Heavy Duty U-bolt Source?

[nvrenuf]

Any suggestions for a place to get GOOD / HIGH QUALITY heavy duty u-bolts? I want 3/4" dia, 8 grade stuff (or better) bent to my specs.

I had a new "grade 8" set that I just tried to install but 2 of them stripped out. I put them on with a 1/2 ratchet (not air gun) and realized I needed to take them off to change something and the damn things were galled(?) in the nuts. These things might have been tightened to 75ftlbs.. I'm going to contact the guy I bought them from but I just don't know if I trust his source now.

5/8 and up in rod is grd8 for ubolts.

my local spring shop uses l&h rod company and thay work great.

best try the good truck/spring shops.

Wow! 3/4" is pretty thick for u-bolts on light duty trucks. I don't see how you can have any problems with that thick of bolts on our size of trucks.

I get all mine from either ITP or small hole-in-the-wall business in Salina, a town 40 miles east of me. Both have competitive prices and pretty much the same material. I use one or the other depending on if its a weekend or not.

BTW, I forgot to mention that Superlift makes good, high quality u-bolts. I know all theirs are grade 8's but they only show 1/2", 9/16" and 5/8" bolts.

you can order them from deaver spring in Santa ana california if you want something special but the super lift ones are good quality and come in most sizes.

That's exactly why I was so pissed when they stripped. I know 3/4" is big but with the 4" axle tubes "normal" size u-bolts looks kinda cheesy.

I may call Deaver and see how much they want.

I had the same problem with my 1st set of ubolts. they got a burr from the washer mashing down at the threads and it would not come off. I had to cut it and get some fresh ones. I chased the threads on the others to clean them after I pulled them off.

Sounds like a cut thread instead of a rolled thread. Even so, I would not think it would have stripped if it was actually grade 8.

stock is 9/16 rod on most. comon upgrade is 5/8 rod. fits in the plate holes and is much stronger. 3/4 is over kill to the max on a 1 ton truck. those things are on 2 ton and up.

Thank you

Thank you

No such thing as "overkill" for you, eh?

 

[nvrenuf]

Nope

I'll agree it sounds like overkill but when you actually see them installed they look perfectly natural.
