Bilstein 7100 shock travel question

So I just got my shocks for my 110 project and I am questioning if I got the wrong size.

When my truck was a 90 it had 12" travel Fox's on it and all worked perfectly.

So I just assumed I needed 12" travel for the 110 as well.

Well I seems to me on my initial gut reaction that the 12" Bilsteins are too long.

Hard to say what kind of lift I have as the rear springs came with the parts car I bought. They did have OME stickers on them so I assume they are heavy duty.

front springs are SG stage 3 off of my 90.

So I guess I would like to know what is the rule of thumb for how much shaft should be sticking out when sitting level?

The rears are not bad with about 5" or so sticking out but the fronts only have about 3" of up travel available. I know I can adjust that with bump stops but seems to me to be not enough.

Not sure if 10" travel shocks would be the way to go. Maybe only on the front perhaps?

Thanks for your help.

Shock length

2-3 inch lift should be 10 inch front with d2 towers or 12 short bodies. Other solution is go with rovertym adjustable front towers and use your 12 inch standard bodies.

Thanks Dan. I should have mentioned that I have external front shocks with custom front mounts. So shocks are not in the spring anymore.

Before it was fine with the 12 inch travel up front. Also noticed that the bodies on the 12" Fox shocks are a good inch shorter than the bodies on the new Bilstein 12" travel shocks. That could have something to do with it.

So they make short body 12" travel shocks? I think that might be the trick as I am afraid the 10" travel shocks on my setup will not be enough down travel.

Yes. Bilstein makes a 12 inch short body. Equivalent body length to standard 10 inch but with 12 inches of travel. I ran these on all four corners on my last rover. 360/80 valving on the front end.

Gotcha. That could be my solution as the rears seem pretty good with 5" of shaft showing.

So what did you run in the rear? 400/100?

Thanks for the help.

Sounds like you guys have to close to sorted but a couple of months ago I ordered Fox 2.0 Non-res for a 2" OME spring and using a D2 tower and Justin said to get the 10" travel version. I don't know what the valving is.

Haven't installed yet as I'm going to wait until I build my Toy front axle but should be a bitchin' setup when it's all done.
