NT 5x8 trailer specs

Postby Homebrewer25 » Sat Nov 11, 2017 9:07 am

The specs on the website say the overall width of the Ironton 5x8 trailer is 76". The tires are 5.6" wide each, so it figures out to 64.8" between the tires.
Can anyone confirm that the actual width between tires on a stock NT 5x8 matches this?

How much clearance is needed between the side of the body and the tire? I'm trying to determine the maximum width that the body can be, which figures to be 64.8 - (2 x clearance).
I'm looking at making my deck exactly 5' wide (1 1/2" thick sip), then adding a 1 x 6 (3/4" x 5 1/2") skirt around it to overhang the trailer frame, locking it down. That makes it 61 1/2" wide. Then the idea is to attach the body shell thru a 1/16" diamond plate finish skirt thru the foam, the 3/4" skirt, and the trailer frame. This gives me an inside width of 61 1/2", but 65 5/8" outside width (I'm planning a foamie build with 2" foamboard).

I guess if its necessary I could eliminate the wood skirt, which reduces the body width by 1 1/2", but it still comes out to 64 1/8" width, which would only give about 3/8" clearance each side.

Does anyone see any issues with using wheel spacers to widen the track? I found some on ebay that were 1 1/4" thick, which would add 2 1/2" to the track width. These would also allow me to move up to 14" wheels/tires.

Thanks

I dont think that wide but ill measure tomortow if mo one else has weighed in. I decided to not have 1/4 ply sides over lap buy just atop frame.

Anyone with a stock NT trailer ... can you measure the distance between the tires for me?

If I recall, the hub face dimension was 70".

Subtracting half of the 5.6" tire width from each side (70" - 2.8" -2.8" ) leaves 64.4" between the tires, and 2.2" between the frame and tire.

I ended up replacing the axle with a torsion axle, so unfortunately I can't tell you for certain.

Some people have used narrower wheel spacers, but 1-1/4" wheel spacers are going to put a lot of stress on the wheel bearings and increase the forces on the axle spindle.

Thanks, Zach.

I just went to the NT site and looked at the trailer again. I had read all the questions asked (I thought) but then noticed that there were 3 more pages. One questioner asked the distance between the tire and the frame and was told it is 1.42". So on to plan B ... eliminate the 3/4" wood band around the trailer deck and attach the 2" foamboard directly to the frame side rails. But that would still require spacers, and would result in about 1/2" between the tires and the body side. This doesn't seem like it is enough.

I had planned to extend the tongue anyway, and if I have to go with a new axle, wheels, and tires then maybe I'll build the trailer from scratch. My 110v MIG welder probably doesn't have enough penetration to do a good job, so I may have to borrow a bigger welder. If I go this route then I'll probably take the opportunity to add trailer brakes. Even though I'm aiming for a sub 1000 lb TTT, it will probably be more once all the gear is added. Brakes would let me tow it behind my small car.

Sounds good Steve. For what its worth, a new axle and the tongue modification can be done without welding.

I'm not sure how TN is, but in PA the certificate of origin for the trailer makes registration 1000 times easier, which is why its popular to modify the frame rather than building from scratch. If you have some room in your budget a custom torsion axle (with brakes) may run you about $350-400 but they bolt right up and handle much better than a leaf spring axle. On my X-Cubed I went with just an idler axle, so it was a bit cheaper than one with brakes. After bolting up my new axle, I then sold the stock axle and springs for $150.
