I’m looking for the pros and cons of the Buckstop 3 1/2” and the DBL 2 1/2” suspension kits for a CA84 F550 with 41” tires?

they are supplied by Suspension Maxx and restickered :) I custom ordered everything but the custom valved fox shocks from Suspension Maxx and went DBL over Buckstop. (YMMV) My truck is a CA60 with the Conti MPT 81 41inchers and DBL Stage 1 conversion (fox shocks)

If you want anything tolerable while unloaded you'll have to fork out for a liquid spring kit. they arent cheap but transform the nature of the dynamics of Cab and Chassis vehicles.

I spoke to Larry at liquid spring yesterday and received a similar message. The 3 1/2” lift from buckstop is bit tall. My payload is only 4,000# to 5,000# My current options is either the Suspension maxx lift kit or liquid spring setup. what do you know about liquid spring? How is the ride quality of your truck? Did you do any adjustments to the rear springs?

The stock leaf springs out back make for a lot of jounce with no camper weight on it. It shakes the cab and bounces you in the seat like a heavy duty truck should. With weight on it the jounce is noticeably better.

With the liquid spring. It's a smoother, luxury type ride. It uses a strut with compressible fluid as the damping medium with a microprocessor creating real time active suspension. . It's safer too since it adapts to road conditions and driver input. It's self leveling and height adjustable from the controls in the cab. It changes spring stiffness and damping on the fly. In all honesty, I wish it was available last year when I converted my truck. Well worth the price of admission IMHO.

The system isn't new. They've been putting it on rv's, ems rigs, and big trucks for over 10 years. The cons are the price and complexity of the install. If you price out the Pintop king system from carli with a custom Deaver pack, you are looking at the same amount of money as the liquid spring system.

thanks, I’m 100% in agreement with your conclusion.

I am over the moon happy with the Kelderman 4 link system on my Ram 5500.

Not cheap but worth every freaking cent! I have it setup for all manual operation to eliminate as many failure points as possible

Install was a bit easier and simpler than expected, took me 2 days by myself. Majority of that was getting the old stuff off

I have it setup for 2" lift in the front and stock height in the rear which ends up perfect

Calling @RAM5500 CAMPERTHING to provide his feedback on the SuspMaxx setup....

Yeahhhhh... About that...

They sent me their first kit for the 2019 Ram 4500/5500 to try out...

Long story short, i quickly yanked out the entire thing and most of its bit and spent the $ on the complete Kelderman kit.

Pros:
-It was free
-Upper adjustable control arms are hell for stout, greaseable and use nice poly bushings (still on truck)

Cons:
-Ride unchanged (its just a spacer kit)
-Front sway bar links are thinner than stock and i broke one the second time offroad
-Lower fixed control arms use low quality heims and were rusted bad within months and are not grease-able or serviceable
-No track bar bracket or adjustable track bar included

Spoke to them at length and they tried convincing me the 2019+ Rams dont need track bar adjustment for 3" of front lift.

This is most definitely incorrect as raising it 3" put the axle a full inch towards the drivers side. I measured this 6 ways to Sunday and had a few friends verify.

I was able to source a track bar relocation bracket from Buckstop and with the Kelderman setup in the front, it is now perfectly centered.

DISCLAIMER: I was given the SuspensionMaxx kit for free to review, and i already yanked it all out. From what i was told, this kit is around $2500. Which blows my mind.

So yeah... not a fan... at all

And the SuspMaxx kit is what GXV is using on their $70k "AdventureOption" package?? :ROFLMAO: :ROFLMAO: https://adventuretrucks.com/pages/adventure-truck

Camperthing ....
I have followed your build and I was suprised to see you use leveling kit spacers in the front of your truck. After seeing that and looking around I reached out to my buddy who strictly does quality custom suspension work on trucks. Him and I are big fans of Thuren and Carli. My current Ram 3500 has a mix of both and some customs parts. The truck rides and drives awesome. I recently bought a CC Ram 5500 (overland rig) for my next project. Basically we will be following the thinking of Thuren and Carli but bigger and tougher for a 5500. We have the control arms built and 3 different front coils. All the coils are 2.5 inch lift. I will start testing in the next couple of weeks on the front coils to see what ones will work best.
I will update as soon as we have some intial testing done. Also.

Thanks man!

I contacted BOTH Thuren and Carli at the beginning and both of them told me they didnt have anything whatsoever compatible with the 4500/5500s

That led me to the spacers. I used the spacers for a VERY short time and took them out and installed the Kelderman kit in the front as well.

If you come up with some 2.5" lift coils for the 5500 that ride better than stock, i will be the first in line for a set! One thing i am digging about the Kelderman though is that it moves the shock outside the spring and opens you up for a lot of different shock options.

But yeah.....

Let me know ASAP if you want/need a test dummy.
