I've been trying to decide on aftermarket link pin beams. They will say 8" tower or 10" tower for the size of the shock stroke, but I can't find any true dimensions on how tall that really is being stock is roughly 8" above the top tube. Does anyone have these measurements? And if u put longer arms on doesn't that also change the shock stroke? I have a set of 2-1/4" longer arms and I'm trying to get as much travel as I can running torsions without cutting my Fiberglas and using a 6" wider beam.

I'm also curious about doing a long travel front linkpin. I'm going through some searches to see what come ups. Anybody have any info?

I had some guy measure his 8" tower beams, and the distance between the upper torsion tube and the center of the shock boss was 12" to about 12 1/8" if that is worth anything to you. I asked the same question because I want to fab up my own shock towers on an otherwise stock beam. Most aftermarket arms locate the shock in about the same place, so I don't think you have to worry much about changing arms. Most aftermarket arms have the mount a little closer to the link pins for better damping control. As a result, the stroke will increase a bit. Most people use the rear shocks of a Bus for the 8" towers. They are a great match for the 8" beams.

I have a set of the 10" shock tower kits which I am planning on using on a beam I am fabbing.
I measured from the top of the 2" diameter hole for the top beam tube to the center of the shock boss: 14-7/8" (Note this is angled back relative to the vertical CL's of the beam tubes).
I also measured from the top of the same tube hole to the highest point of the tower itself and got: 15-7/8"

It is hard to accurately measure how far back they are swept without getting fancy, but I am willing to give it a go if it helps. I rough measured about 4" back from the backside of the beam tubes to the shock boss hole CL.

Thanks guys, all that information helps out alot. What my plan is, is to run the tallest shock I could without cutting the front end. My baja is just shy of 16" from top tube to the bottom of the fender. So it looks like either would work, but I also herd that too much travel plays havic on the torsions.
