Same length compressed and extended. Both for front of JK.

The question is: what is different about them?

I already purchased the 1st set for my JK but I'm very curious.

 

Main difference that I see is short arm lift vs long arm lift. I would like to venture a guess why it would make a difference but I don't know so I won't.

 

Full traction suggested I get the first part number for their 3" Economy Plus lift (short arm).... even though it says for long arm. Interested in this as well.

 

Lol, good idea. My only logical guess is different valving but why would control arms dictate that?

 

I posted this same question yesterday titled shock question. I was planning on calling bilstein today at lunch but got busy and ran out of time. Keeping a eye on this thread.

 

Any expertise out there?

 

Just a little helpful thread bump.

?

 

Strictly a guess, but I would think the different length control arms would put different forces on the shock (you know, longer arm makes for a longer lever). I'm guessing different valving.

 

I see what you mean but the arms aren't really applying force. But they do allow the axle to move up more easily.

 

Oh yeah, duh! I should really get more sleep...
