Raising a 2000 lb trailer axle

[Max Welton]

I have a little utility trail ... 1-ton. It's a 4'x4'x8' box with a single leaf-spring axle under it. The axle is too short and the wheels are under the box ... making the whole thing kind of high and tippy.

So I got a longer axle that will place the wheels outboard of the box and some fenders. The axle is already situated on top of the leaf spring and I want to lower the box by raising the axle. I'll make some blocks and I'll need longer u-bolts.

The biggest u-bolts I can find for a 1-3/4" axle are 4-1/4" long. Looks like I might only be able to do a one inch drop with those bolts.

If I wanted longer bolts where would I find them? No luck with my searches so far.

A local trailer supply store? Boise area has at least 12- but we're in far country.

Start with rod-stock and bend/thread your own?

See if (gulp) all-thread rod could do the trick? I have no idea what happens when it's bent..

I went to a semi repair place here in Cleveland and they bent shackles to whatever size needed.

When the axle is above the spring, those u-bolts are in tension and must hold the entire load. Making my own just doesn't sound wise.

This is pretty pricey :

But this is local :

I'll talk to the pep boys guys tomorrow.

Nearly every town has a spring shop where semi trucks go for suspension work, they can manufacture new U bolts in any size you want while you wait. My son had some made for his Toyota for ~ $10 per U last year.

Yeah, we have a TSC here but they only have standard size u-bolts. I haven't had a chance to hit pep Boyz yet..

The autozone (no pep boys in my town) carried that lowering block kit you linked to with the long u bolts at least 10 years ago since i checked. The aluminum blocks usually cracked but the bolts seemed fine.

Of course I did. They can't.

Not only that, but I was also looking for fresh tires for my John Deere 317 (1982) and they not only didn't have those, but referred me to the local Big-O to order them. Big-O was able to get the tires BTW.

The TSC in Monument CO was remarkably unhelpful for a place called Tractor Supply Company. I guess Monument isn't the same market it once was. More urban and less rural.

I put 10,000 lb axles in mine. I got the kits from a supplier in MI. I forget the place now been years.

But they have drop axles so you don't have to mount under the springs.

Those prices are too much. The U-bolts and parts were all USA made from that place. Look some shops up online. They should be all over the place.

Are you doing single or double axles? They have kits for those too. Gotta do welding though. I used a Lincoln 250 MIG to do mine.

I’ve maintained six trailers over the years with these guys
