Shock length for a 4" Full Traction long arm

Can someone tell me what length shocks I'll need for this suspension setup?

I'm looking into getting some Bilstein 7100s, but I don't know what length to look for.

Would a shock that's 25.8" extended and 15.8" collapsed work for either the front or the rear? It works out to roughly 10" of travel

Thanks

Really? Go measure your shock height. Add 4 inches to that. Find a shock where that number is right in the middle and you're set.

I assume that the long arm is going to have a lot more droop than the short arm is going to be able to muster. Won't that mean that I'm going to need a little more shock than just +4"?

A long arm isn't going to be much difference. Yes, it will flex better, but think about this: A 4" short arm lift will stuff the tire under the flare (with a 4" longer shock.) Will you want that long arm flexing farther than that? (Otherwise, into your fender flare.) It's gonna have about the same amount of travel because you're gonna have to bumpstop it before the tires hit the flares. The 4" of lift is what limits you, not the arm length.

So get your shock height at ride height. Find a shock where that number sits in the middle of the extended and compressed numbers and you're set. Shocks built for Jeeps should give you no problems.

Hope this helps,
-Will
