4 link trade off

i have a trianglated 4 link with 25 inch lower bars and just raised the floor over the upper 4 link bars like a tunnel and still have the back seats. also u didnt mintion if its a 2 door or 4 door

4 door. I'm thinking I can put my upper bars on the outside of the frame and run my lowers inside. Got to measure tonite.

I choose a. run a forward 4-link with only like 12" long upper bars

A 12" long upper bar isn't a concern of any type. You can easily still get 10" of useable, non u-joint threatening travel. Look at the '37 Ford and the Nash on my profile. They both have upper bars shorter than 12".

Should I limit the length of the lower bar? I was going to run around 30" to make the arc large.

i hear max impregnated the virgin mary....... hey max give more info on the ackerman thread, i asked a question

I know price may become a factor but have u thought about a watts link?

Make it a 2 seater. That is what I did on my tahoe. More room for speakers and less people buggin to take a ride.

There are several different ways to address suspension that has limits to it's confines. If you do a little bit of homework on 60's GM vehicles, you will find that they have some fairly unique, but simple to mimic suspension solutions. The '60 Chevy uses a 3-link with a pannard bar, the upper bar is called a banana bar because it curves over the rearend to the tab that is mounted behind the rearend-housing. Or the '61 Cadillacs use a 3-link with an A-arm styled upper wishbone that actually uses a ball-joint that mounts behind the third-member.

When designing a system with a uncomfortably short upper bar, set up the upper bar so that it is parallel to the ground at half travel and point the lower bar up towards the front to get a fair amount of instant center and I think that you will find that you end up with more travel then expected.

As far as a watts-link... do what you want. It won't really make any difference with a long or short upper bar.

Thanks max.

I'm not to worried about how I'm going to locate it side to side yet. Plenty of room their.

I can't take the back seat out. 3 kids.
