How Much To Install Airbags

2021 LC200 · December 23, 2022

Bought Rear Interruption Airbags from Australia (Airbag Human being - CR5051HP) for my 2022 LC200 purchased in the Usa.

Take ii questions:
ane) Without installing an onboard build in air compressor, what is a adept location at the rear of the vehicle for the two aggrandizement valves allowing manual inflation, i.e. using a 12v handheld air compressor? My LC200 is stock base model, so standard rear bumper etc.
2) Following the LC200 projection website by Jamie Benaud (Project 200 - Toyota LandCruiser 200 touring build) and video on the air bags installation

I am getting ready to install myself (excluding the onboard compressor and ability to command from the driver seat...). When he gets ready to lower the beam 1) he removes the rear sway bar connected to the KDSS actuator, 2 ) the shocks, 3) the diff vent hose and four) the brake line bracket. On my 2022 model, is there annihilation else i need to take care off earlier lowering the axle with the jack? I was thinking for case the headlight leveling mechanism.

Capeesh your insights. Also any pictures of your install of the two aggrandizement valves would be great.

Thanks a lot and Happy Holidays!

Subscribed, I demand to exercise this. I'll tow my boat twice a year, manual inflate will be enough good. Looks a chip more challenging than information technology was on my 80.

I've not installed air bags just I did add spacers. Information technology was non necessary to disconnect the sway bar for the drivers side but is to become the passenger side jump out. I disconnected the sway bar on the rider side because I thought it would be easier and used a bottle jack to lower and raise the bar. I don't think it actually matters which side you do.

Subscribed, I need to do this. I'll tow my boat twice a year, manual inflate volition be plenty good. Looks a fleck more challenging than it was on my eighty.

We're in the same boat...pun intended although I don't accept an 80 or a boat LOL. I'thou working on getting ready for towing, however.
I'd love to hear about a good installer in the Baltimore Maryland expanse.

Ane thing I volition do is take the lines open when not in utilise, with some filter breathers. On my eighty I figured out the air bags still had air in them to compress, even when no pressure was in them. At that place was no way I'd get full articulation unless I could permit more air out as the spring and bag compressed.

Searching this morning I found the post-obit examples of inflation valve imstalls. I showing it beside the 7 pin is not the same setup every bit my stock LC 200 (7 pivot is more nether the vehicle and at a slight angle). In whatsoever example, volition wait today a bit at the rear of the vehicle to detect a good place. I can see getting some aluminum angle material every bit a bracket to concord the valves.

Everyone who has done a nice install and is willing to share some pictures, please do!

I've been debating this. I have bags left over from my 100-series that besides fit the 200-serial.

I don't particularly accept a need for this as my rig tows great. AHC hasn't complained a bit with ride and damping on indicate. Just so the calibration has told me my rear beam is at 5000lbs when towing and then I can't help to think it may be good augmentation or backup.

Airbags are cheap and easy to install anyhow with practically no bear upon when deflated.

2021 LC200

One matter I will do is have the lines open when not in apply, with some filter breathers. On my eighty I figured out the air bags all the same had air in them to compress, even when no force per unit area was in them. There was no mode I'd get full articulation unless I could permit more air out as the spring and bag compressed.

I understand they recommend min 5psi to continue the bags and sleeves in place. I would expect articulation at 5psi and the bump stops cut off is going to be virtually the same or basically not seriously affected. Anybody with experience on an LC200, I am interested.

You can inflate the airbags easily with but a bicycle pump. No demand for ability or high tech. I mounted my valves in holes in the bumper created by removing a couple of clips. Bad idea......the valves face up down and over time salt and mud and fine sand find their manner past the seal and mess up the valve. Install them where they are protected at least a bit from road crap. The Firestone airbags I used demand a few psi all the time to go along them in place and from moving around. Since the install requires removing most of the jounce safe, I would exist non be comfortable with deflated bags. I did one side at a time and was able to get the springs out without removing the sway bar but I did open up the KDSS valves 3 turns.

Y'all can inflate the airbags easily with but a bicycle pump. No demand for power or loftier tech. I mounted my valves in holes in the bumper created by removing a couple of clips. Bad idea......the valves face up down and over fourth dimension salt and mud and fine sand detect their way past the seal and mess up the valve. Install them where they are protected at least a bit from route crap. The Firestone airbags I used demand a few psi all the time to keep them in place and from moving around. Since the install requires removing nearly of the jounce rubber, I would exist not exist comfortable with deflated bags. I did i side at a time and was able to become the springs out without removing the sway bar but I did open the KDSS valves 3 turns.

Thanks a lot for the tips. The air bags I have are Firestone with in improver numberless/sleeves to protect them. Re the droppings, I may look at some kind of plastic junction box facing rear and/or some valve covers every bit used on tires to keep them debris free. Exercise y'all mind sharing a picture of your valve install?

Not the best pictures but included considering we all love pictures. I installed Firestone airbags while keeping stock rear springs. Rear shocks are icon ii.five with remote resi. Fronts are the matching icon 2.5 coil overs without the remote resi.

It'southward been ii+ years then I don't recall exact install, however, I did utilize the OP Airbag Human video equally a reference and recollect it to be super easy install. I ran the lines to a tee and mounted the fill valve in rear bumper. I simply keep a valve stem cap on information technology to proceed dirt out. Additionally I utilise the Milwaukee m12 compact inflator when I tow to inflate and debunk. I tow a 25' airstream and quickly inflate to 25psi when towing and deflate to 5 psi when I unhitch. My cruiser pulls like a dream with this gear up. xx,000 miles with absolutely zero issues. No issues with the bags tee'd for me.

Exercise you lot heed sharing a pic of your valve install?

Mine look exactly like that of @Cruiser17 to a higher place , except I have two because I did not "T" the line. I did buy valve stalk caps with a neoprene seal inside to forestall the corrosion I mentioned earlier.

I understand they recommend min 5psi to keep the bags and sleeves in place. I would expect articulation at 5psi and the bump stops cutting off is going to be near the same or basically not seriously afflicted. Anybody with experience on an LC200, I am interested.

I guess you are right, forgot about needing pressure to go along them in identify.

I tin't help think they will limit articulation though. If you keep 5psi above atmospheric pressure level, almost 20psi absolute. Compress and so halfway, you have about 40psi absolute, about 25psi on a gauge. Cantankerous-department of near half-dozen" bore is 28 foursquare inches, 25psi X 28 = 700-lb of strength to compress the pocketbook one-half style. About 1,820-lb to compress the bag to 1/4 pinnacle. That is in improver to force required to shrink the spring.

How much spring compression until the bump-stop limits travel? If it is half the spring length from at-rest compression, possibly 700-lb won't limit it a lot. If information technology is ane/4 leap length max-travel, that would take a lot more strength to clear fully. I never really noticed a large difference in my fourscore, but my offroading in Michigan was generally construction sites with a construction trailer.

I'g also interested in hearing if anyone has checked their joint before and after installing airbags? I withal need to install them, just wondering.

Thanks for the links and pics.

I can't help think they volition limit joint though. If you keep 5psi higher up atmospheric force per unit area, about 20psi absolute. Compress and then halfway, yous have virtually 40psi absolute, about 25psi on a judge. Cross-section of about half-dozen" diameter is 28 square inches, 25psi Ten 28 = 700-lb of force to compress the bag half manner. Well-nigh 1,820-lb to compress the pocketbook to 1/4 height. That is in add-on to force required to compress the spring.

I'm also interested in hearing if anyone has checked their articulation earlier and subsequently installing airbags? I still need to install them, just wondering.

Thanks for the links and pics.

Call back now that the crash-land stops are near entirely removed which creates quite a bit of space. In add-on I empathise the traction control arrangement of the LC is so proficient that 1 wheel in the air at extreme articulation is a not result. In any example, I am installing mine to tow a travel trailer also because I prefer non to utilise a weight distributing hitch (which mechanically makes me shiver when yous consider what information technology does).

Remember now that the bump stops are almost entirely removed which creates quite a bit of space. In improver I understand the traction control system of the LC is so expert that one wheel in the air at extreme joint is a non issue. In any case, I am installing mine to tow a travel trailer as well considering I prefer not to apply a weight distributing hitch (which mechanically makes me shiver when you consider what it does).

I hold, dearest how well airbags work, even for loading the vehicle heavy. I used to load up my grown kids and all their luggage on the roof, seven of u.s. and a gold retriever, and drive four hours north. I couldn't believe how stable the 80 handled on the highway with the airbags aired up with that load.

Depending on the size of the travel trailer, particularly if it's over iv-5k lbs, I would encourage y'all to reconsider the WD hitch. If I may offer my two cents..

Air bags tin work great with heavier tongue weights, only are non a replacement for a WD hitch. They exercise completely different things. Yous tin can run safely without airbags as all they do is support the rear pause with added spring rate. But it is arguable if one can run safety without a WD hitch especially at higher loads and higher speeds, or in a dynamic situation. WD hitches restore forepart axle weight for better command and overall stability against sway, and is an important safety device particularly equally our rigs accept shorter wheelbase and relatively long rear overhangs.

Air bags can piece of work great with heavier tongue weights, just are not a replacement for a WD hitch. They practice completely different things. Yous can run safely without airbags as all they practise is back up the rear suspension with added spring charge per unit. Just it is arguable if i tin run safety without a WD hitch particularly at higher loads and higher speeds, or in a dynamic situation. WD hitches restore front axle weight for better control and overall stability against sway, and is an important safety device especially as our rigs have shorter wheelbase and relatively long rear overhangs.

Is this hitch built to transmit the forces from a weight-distribution hitch to the frame? eighty and 100 hitches didn't have a lot of structure for those kind of forces.

Cheers for pointing this out. I believe I understand what a WD hitch does and the benefit in downward force on the front end beam improving overall control. I just personally tin not become effectually the thought to transfer through some push rod system enough torque to compensate for the 500 to 800 lbs or so hitch downward force. All that force (torque) is put on the hitch and the rear chassis beam, non even because any dynamic loads equally y'all drive over bumps at speed or go through corners. Well, my program is not to use it and meet how it goes. With a heavy truck like a LC200 I expect no issue with road handling and control. In the land down under they tow with LC200's big off road capable caravans with full articulating hitches (like the Black Series HQ19 and HQ21). Obviously afterwards trying I may modify my mind and get a WD hitch.

I simply personally can not go around the idea to transfer through some push rod system enough torque to recoup for the 500 to 800 lbs or so hitch downward force. All that force (torque) is put on the hitch and the rear chassis beam, not fifty-fifty considering any dynamic loads as y'all drive over bumps at speed or go through corners. Well, my program is not to use it and run into how it goes. With a heavy truck like a LC200 I expect no issue with route treatment and control. In the state down under they tow with LC200's big off route capable caravans with full articulating hitches (similar the Black Series HQ19 and HQ21). Obviously after trying I may alter my mind and get a WD hitch.

Rather than convince you as you do seem to understand this with expert consideration... I'll add together some insight that I've learned over the years, towing at the upper end with the 200-series with an ~8,300 lb trailer. It'south wholly possible that performance is unlike at lighter weights.

- Agreed that WD forces at the hitch can be tremendous to transfer those kind of weights. Saving grace is that the structure is designed for it and the manual calls out the need to use a WD hitch with trailer weights above 5000lbs. Other variable is the amount of WD tension that is dialed in is under user control to ultimately dictate how much forcefulness is practical.
- Tweaking my WD hitch, the rig is okay with minimal tension. Information technology'southward notably better and great with appropriate tension (~fifty% FALR, front end axle load restoration). With too fiddling tension, the rig can be squirrely with passing rigs, cross winds, particularly around mountain passes, etc. Information technology becomes absolutely stable and resolute with proper setup, well into higher speeds, making towing long distances much more relaxed
- With heavier trailers, without WD, it's easy to exceed the 4300lb rear beam weight rating. Sharing that load between the axles may exist worthwhile for longevity of the axle and tires
- AUS trailer designs are different and generally use longer describe bars/tongues. This minimizes tongue weight, increases tow vehicle influence on the trailer, and increases stability.
