb axles on your enclosed trailer with higher-capacity 5200-lb axles but this will not necessarily increase the weight capacity of the trailer. The trailer manufacturer should be consulted (giving them your trailer's VIN) to allow them to determine if the other components in it, such as its frame, have the capacity to allow you to benefit from increasing the axle rating.

Also, it will likely be necessary to change your hubs to ones that are higher rated to match the new higher-rated axles.

For reference I have linked you to our main page for trailer axles where you can review the available options. You can use the filters on the page to narrow the results based on your needs.
Due to the weight of axles we can ship only Timbren systems in the 5200-lb rating, such as # ASR5200S04 with 4-inch drop spindles and brake flanges and part # ASR5200S01.

The first thing to consider is if the axle(s) are actually bent. Trailer axles have a bow in them so they are higher at the center than at the ends. When under load the axles straighten out some. That is part of how they get their capacities. If…

The hub/drum/brake assembly components are a totally different size between a 3,500 lb axle and a 5,200 lb axle. You can easily swap to the 5,200 lb axle like the part #8327816 but you will need new hub/drums like the #8-201-5UC3-EZ which has a 12…

Answer 5

Your math is correct in your trailer weight load example. If a fully-loaded tandem axle trailer weighs 4000-lbs then each of the 4 tires will bear 1/4th of that load, or 1000-lbs. In this case a tire rated for 1300-lbs would provide a good safety…

The biggest advantage and reason most people go with a larger trailer tire is the increased weight capacity that the larger tires offer. The larger diameter offers a negligible amount of better ride quality for the trailer since the larger the tire…

Answer 9

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 10

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…

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…

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…
