stock height suspension refresh - 04 Unlimited

Ok - I know this is heresy - but for a variety of reasons I am going to keep my 04 Unlimited at stock height for the foreseeable future (soon to be teenage driver, short wife, don't want to lift the kayaks any higher right at the end of a long day of paddling, does what I need it to do, etc). Its on 31's that have lots of miles left so no tire size change planned for a long time.



Last time I was in for a rotate/balance, the tire guy reminded me that my stock OEM shocks were probably pretty tired after 70k miles - true. And last weekend with an oil change I noticed a little 'friendly contact' between the front drive shaft boot and the U Bracket for the front skid. Nothing serious but I could tell there was an occasional brush up from the front sitting lower than before.

So anyway I have two questions - looking for comments on my parts list below and are there any other parts I should change when I'm in there.

Front and Rear Shocks - Bilstien 4600's

Front coils - Mopar 130's
Rear coils - Mopar 106's

I'm pretty sure these are the factory coils from a 06 Rubicon Unlimited. I know they are a bit stiffer than what I have now, but I've added quite a bit of weight (rack, hard top, hitch). Someday I'd like to tow a small camp trailer and now I occasionally tow a utility trailer for dump runs, etc.

Any other soft parts I should change while I'm in there?

Appreciate any thoughts or comments.

Its tough to say how much improvement you will see from installing stock coils not knowing if your current ones are in fact worn. If I were setting up a TJ to be able to tow a trailer, I would focus on installing airbags in the rear.

Good question - how do you know if the current coils are tired?

Maybe I should just start with the new shocks and see what happens. My only real concern now is the friendly rubbing.
