Thanks for sharing the whole installation in this brief form. It doesn't show any of the details really clearly, but it's a good overview of the process.
Leaving the wheels and tires on, to support the axle at unloaded ride height as the suspension is replaced, is an interesting technique. It seems like they are annoyingly in the way - jack stands instead of the wheels seems like an obvious alternative, but apparently this works for them.
I find it interesting that the front brackets appear to require all new holes, instead of using the original leaf spring hanger bolt locations for at least most of the bolts. It looks like LiquidSpring uses the same brackets for all trucks, instead of designing brackets optimized to each frame design.
What are the pros and cons of Liquid Spring on a hauler bed chassis cab compared to Kelderman air ride as it relates to 1) longevity, 2) required maintenance 3) ride comfort and total cost?
We've had great success with both systems. If you would like further details to discuss what is best for you and your needs specifically please give us a call at 574-522-8422 or email at office@utilitybodywerks.com
liquid spring is an active suspension from what I can gather. I don't think anyone makes an aftermarket active air suspension as seen in luxury sedans.
I'm interested in this for my 06 ram 3500 but I'm wanting. I'm wondering if there is a variation where I can achieve a higher lift 6-8” but drop it down to a more usable hight when parked or loading. This is where this would succeed for me the most.
The International CV series (from Navistar, also sold by GM) is available from the factory with rear air suspension. It would be a lot easier to convert the air suspension to LiquidSpring (just replace shocks and air springs with LiquidSpring struts) than to convert the leaf-spring suspension; however, there would be little if any advantage to the conversion if the truck already had air suspension.
There is an air option. The only chassis we have seen them on are the 2 wheel drive units. We install both four link air suspension from Kelderman as well as the Liquid Spring suspensions.
@@MrScottrh02we have three of the 2022 international CV 4x4 chassis the the rear liquid spring systems (not installed by you). The sway is absolutely terrible, since there is not a factory rear anti-sway bar on these chassis I’m surprised one isn’t added since the factory rear leaves effectively provide that. Is there an option for rear sway bar on these chassis? The crews on all three trucks have all made their own independent comments about the handling, at this point we would all prefer to have the factory suspension even at the expense of a harsher ride provided the stability was better. It’s interesting because the Ford superduty and ram 4500-5500 platform both incorporate and retain the factory rear anti-sway bar. Any thoughts would be appreciated.
5-link structure is directed by an onboard microprocessor that simultaneously monitors speed, steering, braking, and road inputs 1000x per second using a proprietary compressible fluid as the spring mechanism to provide the optimal ride and handling characteristics at all times.
Liquids are generally relatively incompressible, compared to gases, but they do compress to some extent. This system uses a fluid, presumably silicone-based, which is more compressible than most hydraulic fluids. Since the fluid doesn't compress much (as a fraction of the uncompressed volume), the volume of fluid needs to be high, and that's why the LiquidSpring system has large fluid reservoir tanks.
The LS system uses a 6% compressible silicone fluid, and yes does it compress. Working psi is just under 3000 psi. The system also is adaptive and will change the spring rates at the rate of 40 milliseconds or 1000 times per second, each strut works independently from each other.
You can use the liquid springs filter here to look for your Year and Model liquidspring.com/support/product-literature/product-literature-details/?category=49
You're using a basic bushing style 4 link, the axle will have literally zero articulation, i noticed you guys use it on the brush trucks as well, instead of your axle being able to flex like with the use of Johnny joints or heims that you just end up twisting the frame

Glad you enjoyed it!

Can you put it on a 2024 newmar Supreme aire super c?
I emailed you guys for info on a work truck whether this liquid spring is applicable for my business, still waiting to hear back
Do they come for 18 wheeler

Hey Joshua, give Scott a call to discuss if this would work at 574-522-8422

Scott is our suspension supervisor! See his comment.

You can't put thess Liquid springs on F-450 with pick up bed, right?? Has to be the Chassis straight beams right??
Correct
The video didn’t show the installation?
Liquid doesn't compress according to the physics i was taught so how does this work?

Does this work on a single wheel F350 cab and chassis?
