I have a dumb question probably about suspension travel in my buggy. I am building a older sandtoys dune buggy and it has a kingpin frontend and only 7 inches between the rails where the tie rods go through. I am wondering if this is going to hinder the suspension travel if I do use a rack and longer arms and such. How much travel will I be limited to?

Well you can get a basic idea with some simple algebra.
figure out the length from inner joints to the frame rails. = x
then from the frame rails to the spindle mounts. = y
z= total movement minus some from when it turns.

((y/x)+1)7.5=z

It will give you a rough estimate as long as the neutral position of the trailing arms puts the tie rods in the middle of the frame rails. I think this works, lol.

Thanks but I haven't purchased a new beam yet and I was trying to decide between a warrior and dsrace a arm conversion if I couldn't get at least 10 inches of travel.

You could always cut out the top or bottom bar and replace it with a curved bar. Or go with a rack from a saturn or grand am that has very wide mounting points. This would allow alot more travel.

Brad,
You need to update your location so we can see where you live and what type of riding your are going to do.

If you put a Rack and Pinion, you will get some additional travel and you can also mod the frame to provide more travel.

Heres what I did on my woods buggy. Working out great so far! yes I did add more tubing before it was done

That looks awesome haven't really thought about doing it that way.

I may have used .120 wall DOM for that hoop, but its working out fine so far
