I went the easy route and put Porterbuilt suspension font and back.
Would you share some information about the sway bar setup that you used in the rear.
How long are your end brackets, what bar diameter, etc.....
Supplier and part numbers would be great.
Thanks in advance for your help.

Man, you're going to test my memory.....I went out and measured the bar I have, and it's a 1.25" dia hollow bar with .25" wall, and the arms are 10" center to center in the shortest hole and 13" center to center on the longest hole (4 holes total, 1" between each), I made them adjustable so I could tune on it if need be. I'm going to start with the arms as long as possible and shorten them up until I get the truck balanced. If I remember correct, I came up with that size by using a chart that Speedway Engineering has for their sway bar torsional stiffness and I believe an 80% differential between the front and rear bar stiffness. I think I got the 80% from Rob off the Make it Handle thread....I believe the length of the bar makes a difference too on the stiffness....it's been way too long to remember for sure....

Yep....here's a link to the page with all the charts: http://www.1speedway.com/sb_rates.htm
...the length does play into it, so you have to keep that in mind. I know mine are different lengths front to rear, so I had to figure that in.

If you need anything else, let me know.
