My stock Stabilizer was a pain in the ass to get off the post. I had to take the wheel off and with a large pipe and sledge beat it off. That was the hardest part. Real ball breaker ,at least for me it was

I run 7 up front and 3 in the rear. What a ride difference!! They're worth every penny.

I'm getting ready to install the in-cab controller. I crank them up to 8 or 9 in the read when towing and I'm tired of climbing under the truck every time we're headed out or returning!

I did the Cognito steering supports and Rancho stabilizer too. Tightened the steering right up (I normally run 315's)

I went with the Rancho 5000 and after 4 months they were shot on the front. Guys were saying the adjuster knobs break off of the 9K's so I didn't go with them but am thinking the next set on the front are gonna be the 9's. Or dual shocks. I'm sick of the donkey dance my truck does everytime I hit big bumps on the highway!

Yeah my stock stabilizer was welded on, used a ball joint breaker and basically demolished the oe stabilizer getting it off.

I've had the 9000xl for well over a year now. Done very well, the knobs havent seized up at all. Just changed settings at the track this past weekend.

I have been running the rancho steering stabilizer for a year now and its definetly worth it. Just installed 9000 shocks today. What setting are you guys using at the drag strip?

I know this is old, but bumping this up to share my experience. I replaced the stock shocks with the bilstein 5100's. Initial impression is a more planted feel, a little stiffer than stock. Over larger bumps and g out style bumps, the 5100's shine. Stick 10k behind the truck and they shine even brighter. The bilstein seems to fall short on small to medium chatter, which is where most of my driving is.

I switched them out for the rancho rs9000xl recently. Out of the box I grabbed the shock and I could actually compress it..... which had me a little worried. I slapped them on and the first thing I noticed was that the rear of my truck sits about 1/2" lower with the ranchos, just because the bilsteins had such a hard rebound pressure. Driving is very nice with the ranchos. All the small to medium chatter is soaked up instead of transferring straight to my spine. It does have a little more bounce on larger bumps, but not bad at all.

I prefer the rancho ride by far in comparison to the bilstein. We'll see how they hold up. I followed others advice and greased behind the adjuster knob before I put them on. Hope this helps someone on the fence.

2013 Chev 3500HD with a Fabtech 4" lift. 45,000 km. Shocks front and back and upper ball joints shot. Installed the 9000 shocks. Set them at 1... Wow. Bouncy and smooth on the blacktop. Set them at 9.... Stiff and bumpy ... Set them at 6... Still stiff and bumpy ..... Dialed them to 3... Haven't driven on them yet...but heading to work so I will see how they are on the highway and then the logging roads... I will update... But so far great shocks ... Cost $154 plus taxes each Cdn

Mine does the same thing with 9000's, stated so eloquently....:thumb:

I did fill the gaps around the adjusters with marine grease, hope it helps. The only alternative to the "donkey dance" is QA1's double adjustable in the front as suggested by othrgirl in some PM's to him...

bumping up for my 2 cents. I levelled my truck by cranking the keys and put Cognito UCA's plus a ton of everything else lol have Rancho 9000xl's all around front set to 4 and rear I can't remember right now but the truck almost rides like stock with 285/60/20's also.

Back-to-back with 5100

Just replaced Bilstein 5100 shocks (about 20-25K miles on them) with RS9000XL’s.
I never liked the 5100’s, they always struck me as way too light on rebound damping.
Initial impression on the RX9000XL (set to #6) is they are exactly what I was looking for. Not that it matters, but the 5100 looks like a shock for a 1500 and the 9000XL looks like one built for a 2500HD.
There is noticeably more control on uneven surfaces that try to shake you side-to-side and less harshness over sharp bumps. I’m convinced you need extra control for the heavier wheel/tire combos a lot of us run. I haven’t tested them on G-outs, my other pet peeve, but so far so good. Wish I would have purchased this shock to begin with.
