Shock absorbers Bilstein or KONI

On the road, these Koni’s ride amazingly well. They compress and rebound faster than the stock dampers. Subjectively, this helps soak up road imperfections, but returns the tire to the road surface more quickly. This helps eliminate head toss and vibration through the chassis. Additionally, the FSD technology allows for softer compression under high frequency (large/harsh) impacts. This nets in a smooth ride over rough road conditions, but the composed and sporty handling is not compromised either. The ride feels significantly more premium.

Bilstein 5100s with proper travel (measure your old ones) then send them into Bilstein and give them your Jeep specs and what you use it for and they will tune them for you for free (you cover the shipping).

If you're just trying to level you could try a set of adjustable height Bilstein shocks. That Rancho looks like it's leaking as you've already described.

I did the Konis with the BMR SP009 springs, and while firm, the ride is comfortable and compliant.

Qmulus that is a great tip for removing that bolt. When I put my Golf R control arms and Audi solid rear bushings on our 2013 tiguan I lowered the sub frame because I was installing the dead set kit at the same time. Along with HD Bilstein shocks.

Best thing I did was put Bilstein 5100's on it in place of the Ranchos.

As was mentioned already, the Bilstein B4 is available for the front and rear of the Atlas. I have a full set of B4s on my mkV Jetta and they are fantastic. Quite firm but still comfortable. They rebound once and the party's over, unlike the Atlas which pogos down the road.

Bilstein claims around 10% stiffer dampening and rebound over OEM. I've had both B6 and B4's on my Passat, and the B4's was something I preferred more.

I put B4's on our 2008 535xi a few years ago. I first thought they were stiff but I decided the old ones were really soft. B4 was listed as the OEM equivalent.

Not apples to apples comparison but I put Bilsteins on my f150 and wish I hadn’t. They are much stiffer, great for towing but not for everything else. Would go stock if I did it again
