Central inflate/deflate.

[lsv_palana]

Hello dear friends.. very often i thinking about how to create central inflating/deflating system on our h3 like h1 have or other military cars.. in Russia we have a lot of such conversion but these cars with solid axle in front.. as for h3 rear central inflate/deflate conversion seems not hard.. but how to make it with front IFS ?
Any ideas ?

As long as the axle is central to the hub and not through a geared hub or portal type axle, you will never get CTIS to work. The airline has to be dead center of the wheel. Otherwise you have to do what concrete trucks do and run the air lines outside of the tire to the center of the hub. Either way, I'm sure its not worth the time or the money. I would invest in a good on-board air system or power tank.

You can purchase and modify them from Axletech.

** I also do not think the H3's suspension system could handle the weight of portal axles let alone the frame stress. Jeep did a demo truck called the Mighty FC and they ended up getting rid of the portal axles because the frame could not handle the stress from them even with Dana 60's as the axles. Just my 2 cents.

CTIS is nice but over-rated. It is not worth the expense of doing it.

I have contacted Axletech. They did not offer portal wheel ends for Hunmer h3...

No of course they do not offer them for the H3 for the following reasons:

1.) The H3 suspension cannot handle its own weight let alone adding 75 lbs to the ends more.

2.) You need a 7" backspacing wheel.

3.) Wrong bolt pattern


If you want to really get CTIS then go to a Dana 60 swap and do the portal ends to get functional CTIS. Other than that crazy extreme it is totally and completely not needed for the H3.
