How does my rear shackle angle look?
« on: Mar 16, 2017, 05:09:40 PM »
I just moved my rear hangars forward about an inch because they were only angled about 5 degrees, rode like a wagon and hardly no flex. These springs have about 4 trail rides on them so far. It rides a ton better now and flexes better, but I'm thinking they may be too far forward now. They are 42-45 degrees back at rest. When the tire is fully tucked the shackles rest on the frame and act like a bump stop but the spring is almost flat at that point. What do you guys think? Should I decrease the angle some or leave it alone?

Well the angle doesn't look too bad just sitting there but I don't think they should be acting like bump stops either.  Those springs have some arch to them to get so long when they flatten out.  I would maybe swap to like 1.5" longer shackle plates and see if they don't bottom out all the way.  Then you could add some legitimate bump stops.  If you still aren't getting what you want then I would split the difference between where your front hangers were and where they are.

I am getting so I like to put multiple holes in spring hangers so I can adjust things an inch or so after it's all burned in  :).

Your pickup looks awesome by the way.  Not too huge.  1st gen is my personal favorite.

That's bad. If you hit anything hard like that you'll bend your springs. They are trying to flatten out and there is nowhere to go once the shackle hits the frame. The spring will have nowhere to go and it will buckle.

I would move the shackle hanger back like 1/2" The springs will settle as time goes. That's why common rule is to heavy tack and check angles so you don't have to grind out a whole weld. I can't tell if thats what you did. Nice rig BTW. As stated, if you can use more lift in rear try longer shackle plates.

Thanks guys for the compliments, I've worked on this truck for about 8 months now. Here is a before and after picture.  I'll try some longer shackles. I really don't want it much higher in the back. It sits pretty level right now with the front, Shackles would be worth a try, easier than cutting the hanger off. I have 5" shackles on there now, may try some 6" ones before I move the hangars. I did tack it and check it and it was a constant 35 degrees. Guess the springs just settled some.
