Before I get beat up on for the body mount rocker guards, they will eventually get replaced with Savvy LJ sliders. For the time being, my wife needs a step to more easily enter and exit the cabin. ;)

In your defense, I put them on there for the exact same reason with my kids. They are perfect for that.

You would have gotten away with it if you didn't mention it. Now I had to go back up and look. Lol!

I'm planning a similar brake upgrade. May I ask what pads you used on the rear? Why not BMB, price?
I already had a new set of rear Bosch BP964 QuietCast Ceramic pads. Given the bulk of the braking is handled by the front, I couldn't justify spending the extra cash. However, if I didn't have them, BMB would be on the rear.

After 2 weeks of daily driving the Jeep, I'm starting to get familiar with its mannerisms. One thing in particular is a little unsettling for me, i.e. the ride. The vehicle has what I'd describe as a "floating" ride, which is similar to cruising in a 60's era full size car. Also, when going into turns, there is considerable body roll, coupled with a sensation that the Jeep wants to shift sideways. The steering is all new and feels fine, so it's clear the suspension is the culprit.

That said, the current suspension is exactly as I bought it. New 2" springs front and rear, along with a 3/4" front spacer. Jeff told me the springs are new BDS, but I'm having a hard time validating the part numbers. When I search on the springs, Pro Comp gets identified as a partial part number match. The shocks are also new. Those are Rubicon Express, which I understand are Bilstein 5100s.

Other parts in the mix are stock control arms and rear track bar (with 100K on them), and a new JKS front track bar. I'm at a little bit of a loss on where to start here, but I only want to change one thing a time, to know what the impact is. If it helps, no substantial weight has been added, but it does have a hard top and full doors. Thoughts anyone?

My first thought when you describe the "floating ride" is shocks. But that's not how you typically hear Blilsteins described on our TJ's.

Possibly tires? Sidewall construction and/ or pressure?

Having run Bilsteins, my thoughts exactly there. I didn't check the tire pressure yet and should have thought about that one. Will validate that tomorrow. FWIW, tires are Falken Wildpeak AT3 tires 265/75R16 (C Rated).

You could try a cheap set of Monroes to see if the Bilsteins are contributing?

I already have an extra set of Black Max front shocks, so my plan, at this point, is to install those, then pull the set off the rear of my TJ and install those. That won't cost me anything but a little time and will eliminate the shocks as an issue!

If you have some other shocks you can throw on for “free” I would definitely give that a shot. Maybe pull a front control arm and see what the bushings look like? The drive side upper on the front is the one that takes a lot of wear isn’t it? Maybe check sway bar bushings as well?

Out of curiosity I just went out and bounced the rear of my TJ by hand. It took a fair amount of effort to get it to compress approximately 1/4 to 1/2". When I did the same to the LJ, it moved twice that distance with half the effort. Something is definitely not right!

Can anyone verify if these springs are BDS? I did a search and could not. What I did get was ProComp matches on 55298 and 55297.
