Frames under rear Axle......pics.....bags.....opinions?

Edited: 1/3/2006 8:28:42 AM by Chopped Mazda

Yo....Hey, ive searched around on here through the forums for some threads about frames under the rear axle. but i havet seen that many pics or examples of that setup. There has been the usuals, littleshop, the green mazda.... But im just curious to see what other people run with them. Just looking for any and all pics of the frame under the axle rear suspensions.

Also, i dont plan to run a lever styled setup....rather an bag over axle setup. How to i brace the bag bracket for what i want to do.....or how should that be built?

also, im just curious as to everyones opinion on that style setup....pros---cons. It will just be for a standard cab mini. i bassicly want it for a change to the usual backhalf. but i still want it to be driveable.



thanks

you wanna run the frame UNDER the axle... but still do a bag over axle setup?

essentially......yes. it will be alittle more put together than that but the base description of it would be that.

kinda similar to this mazda.

What i have drawn up is similar to that only by description. the frame would be narrower in width. it was going to be made from 2x3x.25, and the bag was going to sit atop the axle, and the brackets were going to come from each side of the axle (forward, and behind) in a tubular weaving fassion, for support to brace the bag. and a triangular 4-link.

Im just curious.....is that a bad design? if so, why? obviously, when i look at the one in the picture, i think the bag brackets are alittle weak and under built,(no offence to whoevers it is) but if the design was build properly, and centered atop the bag, and not pressuring the bag to twist a certain way....would it work.

thanks for your help.

2x3 1/4 wall is way too overkill, 1/8 wall will work just fine. There are a few things you need to think about though. What happens when you hit a big bump and the frame hits the axle? instead of the wheels being pushed to the gound they are gonna go airborne. Plus your wheel size pretty much determines your maximum suspension travel. I personaly don't think it's a good idea. Now if you got kinda tricky with the bag setup and did some sort of canti thing that pulled down on the axle so there is nothing above it at all, that might be cool.

That is some clean work on that frame up there. I remember seing a SICK blazer here somewhere with the frame under and it looked nice but I don't think it was a daily. I don't usually do this but I'm still going to say I don't like the idea without any good reason to think that way. Just doesn't sound safe to me. Maybe someone here can change my mind though.

2x3 1/4 wall is overkill, i know. but i have 40' of it in my garage, and dont see the need to go buy new stuff, when i can just use that. And i figured with a 20" wheel and tire combination, the overall diamiater of the wheel and tire is 28", so the distance between the top of the frame and the bottom of the axle would be 10" or so, which i figure is enough lift for me, shit i think my shocks limit me at 9" right now. I also planned on using a rubber bump stop on the frame for if it were to smack the axle at any time, but it seems to me, with the weight if i were to hit a bump, and it would have to be a pretty big one, the frame would want to travel downward more than upward...im sure it woudl have some upward swing also, but most of the pressure would force it down..?

idk.....just lookin for info....

thanks

I was actually thinking about doing this to my truck about 4yrs ago but never got a chance to mess with the idea. The first truck I saw with this kind of setup was a Fullsize. It was in the Truckin' magazine w/ only a frame and rims. It was running 22s up front and 24s in the rear I believe and was running on a Cantileve setup. If I swing by my parents I'll find out what issue it was. In my opinion its a new idea that will be used more and more but might take a few years to really get it to where people can believe that there is any kind of benefit. I have always loved the idea and if and when I do bodydrop a vehicle I will be running the same under the axle setup. If anyone knows of any pics of that Fullsize in Truckin' could you post them. Its a very well thought of design and a killer frame.

Actually, I would stick with the 1/4" wall. 1/8" wall is fine for a stock frame which is usually 4-5 inches tall, but if your going to be using 2x3 youve lost 1-2 inches in overall height so you have to make up for it in wall thickness. 1/4" is also alot heavier so your setup will ride better too.

HOLY SHIT, I'm Confused like a Virgin in the middle of a Orgy!!! lol
