What's involved with converting a 7000# trailer to something with a little more capacity. I have a 16 foot diamond deck car hauler rated at 7000#. I believe I could just swap the axles and upgrade the tires. Am I missing anything. Already has brakes.

Thanks

Often times the tires and axles are the weak link but the frame of the trailer may not be designed to hold any more than that either. I have been down this road before and you usually are time and money ahead to just sell it and buy a heavier trailer. All the conversion parts can add up fast.

5200# axles with brakes are $350 each. Springs, hangers, etc will run about $250 for the whole set. Wheels and tires maybe $180 each. I assume you want 5 including a spare. Total cost $1850. Figure in your time and you would probably be better to sell your trailer, put the $1850 you would have spent with it and buy something stouter all the way around.

I have been offered close to $2000 for my trailer, looks like take that with another $1300 or so I could have a new one. Thanks for the break down.

Make sure you find another one before you sell yours...

Hitch coupler probably needs an upgrade, too.

In August, 1990, I had that done to our 32' fifth-wheel. It was built with 3500# axles and I went to the Dexter factory in Elkhart, IN, and ordered custom built axles; 5200# axles but using the 6000# tubes (2" x 2.50"), bigger brakes, springs, shackles, nuts and bolts. But it would not be worth it for a utility trailer.

If your 7K trailer has the Mfg. ID and rating tag on it your state may not let you raise the weight limit above Mfg. specs. There is a lot more involved than swapping axles and tires for Mfgs. to get a certified rating on trailers.
Best to sell the 7K and look for a trailer with the capacity you need.

I'd be willing to say the frame wouldn't hold up, plus like George2615 wrote your state may not go along with your idea.

Totally agree. Besides, if you wanted to sell that trailer later, as a buyer, I wouldn't want to buy a trailer that someone else has converted.
