Long Arm Question

How high of a lift would I need to use long arms for an LJ? I was thinking of going with RE 4.5 Coil Springs.

The lift height has no effect on length of control arms. You can run long arms with 2.5" springs.

Just because you have longer wheelbase in an LJ doesn't mean you can go with taller spring on stock control arms. The suspension geometry is same for both and the limits as well. This is assuming i interpreted your question correctly.

Rokmen TT, Rokmen control arms, Novak NV241 cable shifter, JKS 1.25" BL + 1" MML.

Anybody can take advice if it doesn't interfere with their plan.

Pretty sure he's asking what the minimum suspension height is for using long arms.

I thought the higher the lift it would cause my wheels to move inward. I notice that the RE 4.5 run higher than normal springs, and I noticed with the RE express 5.5 lift kit comes with long arms. I want to go a little higher because it seems what ever springs I throw into my LJ the Jeep doesn't look high enough for me.

Since someone brought up someone can have a 2.5 lift with long arms why is that? Not being sarcastic I just don't know why.

Just read this post over and over again until it makes sense. If it still doesnt, go look at your jeeps suspension then come back and read it again

I think the better question to ask is why do you think you can't? What would physically prevent you from doing it?

What are the benefits of running long arms oppose to short arms then?

That's the golden question that's going to turn this thread into a **** fest.

This is probably the most debated topic on this forum. Do some searches, you'll find your answers.

long and short is relative. its what is the best setup for your rig and what you do. from everything that i have read, I am staying with stock mounts or short arms until i can fab up some custom mid arms and all new mounts. custom mid arms with raised mount points seems to be the best option for arms, IMO
