hello,
I have a 2004 rubicon with a 4 in short arm lift. My question is if i wanted to put coil spring spacers on top of my coils without doing anything else?

Stacking on 4" coils

Like Jerry mentioned, you may need a CV driveshaft to avoid having driveline vibrations.

I have an '03 TJ Rubicon, and I have been running 1" coil spacers over the rear axle (for the past 7 yrs). I had a set of 3/4" coil spacers installed in February over the front coils in order to run my 35" tires. I am still running the stock Rubicon driveshaft.

Individual results may vary :doh:

You may have driveline vibrations :facepalm:

It might be worth mentioning that I am also running a 1" body lift w/corresponding 1" MML

a BL+MML may cost more than adding spacers, but the result is very much NOT the same.

if you do some homework on how suspensions work, you'll see how your idea is bad, and why a BL+MML, with proper bumpstop extensions, is the best way to do this.

also, when going up to 35s, don't forget you'll need Vanco brakes and upgraded steering so you can drive safely on the street, regearing the axles to you can actually maintain speed on the highway, upgraded axle shafts if you wheel it, and possibly a new rear end (if you have a D35c).
