yeah with bags over axle you dont get much lift
hex0rz   +1y
You get as much lift as the stroke of the bag will provide when you bag it on the axle...

BTW, whatever you set your system up at with the size tire, if you go smaller or bigger it will affect how you lay out and how much lift you get.

If you get a bigger rim the tire will need to be smaller to match the overall diamter of the wheels you used to bag it with.

By going bigger in the back. You will "look" like you get more lift. But it will still be the same amount of travel provided by the bag. You may not lay out like I said if its too big a tire. Although, you are correct the notch would need to be bigger to compensate unless you match the overall diameter of the wheel you used to set the system up with.

Anyways, if I were you, depending on deep of pockets you have, I would spend alot more time studying the bag setup until you reaaaallly comprehend the whole thing. Once you do, I believe you will be able to make a better decision on what you wanna do to your existing setup.

I myself would have done it myself, lol. And I would be scrapping the rear, IF IT WERE ME. Cause I don't know what the heck that guy did, lol. But it don't look impressive.

ok.... i guess the first thing i'm going to do is figure out my pinon angle, see if its right..... also make sure my driveshaft isn't bottomed out in my tranny or almost ready to fall out, then go from there.

if the upper bag brackets are a probablem and gusseting them doesn't seem like it will work sounds like they need to be redone. if thats the case i might as well do the bag on the bar setup. think all i'll need is bars probably tabs for the bars to mount to and bag brackets? which i have no idea what that might cost...... probably like 500.00???? but it sounds easy. or if i get lucky maybe i can use the bars i already have, just relocate them.

so is the lift i'm getting way to low or is that about normal for bags over the axle? if its ok then i can set my pinon to that but until then i think i might be stuck. i believe i need to find/set my pinon angle for ride height, since not sure what my ride height is i'm stuck?

what would be a good tool to use to get the degrees of my driveshaft ect? don't know if there's a special tool that most people use.

thanks.

here i thought the front would be the hardest when i started this project.
hex0rz   +1y
I wish I had done the front first too, lol...

Go to Sears or somewhere of the likes and get an angle finder. As well, look at that link I posted up above and read the crap out of EVERY resource! Your really gonna need to study this before you jump in on this one. Well, that is if you wanna do it right!

Also, check out my project thread and read through the pages. You will see what I had to go through to learn this and you should get alot of your answers, answered.



I dunno how big the bars are that you have now, but I'm running 1" OD bars and have gussets extending the length of the bar for the links that are being used to support the bag. It all depends where you go as well in terms of prices.

Check out suicidedoors.com for parts, or contact Seth on here at Twisted Minis for some. Shoot Dev at The Bag Shack is good too. He's even got his own forum here on the board. Get ahold of him and he will hook you up.

Relocating the link bars is a good idea as well. Right now, the geometry of the bars could be totally out of whack and very undesirable for handling characteristics.

Like I said, the stroke of the bag is what determines the amount of travel. If your bag gives you 11" travel, and you get all the 11" of travel, then your fine.

Ride height is just a height you want to drive your truck at. It does'nt matter on anything except how low you wanna drive it the majority of the time. I've got mine setup at 5" off the ground. So everything on my suspension is setup for a 5" ride height, like pinion angle, 4-link, driveshaft plunge...

BTW, if you decide to put the bags on the bars, I would suggest going with square tubing for the bars, IMO. I'm sure it won't matter and some will say that round is better but, the key is how big the bars are and how thick.

Really instill this in your head that it is important to have a proper setup on a 4-link or everything will be crap and your big toy won't be very fun when your driving.

what bag gives 11" of travel?? haha, more like 7-8"

The bag might extend to 11" but its still at least 3" at compressed height, which would make it have an 8" stroke, which gives 8 inches of lift

..it was just an example.

just want to say thanks HeX0rz.... i appreciate all the help you gave me. i've been reading the links everyone has gave me and it looks like i got a lot of work ahead of me.

i think the things i'm going to focus on first are

1 get wheels/tires i'm going to use, just need to figure out a good offset to use.

2 get parts list together for bags on bar setup.

3 study the crap out of suspension geometry.

i'll keep everyone posted with my progress and questions.

thanks.

sounds like a plan
hex0rz   +1y
Actually you don't really need to get the rims and tires first. If you don't feel confident you can though.

If your rims and tires are a certain size you want and are different from the wheels you used to set up the system with you will have to redo all the stuff and whatnot. But use:


to find the OD of your wheels and set everything up with that into consideration.
