[hey you]

I have an M416 and would like to add a new axle and hubs to match my FJ40. The trailer frame width is 41” and the spring center is 39”. I am using a 10" steel wheel on the FJ40 with 3.5” backspace. I am also running 33x12.50x15 BFG MT tires.
I would also like to add electric brakes some day, does the WMS to WMS change? Will a 55” axle be the correct width for the trailer?

What axle width would you order, WMS to WMS?

Thanks!

What's the track width of your 40? Most try to match up the trailer to the tow vehicle.

If you can mock up the tires and make a measurement between them, is probably the easiest way.

Help me do the math

Thanks Guys,

I did the spring over on the trailer and it sets perfect with the cruiser. I wanted to add a custom axle and hub to match the track and the wheels on the cruiser. The track is pretty close and seems very stable if the trailer is loaded correctly. I was wondering if someone else has a simular setup that I'm seeking. The cruiser measures at about 55" WMS to WMS. I'm not comfortable with my build and thought I would ask...

Here is a shot of mine since I did the lift on the 40 I need to make a drop hitch for the trailer. Again you have a nice set up
