Adjustable rear trailing arms how-to - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

It looked like he inserted steel into the end of the square tubing and I saw the plug welds, but the 'criss crossin' part had me confused...

Nice job... Do you have any measurements on the trailing arms, my 3/4 ton has leafs so I have no reference to build mine from also did you use 3 x 2 x ?? tube

nuke1 · 03-10-2009, 12:00 AM

Hey guys sorry for the late response. i will show some pics of what i did, these i took after the fact to show you so bear with me.

As for the angle of the arms, i traced them on white borad. i then took a cheap angle finder and made the same angle that the trailing arms were. once i found this i turned it 90 degrees and that created my angle that i had to cut out to bend my arms too. mathematics is what it is. add and subtract.

for the end piece, you are really gonna have to bear with me, i took my threaded rod and welded square stock to it in a cross fashion ( + ), then drilled coresponding holes in arms to then plug weld the stock too. this creates a stronger area than just welding it to the end.

as for the length i will find out and let you know.
If ther are any more questions just ask.

Man thats a great site. I cant build the stuff for what their selling for. Thanks!

ruffrida2005 · 08-28-2009, 03:20 PM

that's looks good.

bmfpeterson · 08-29-2009, 06:58 PM

maybe I bought the wrong steel, but I am pretty sure mine are heavier than my stock arms......def better looking and stronger (that's what I was going for)

If I remember right the angle was right around 15 degrees I'll measure mine and post what they are....

nuke1 · 08-30-2009, 01:02 PM

And here vi thought this thread was dead, hmm, good to see some ppl can use it, BMFPETERSON you will have to add some pics, i would like to see them, and to let you all know, i drove my truck finally and it handles amazing, i can crank it into a corner and she lays flat and goes, just amazing, not a truck anymore!

bmfpeterson · 10-12-2009, 02:58 PM

Here are a couple pics of what i have built..... I am waiting for a friend to machine the solid stock to slide into the arm and tap it for the hiems joint.

bmfpeterson · 02-16-2010, 01:55 PM

still waiting to get for my buddy to machine me a bung to slide in the front side...... He's been pretty busy but I got him fired up the other day and he started again hopefully next week I can have them done and ready to weld back together......

lofly'a · 02-16-2010, 08:55 PM

excellent build and write-up needs to be in HOW-TO.

Very nice! You just got rid of the articulation complaint of a 2 link.

Can someone explain what this means for those of us who dont know?

The OE truck-arms use a rubber bushing in the front. The articulation from the stock TA's comes from the I-beam style of constuction, length, & triangulated front mounting position (allowing limited twist) w/the rubber bushings. Substitute poly bushings for the rubber & you limit deflection but increase the possibility of binding.

Make a new aftermarket TA from tubular steel construction & now you've also removed the ability to flex over the length of the TA which again increases the possibility of binding.

The tubular arms offer greater strength & rigidity. Add the pivot-joint style bushing up fromt & you end up w/precise control of the arms movement w/better articulation vs. the less than stellar rubber bushing (pivot joints yeild about 33° of articulation).

You get more twist with less effort. This is great if you are building a rock crawler. It is the exact opposite of what a rear sway bar does.
