easiest way i know to tell if tubing is thick or thin wall is to look at the end crossection of it and see if its thick or thin//or measure the thickness with a micrometer

What he said.

imo thick = >.120"

The easy well to tell is looking at the corners of the tubing.

Very sharp corners will be thin wall.

Rounded corners wil be thick wall.

The tubing I used when I wrote that article was 250 thou. I used it because it was available and overkill.

I kind of agree with the guy above though, as long as it's .125 or thicker, that's pretty thick. BTW 125 tho is 1/8 of a inch.

oldblue1968chevy · 03-03-2009, 08:41 PM

hey tx firefighter, i used 2.5" thick wall tubing, got 8.5 lbs of it for 1 dollar lol

anyhow, where should i look tomroorw for someplace to get my u bolts, and will the 24" ubolt be eenough for for the added .5"

THANKS and i need help tryin to find where to get ubolts lol

He'll save some money doing it himself if he can get cheap u-bolts.

LuckyHenriksen · 03-04-2009, 01:51 AM

Ya 35 bucks is alot to spend, especially when you can usually find the tubing somewhere for cheap or free

The U-Bolts I priced were 28.00 + By the time you break a drill bit, etc. , that kit is close to the same price, I like to do this stuff, but 35.00 seems pretty cheap.

You can't use the lowering blocks in that link. Those are for leaf spring trucks. Our coil spring trucks use a much different setup.

1 dollar for the 2.5" tubing 8.5 lbs for a dollar lol

halfs the fun makin it yourself
